2.4.1.143 alpha-1,6-mannosyl-glycoprotein 2-beta-N-acetylglucosaminyltransferase
IUBMB Comments
The enzyme, found in plants and animals, participates in the processing of N-glycans in the Golgi apparatus. Its activity initiates the synthesis of the second antenna of di-antennary complex N-glycans. While the natural substrate (produced by EC 3.2.1.114, mannosyl-oligosaccharide 1,3-1,6-α-mannosidase) is described here, the minimal substrate recognized by the enzyme is α-D-Man-(1→6)-[β-D-GlcNAc-(1→2)-α-D-Man-(1→3)]-β-D-Man-R.
The enzyme appears in viruses and cellular organisms

additional information
evolution
enzyme TbGT15 belongs to the trypanosome beta3-glycosyltransferase superfamily
evolution
compared with the structure of human GnTII, the amino acid residues involved in catalytic activity and substrate recognition are almost fully conserved in Bombyx mori GnTII, which is consistent with its enzymatic properties
evolution
MGAT2 has been characterized from mammalian, plant, and insect sources, enzyme structure comparisons, overview
evolution
-
enzyme TbGT15 belongs to the trypanosome beta3-glycosyltransferase superfamily
-
malfunction
deletion of TbGT15 is accompanied by the absence of complex N-glycans, as well as alterations in the biosynthesis of the giant poly-Lac-dently from prior TbGnTI action, which is in contrast to canonical GnTIIs that only use substrates after modification by GnTI, i.e. Manalpha1-6(GlcNAcbeta1-2Manalpha1-3)Manbeta1-4GlcNAcbeta1-4GlcNAc
malfunction
human deficiency in MGAT2 leads to carbohydrate-deficient glycoprotein syndrome type IIa (CDG IIa) characterized by facial dysmorphy, ventricular septal defects, and severely retarded psychomotor development. To date, five MGAT2 mutations have been identified in CDG IIa patients, all residing within the catalytic domain (H262R, S290F, N318D, C339ter, and K237N). Four of the mutations (H262R, S290F, N318D, C339ter) exhibit significantly reduced (compound heterozygote N318D:C339ter) or a complete absence of enzyme activity (H262R, S290F). Three of the residues are nonconserved (H262, N318, and K237), and N318 and K237 H-bond directly or indirectly with the UDP-GlcNAc donor. The S290 is a conserved residue that stabilizes the core of the GT-A fold through H-bonds to peptide bond backbone residues. The H262R, S290F, and K237N mutations break these critical hydrogen bonds and introduce steric clashes to destabilize the protein. The isosteric N318D mutation results in reduced activity similar to the 30 to 37fold reduction in kcat/Km for the N318A
malfunction
prolonged stress induced by tunicamycin or sodium chloride treatment increased causes severe developmental damage in GnTII loss-of-function mutants (gnt2-1 and gnt2-2). The absence of the 6-arm GlcNAc residue in the N-glycans in gnt2-1 facilitates the TM-induced unfolded protein response, accelerates dark-induced leaf senescence, and reduces cytokinin signaling, as well as susceptibility to cytokinin-induced root growth inhibition. gnt2-1 and gnt2-2 seedlings exhibit enhanced N-1-naphthylphthalamic acid-induced inhibition of tropic growth and development

metabolism
N-acetylglucosaminyltransferase I or II initiate the elaboration of the Manalpha1-3 and Manalpha1-6 arms, respectively, of the conserved trimannosyl-N-acetylchitobiosyl core of N-linked glycans. Proposed scheme for poly-LacNAc-containing N-glycans of bloodstream form trypanosomes, overview
metabolism
beta-1,2-N-acetylglucosaminyltransferase II is a key enzyme for complex-type N-glycan biosynthesis. Both insect and mammalian cells produce Man(alpha1->6)[GlcNAc(beta1->2)Man(alpha1->3)]Man(beta1->4)GlcNAc(beta1->4)GlcNAc (MGn) glycan as an intermediate during N-glycan processing. In insect cells, beta-N-acetylglucosaminidase (fused lobes, FDL) removes a GlcNAc residue of the alpha1-3 arm of MGn glycan to produce Man(alpha1->6)[Man(alpha1->3)]ManGlcNAc2 (MM), a core structure from paucimannose-type N-glycans
metabolism
Asn-linked oligosaccharides are extensively modified during transit through the secretory pathway, first by trimming of the nascent glycan chains and subsequently by initiating and extending multiple oligosaccharide branches from the trimannosyl glycan core. Trimming and branching pathway steps are highly ordered and hierarchal based on the precise substrate specificities of the individual biosynthetic enzymes. A key committed step in the synthesis of complex-type glycans is catalyzed by N-acetylglucosaminyltransferase II (MGAT2), an enzyme that generates the second GlcNAcbeta1,2- branch from the trimannosyl glycan core using UDPGlcNAc as the sugar donor. Enzymatic steps required for the synthesis of the complex-type structures, processing of N-glycans from Man9GlcNAc2 to complex-type structures includes GlcNAc addition by MGAT1, Man trimming by MAN2A1, and GlcNAc addition by MGAT2, pathway overview

physiological function
TbGT15 is the glycosyltransferase responsible for the transfer of beta1-2-linked GlcNAc to the alpha1-6-linked alpha-D-mannopyranosyl residue of Manalpha1-6(Manalpha1-3)Manbeta1-4GlcNAcbeta1-4GlcNAc. The enzyme initiates the elaboration of the Manalpha1-6 arms of the conserved trimannosyl-N-acetylchitobiosyl core of N-linked glycans, structure and biosynthesis of complex N-glycans in the human pathogen are analyzed, and the adaptation by trypanosomes of beta3-glycosyltransferase family members to catalyze beta-1-2 glycosidic linkages is demonstrated. TbGT15 is a non-essential gene in Trypanosoma brucei bloodstream form cells
physiological function
beta-1,2-N-acetylglucosaminyltransferase II (GnTII) is a Golgi-localized type II transmembrane enzyme that catalyzes the transfer of N-acetylglucosamine to the 6-arm of the trimanosyl core of N-glycans, an essential step in the conversion of oligomannose-type to complex-type N-glycans
physiological function
beta-1,2-N-acetylglucosaminyltransferase II (GnTII) catalyzes the transfer of GlcNAc from a UDP-GlcNAc donor to the alpha1-6 arm of MGn glycan to produce biantennary complex-type glycans in mammalian cells
physiological function
promotion of the 6-arm GlcNAc addition to N-glycans by the activity of N-acetylglucosaminyltransferase II is important for plant growth and development under stress conditions, possibly via affecting glycoprotein folding and/or distribution

additional information
Rossmann-like fold that employs conserved divalent cation-dependent substrate interactions with the UDP-GlcNAc donor. MGAT2 interactions with the extended glycan acceptor are distinct from other related glycosyltransferases. These interactions are composed of a catalytic subsite that binds the Man-(alpha1,6)- monosaccharide acceptor and a distal exosite pocket that binds the GlcNAc-beta1,2Man-alpha1,3Manbeta- substrate recognition arm. Substrate binding by MGAT2 employs both conserved and convergent catalytic subsite modules to provide substrate selectivity and catalysis. More broadly, the MGAT2 active-site architecture demonstrates how glycosyltransferases create complementary modular templates for regiospecific extension of glycan structures in mammalian cells. The enzyme MGAT2 employs a UDP-GlcNAc donor in a Mn2+-dependent inverting catalytic mechanism. structural basis for substrate recognition by MGAT2, structure-function analysis, structure comparisons, catalytic mechanism, detailed overview

gene replacement strategy is used to create TbGT15 null mutant cells and subsequent insertion of tetracycline-inducible ectopic copy. Constructs for gene replacement and ectopic expression are stably transformed into Trypanosoma brucei bloodstream form cells (strain 427, variant 221). Mouse infectivity studies with wild-type and TbGT15 null mutant bloodstream form trypanosomes. No morphological differences between the wild-type and TbGT15 null mutant parasites are ascertained by light microscopy or by scanning electron microscopy. Compared with wild-type cells, the TbGT15 null mutant parasites exhibit slightly slower growth kinetics in vitro, and this mild growth phenotype is partially reversed in TbGT15 conditional null cells grown under permissive conditions. In addition, no difference in its ability to infect mice can be detected for the TbGT15 null mutant. Mutant phenotype, overview

construction of a Gnt II-expressing alg3 mutant strain of Pichia pastoris. Engineering of an artificial glycosylation pathway in Pichia pastoris blocked in dolichol oligosaccharide assembly
construction of a silkworm-based Bombyx mori nucleopolyhedrovirus bacmid expression system, and functional expression of His-FLAG-tagged human GnTII (hGnTII) lacking the N-terminal cytosolic tail and transmembrane region. The enzyme is secreted. The enzyme expressed in silkworm is glycosylated, the structure of N-glycans in the recombinant hGnTII is suggested to be of the complex type, pauci-mannosidic-type glycans, and the removal of the glycans does not affect the enzymatic activity

The recombinant enzyme exhibits similar pH and temperature dependency and the same substrate specificity as human GnTII expressed by the same system, but deglycosylation with peptide:N-glycanase F does not affect its enzymatic activity. Construction of a vector including the N-terminally FLAG (DYKDDDDK)-tagged lumenal region (Leu27eAla498) including the stem domain and the catalytic domain of BmGnTII together with a signal peptide sequence from bombyxin and transformed into Escherichia coli BmDH10Bac-CP-/Chi- competent cells, which contain the cysteine protease- and chitinase-deficient BmNPV bacmid. RT-PCR expression analysis. The cDNA templates are synthesized from total RNAs extracted from whole bodies of first to fifth-instar larvae and pupa and tissues of fifth-instar larvae. Tissues used are as follows: fat body, midgut, silk gland, epidermis, and Malpighian tubule. To produce the soluble form of BmGnTII n hemolymph, chitosan/BmNPV bacmid nanocomplexes are prepared and then injected into fifth-instar silkworm larvae. The bacmid-injected larvae are reared on an artificial diet
