SYSTEMATIC NAME
IUBMB Comments
[poly-N-acetyl-D-glucosaminyl-(1->4)-(N-acetyl-D-muramoylpentapeptide)]-diphosphoundecaprenol:[N-acetyl-D-glucosaminyl-(1->4)-N-acetyl-D-muramoylpentapeptide]-diphosphoundecaprenol disaccharidetransferase
The enzyme also works when the lysine residue is replaced by meso-2,6-diaminoheptanedioate (meso-2,6-diaminopimelate, A2pm) combined with adjacent residues through its L-centre, as it is in Gram-negative and some Gram-positive organisms. The undecaprenol involved is ditrans,octacis-undecaprenol (for definitions, click here). Involved in the synthesis of cell-wall peptidoglycan.

PBP4 is dispensable and that, as in other bacteria, its absence can be compensated for by the second class A PBP, PBP1, glycosyltransferase activity catalyzes glycan chain elongation from lipid II substrate undecaprenyl-pyrophosphoryl-N-acetylglucosamine-N-acetylmuramic acid-pentapeptide. PBP4 also catalyzes the aminolysis (D-Ala as acceptor) and hydrolysis of the thiolester donor substrate benzoyl-Gly-thioglycolate, indicating that PBP4 possesses both transpeptidase and carboxypeptidase activities

the enzyme catalyzes the assembly of lipid-transported N-acetylglucosaminyl-beta-1,4-N-acetylmuramoyl-L-Ala-gamma-D-Glu-meso-(diaminopimelic acid)-D-Ala-D-Ala units (lipid II) into linear peptidoglycan chains. These units are linked, at C1 of N-acetylmuramic acid, to a C55 undecaprenyl diphosphate. In an in vitro assay, lipid II functions both as a glycosyl donor and as a glycosyl acceptor substrate. Using substrate analogues, it is suggested that the specificity of the enzyme for the glycosyl donor substrate differs from that for the acceptor. The donor substrate requires the presence of both N-acetylglucosamine and MurNAc and a reactive group on C1 of the MurNAc and does not absolutely require the lipid chain which can be replaced by uridine. The enzyme appears to prefer an acceptor substrate containing a polyprenyl pyrophosphate on C1 of the MurNAc sugar

additional information
?
-
-
the enzyme is both an amidase and an endopeptidase. The enzyme is a lytic transglycosylase that degrades the glycan strands of the peptidoglycan into disaccharide units. The enzyme binds the cell wall, but only cleaves the glycan strands after the stem peptides have been removed. The enzyme alone is unable to cleave purified peptidoglycan but needs the presence of SpoIIP

activity of PBP1a or PBP1b can be measured in membranes by cloning the PBP into an Escherichia coli ponB::Spcr strain
-
construction of expression plasmids allowing the production of native PBP1B or PBP1B variants with an inactive transpeptidase or transglycosylase domain or both. Overproduction of the inactive PBP1B variants, but not of the active proteins, causes lysis of wild-type cells. Cells became tolerant to lysis by inactive PBP1B at a pH of 5.0
