the chain length of bacterial lipopolysaccharide O antigens is determined in the ATP-binding cassette (ABC) transporter-dependent pathway. Escherichia coli O8 polymannan is synthesized in the cytoplasm, and an ABC transporter exports the nascent polymer across the inner membrane prior to completion of the lipopolysaccharide molecule. The polymannan O antigens has nonreducing terminal methyl groups. The 3-O-methyl group in serotype O8 is transferred from S-adenosylmethionine by the WbdDO8 enzyme, and this modification terminates polymerization. Methyl groups are added to the O9a polymannan in a reaction dependent on preceding phosphorylation. The bifunctional WbdDO9a catalyzes both reactions

Model for export of lipopolysaccharide (LPS) O-antigen polysaccharide (O-PS) via ABC transporters. In O9a biosynthesis, the chain-terminator enzyme WbdD caps the nonreducing end of the glycan with a methylphosphate moiety and thereby establishes chain-length distribution. A carbohydrate-binding module (CBM) in the ABC transporter recognizes terminated glycans, ensuring that only mature O-PS is exported and incorporated into LPS. Each CBM can bind the O-PS only with the native repeat unit, revealing that methylphosphate is essential but not sufficient for substrate recognition and export

physiological function
-
the glycan of the polymannose O-polysaccharide of Escherichia coli O9a is assembled on a 55-carbon lipid acceptor (undecaprenyl phosphate) in the inner (cytoplasmic) membrane. Chain extension is mediated by three mannosyltransferases, designated WbdCBA, and occurs by the addition of mannose residues to the non-reducing terminus of the glycan. The chain length of the O9a O-polysaccharide is controlled by the activity of the WbdD protein by addition of methylphosphate to the non-reducing terminus
physiological function
-
the WbdD proteins control the chain length of the Escherichia coli O9a polymannan by modifying the nonreducing end of nascent undecaprenol diphosphate-linked polymer. Overexpression of WbdD decreases O-polysaccharide chain length. WbdD activity coordinates polymannan chain termination with export across the inner membrane
physiological function
-
WbdD controls polymerization reaction in biosynthesis of the O-polysaccharide by coordinating the correct membrane association required for activity of one of the critical mannosyltransferases, WbdA. Identification of regions in the C terminus of WbdD that contribute to the interaction
physiological function
-
In Escherichia coli O9a, the peripheral membrane protein WbdD terminates polymerization by adding a methyl phosphate to the non-reducing end of the nascent O9a polymer. The O9a system is a representative of the widespread ATP-binding cassette transporter-dependent assembly pathway. This terminal modification is required for recognition and export of the completed O-PS across the cytoplasmic membrane by its cognate ATP-binding cassette transporter. The recognition event is mediated by the nucleotide-binding domain polypeptide of the transporter, which possesses a serotype-specific carbohydrate-binding module that only binds terminated O-PS chains. The WbdD terminator plays an additional pivotal structural role in recruiting WbdA to the membrane. The stoichiometry of WbdA:WbdD in active complexes is a critical factor in establishing the chain length distribution of the resulting glycans. The size of the O9a polysaccharide is determined by the chain-terminating dual kinase/methyltransferase (WbdD) that is tethered to the membrane and recruits polymerase/glycosyltransferase WbdA into an active enzyme complex by protein-protein interactions. Identification via bacterial two-hybrid analysis of a surface-exposed alpha-helix in the C-terminal mannosyltransferase domain of WbdA as the site of interaction with WbdD, the C-terminal domain was unable to interact with WbdD in the absence of its N-terminal partner. The WbdD protein orchestrates critical localization and coordination of activities involved in chain extension and termination. Complex domain interactions are needed to position the polymerase components appropriately for assembly into a functional complex located at the cytoplasmic membrane. WbdD is therefore a central player in a sophisticated quality control system that dictates the distribution of chain lengths and marks those chains with a terminal export tag
physiological function

the enzyme WbdD takes part in the biosynthesis of lipopolysaccharide O-antigen in Klebsiella pneumoniae strain O7, pathway overview. In the simpler process exhibited by Klebsiella pneumoniae serotype O2a, the O-PS is polymerized to completion within the cytosol by a biosynthetic enzyme complex. The chain-length distribution is controlled by the relative activities of a complex of glycosyltransferase (GT) enzymes and the ABC transporter. The O2a ABC transporter does not possess strict O-PS specificity, and it can export polymers with diverse repeat-unit structures, but polymerization and export are obligatorily coupled
physiological function
the more intricate Escherichia coli serotype O9a O-antigen polysaccharide (O-PS) assembly system incorporates an additional mechanism that imposes a stricter level of control over chain length. This requires the installation of a chain-terminating residue that creates an export signal recognized by a carbohydrate-binding module (CBM) attached to the ABC transporter. In this system, polymerization and export can be temporally uncoupled in vitro. In O9a biosynthesis, a chain-terminator enzyme, WbdD, caps the nonreducing end of the glycan with a methylphosphate moiety and thereby establishes chain-length distribution. A carbohydrate-binding module (CBM) in the ABC transporter recognizes terminated glycans, ensuring that only mature O-PS is exported and incorporated into LPS. Enzyme WbdD has both kinase and methyltransferase activities. Although the kinase activity is solely responsible for chain-length regulation, both activities are essential for CBM recognition and export. Each CBM can bind the O-PS only with the native repeat unit, revealing that methylphosphate is essential but not sufficient for substrate recognition and export
