2.4.1.380

Accepted name:

GDP-Man:α-D-Man-(1→3)-α-D-Gal diphosphoundecaprenol α-1,2-mannosyltransferase

Reaction:

GDP-α-D-mannose + α-D-Man-(1→3)-α-D-Gal-PP-Und = GDP + α-D-Man-(1→2)-α-D-Man-(1→3)-α-D-Gal-PP-Und

Glossary:

α-D-Man-(1→3)-α-D-Gal-PP-Und = α-D-mannopyranosyl-(1→3)-α-D-galactopyranosyl-diphospho-ditrans,octacis-undecaprenol
α-D-Man-(1→2)-α-D-Man-(1→3)-α-D-Gal-PP-Und = α-D-mannopyranosyl-(1→2)-α-D-mannopyranosyl-(1→3)-α-D-galactopyranosyl-diphospho-ditrans,octacis-undecaprenol

Other name(s):

wbaW (gene name); rfbW (gene name)

Systematic name:

GDP-α-D-mannose:α-D-mannopyranosyl-(1→3)-α-D-galactopyranosyl-diphospho-ditrans,octacis-undecaprenol 2^II-α-mannosyltransferase (configuration-retaining)

Comments:

The enzyme, present in Salmonella strains that belong to group C2, participates in the biosynthesis of the repeat unit of O antigens produced by these strains.
