Reaction: acetyl-CoA + α-L-Rha-(1→2)-α-D-Man-(1→2)-α-D-Man-(1→3)-α-D-Gal-PP-Und = CoA + 2-O-acetyl-α-L-Rha-(1→2)-α-D-Man-(1→2)-α-D-Man-(1→3)-α-D-Gal-PP-Und
Glossary: α-L-Rha-(1→2)-α-D-Man-(1→2)-α-D-Man-(1→3)-α-D-Gal-PP-Und = α-L-rhamnopyranosyl-(1→2)-α-D-mannopyranosyl-(1→2)-α-D-mannopyranosyl-(1→3)-α-D-galactopyranosyl-diphospho-ditrans,octacis-undecaprenol
Other name(s): rfbL (gene name); wbaL (gene name)
Systematic name: acetyl-CoA:α-L-rhamnopyranosyl-(1→2)-α-D-mannopyranosyl-(1→2)-α-D-mannopyranosyl-(1→3)-α-D-galactopyranosyl-diphospho-ditrans,octacis-undecaprenol 2IV-O-acetyltransferase
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.
