ID 2.3.1.303 DE alpha-L-Rha-(1->2)-alpha-D-Man-(1->2)-alpha-D-Man-(1->3)-alpha-D-Gal- DE PP-Und 2(IV)-O-acetyltransferase. CA acetyl-CoA + alpha-L-Rha-(1->2)-alpha-D-Man-(1->2)-alpha-D-Man-(1->3)- CA alpha-D-Gal-di-trans,octa-cis-undecaprenyl diphosphate = alpha-L-2OAcRha- CA (1->2)-alpha-D-Man-(1->2)-alpha-D-Man-(1->3)-alpha-D-Gal-di-trans,octa- CA cis-undecaprenyl diphosphate + CoA. CC -!- The enzyme, present in Salmonella strains that belong to group C2, CC participates in the biosynthesis of the repeat unit of O antigens CC produced by these strains. //
