CA   alpha-D-galactosyl-di-trans,octa-cis-undecaprenyl diphosphate + GDP-
CA   alpha-D-mannose = alpha-D-mannosyl-(1->3)-alpha-D-galactosyl-diphospho-
CA   di-trans,octa-cis-undecaprenol + GDP + H(+).
CC   -!- The enzyme, present in Salmonella strains that belong to group C2,
CC       participates in the biosynthesis of the repeat unit of O antigens
