Function

GTFA_AMYOR Catalyzes the attachment of 4-epi-vancosamine from a TDP donor to the beta-OH-Tyr-6 of the aglycone cosubstrate in the biosynthesis of glycopeptide antibiotic chloroeremomycin, a member of the vancomycin group of antibiotics. Strongly prefers devancoaminyl-vancomycin (DVV) as substrate rather than the heptapeptide vancomycin aglycone (AGV). Acts downstream of GtfB.[1] [2] [3]
