EC	2.4.1.311
Accepted name:	chloroorienticin B synthase
Reaction:	dTDP-β-L-4-epi-vancosamine + desvancosaminyl-vancomycin = dTDP + chloroorienticin B
Glossary:	dTDP-β-L-4-epi-vancosamine = dTDP-3-amino-2,3,6-trideoxy-3-methyl-β-L-arabino-hexopyranose desvancosaminyl-vancomycin = vanomycin pseudoaglycone
Other name(s):	GtfA
Systematic name:	dTDP-L-4-epi-vancosamine:desvancosaminyl-vancomycin vancosaminyltransferase
Comments:	The enzyme from the bacterium Amycolatopsis orientalis is involved in the biosynthesis of the glycopeptide antibiotic chloroeremomycin.
