Crystal Structure of TDP-epi-Vancosaminyltransferase GtfA in complexes with TDP and the acceptor substrate DVV.Crystal Structure of TDP-epi-Vancosaminyltransferase GtfA in complexes with TDP and the acceptor substrate DVV.

Structural highlights

1pn3 is a 4 chain structure with sequence from Amycolatopsis orientalis. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.8Å
Ligands:, , , , , ,
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

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]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
