Sysname
GDP-alpha-D-perosamine:2-oxoglutarate aminotransferase
Reaction(IUBMB)
GDP-alpha-D-perosamine + 2-oxoglutarate = GDP-4-dehydro-alpha-D-rhamnose + L-glutamate [RN:
R10460 ]
Reaction(KEGG)
Substrate
GDP-alpha-D-perosamine [CPD:
C20638 ];
2-oxoglutarate [CPD:
C00026 ]
Product
GDP-4-dehydro-alpha-D-rhamnose [CPD:
C01222 ];
L-glutamate [CPD:

Comment
A pyridoxal 5'-phosphate enzyme. D-Perosamine is one of several dideoxy sugars found in the O-specific polysaccharide of the lipopolysaccharide component of the outer membrane of Gram-negative bacteria. The enzyme catalyses the final step in GDP-alpha-D-perosamine synthesis.
