l136

Description

UDP-4-dehydro-6-deoxy-D-glucose aminotransferase (2.6.1.-)

Alternative names

UDP-4-keto-6-deoxy-D-glucose-oxoglutarate aminotransferase;
UDP-viosamine--glutamate aminotransferase;
L136

Catalyzed reaction

UDP-4-dehydro-6-deoxy-D-glucose + L-glutamate = UDP-4-amino-4,6-dideoxy-D-glucose + 2-oxoglutarate.

Cofactor

Pyridoxal phosphate.

Comments

The only functionally validated enzyme enzyme is from the giant Mimivirus, which infects several Acanthamoeba species.
Apparently viosamine, the final product of the pathway involving L136, is used by this virus to form glycosylated fibers - resembling polysaccharides from bacterial cell walls - that cover the virion and promote phagocytosis by the host cells.
