UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine transaminase
UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine transaminase (EC 2.6.1.92, PseC) is an enzyme with systematic name UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine:2-oxoglutarate aminotransferase.[1][2] This enzyme catalyses the following chemical reaction
- UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine + 2-oxoglutarate
UDP-2-acetamido-2,6-dideoxy-beta-L-arabino-hex-4-ulose + L-glutamate
This enzyme is a pyridoxal-phosphate protein.
