UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine transaminase EC#: 2.6.1.92; ChemWhat Code: 1378247

Product Name UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine transaminase
Example Structure Example Structure of UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine transaminase EC#: 2.6.1.92
Synonyms Cj1294, HP0366, PseC
EC Number 2.6.1.92
CAS Registry Number
Comments A pyridoxal 5′-phosphate protein. The enzyme transfers the primary amino group of?L-glutamate to C-4” of UDP-4-dehydro sugars, forming a C-N bond in a stereo configuration opposite to that of UDP. The enzyme from the bacterium?Bacillus cereus?has been shown to act on UDP-2-acetamido-2,6-dideoxy-¦Â-L-arabino-hex-4-ulose, UDP-¦Â-L-threo-pentapyranos-4-ulose, UDP-4-dehydro-6-deoxy-D-glucose, and UDP-2-acetamido-2,6-dideoxy-¦Á-D-xylo-hex-4-ulose.?cf. EC?2.6.1.34, UDP-N-acetylbacillosamine transaminase, which catalyses a similar reaction, but forms the C-N bond in the same stereo configuration as that of UDP.
Cofactor pyridoxal 5′-phosphate
History
Reactions 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.
