ENZYME entry: EC 2.6.1.92
Accepted Name |
UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine transaminase.
|
Alternative Name(s) |
UDP-4-dehydro-6-deoxy-D-glucose transaminase. |
UDP-beta-L-threo-pentapyranos-4-ulose transaminase. |
Reaction catalysed |
2-oxoglutarate + UDP-4-amino-4,6-dideoxy-N-acetyl-beta-L-altrosamine <=> L-glutamate + UDP-2-acetamido-2,6-dideoxy-beta-L-arabino-hex-4-ulose |
Comment(s) |
- 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-beta-L-arabino-hex-4-ulose, UDP-beta-
L-threo-pentapyranos-4-ulose, UDP-4-dehydro-6-deoxy-D-glucose,
and UDP-2-acetamido-2,6-dideoxy-alpha-D-xylo-hex-4-ulose. cf.
EC 2.6.1.34, which catalyzes a similar reaction, but forms the C-N
bond in the same stereo configuration as that of UDP.
