ENZYME entry: EC 3.5.99.6

Accepted Name
Glucosamine-6-phosphate deaminase.
Alternative Name(s)
GlcN6P deaminase.
Glucosamine phosphate deaminase.
Glucosamine-6-phosphate isomerase.
Phosphoglucosamine isomerase.
Phosphoglucosaminisomerase.
Reaction catalysed
Alpha-D-glucosamine 6-phosphate + H(2)O <=> D-fructose 6-phosphate + NH(3)
Comment(s)
  • Isomerization of the aldose-ketose type converts the -CH(-NH(2))-CH=O group of glucosamine 6-phosphate into -C(=NH)-CH(2)-OH, forming 2-deoxy-2-imino-D-arabino-hexitol which then hydrolyzes to yield fructose 6-phosphate and ammonia.
  • N-acetyl-D-glucosamine 6-phosphate, which is not broken down, activates the enzyme.
  • Formerly EC 5.3.1.10.
