Enzyme Information

Glucosamine-6-phosphate deaminase.
based on mapping to UniProt P0A759
Alpha-D-glucosamine 6-phosphate + H(2)O = D-fructose 6-phosphate + NH(3).
-!- 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.
