Glucosamine-6-phosphate deaminase

In enzymology, a glucosamine-6-phosphate deaminase (EC number|3.5.99.6) is an enzyme that catalyzes the chemical reaction

:D-glucosamine 6-phosphate + H₂O $ightleftharpoons$ D-fructose 6-phosphate + NH₃

Thus, the two substrates of this enzyme are D-glucosamine 6-phosphate and H₂O, whereas its two products are D-fructose 6-phosphate and NH₃.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in compounds that have not been otherwise categorized within EC number 3.5. The systematic name of this enzyme class is 2-amino-2-deoxy-D-glucose-6-phosphate aminohydrolase (ketol isomerizing). Other names in common use include glucosaminephosphate isomerase, glucosamine-6-phosphate isomerase, phosphoglucosaminisomerase, glucosamine phosphate deaminase, aminodeoxyglucosephosphate isomerase, and phosphoglucosamine isomerase. This enzyme participates in aminosugars metabolism. This enzyme has at least one effector, N-Acetyl-D-glucosamine 6-phosphate.
