Glucosaminate ammonia-lyase

In enzymology, a glucosaminate ammonia-lyase is an enzyme that catalyzes the chemical reaction


 * D-glucosaminate $$\rightleftharpoons$$ 2-dehydro-3-deoxy-D-gluconate + NH3

Hence, this enzyme has one substrate, D-glucosaminate, and two products, 2-dehydro-3-deoxy-D-gluconate and NH3.

This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is D-glucosaminate ammonia-lyase (isomerizing 2-dehydro-3-deoxy-D-gluconate-forming). Other names in common use include glucosaminic dehydrase, D-glucosaminate dehydratase, D-glucosaminic acid dehydrase, aminodeoxygluconate dehydratase, 2-amino-2-deoxy-D-gluconate hydro-lyase (deaminating), aminodeoxygluconate ammonia-lyase, 2-amino-2-deoxy-D-gluconate ammonia-lyase, and D-glucosaminate ammonia-lyase. This enzyme participates in pentose phosphate pathway. It employs one cofactor, pyridoxal phosphate.
