About: Glucosaminate ammonia-lyase

An Entity of Type: enzyme, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The enzyme Glucosaminate ammonia-lyase (EC 4.3.1.9) catalyzes the chemical reaction 2-amino-2-deoxy-D-gluconate = 2-dehydro-3-deoxy-D-gluconate + NH3 (overall reaction)(1a) 2-amino-2-deoxy-Dgluconate = (2Z,4S,5R)-2-amino-4,5,6-trihydroxyhex-2-enoate + H2O(1b) (2Z,4S,5R)-2-amino-4,5,6-trihydroxyhex-2-enoate = (4S,5R)-4,5,6-trihydroxy-2-iminohexanoate (spontaneous)(1c) (4S,5R)-4,5,6-trihydroxy-2-iminohexanoate + H2O = 2-dehydro-3-deoxyD-gluconate + NH3 (spontaneous)

Property Value
dbo:abstract
  • The enzyme Glucosaminate ammonia-lyase (EC 4.3.1.9) catalyzes the chemical reaction 2-amino-2-deoxy-D-gluconate = 2-dehydro-3-deoxy-D-gluconate + NH3 (overall reaction)(1a) 2-amino-2-deoxy-Dgluconate = (2Z,4S,5R)-2-amino-4,5,6-trihydroxyhex-2-enoate + H2O(1b) (2Z,4S,5R)-2-amino-4,5,6-trihydroxyhex-2-enoate = (4S,5R)-4,5,6-trihydroxy-2-iminohexanoate (spontaneous)(1c) (4S,5R)-4,5,6-trihydroxy-2-iminohexanoate + H2O = 2-dehydro-3-deoxyD-gluconate + NH3 (spontaneous) This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is 2-amino-2-deoxy-D-gluconate 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 the pentose phosphate pathway. It employs one cofactor, pyridoxal phosphate. (en)
