ENZYME entry: EC 4.3.1.9

Accepted Name
glucosaminate ammonia-lyase
Alternative Name(s)
2-amino-2-deoxy-D-gluconate ammonia-lyase
2-amino-2-deoxy-D-gluconate hydro-lyase (deaminating)
acetylenemonocarboxylic acid hydrase
aminodeoxygluconate ammonia-lyase
aminodeoxygluconate dehydratase
D-glucosaminate dehydratase
D-glucosaminic acid dehydrase
glucosaminic dehydrase
Reaction catalysed
2-amino-2-deoxy-D-gluconate <=> 2-dehydro-3-deoxy-D-gluconate + NH4(+)
Comment(s)
  • The enzyme releases an unstable enamine product that tautomerizes to an imine form, which undergoes spontaneous hydrolytic deamination to form the final product.
  • Formerly EC 4.2.1.26 and EC 4.3.1.21.
