Identification
Name:2-keto-3-deoxy-L-rhamnonate aldolase
Synonyms:
  • KDR aldolase
  • 2-dehydro-3-deoxyrhamnonate aldolase
  • 2-keto-3-deoxy acid sugar aldolase
Gene Name:rhmA
Enzyme Class:
Biological Properties
General Function:Involved in carbon-carbon lyase activity
Specific Function:Catalyzes the reversible retro-aldol cleavage of 2-keto- 3-deoxy-L-rhamnonate (KDR) to pyruvate and lactaldehyde. 2-keto-3- deoxy-L-mannonate, 2-keto-3-deoxy-L-lyxonate and 4-hydroxy-2- ketoheptane-1,7-dioate (HKHD) are also reasonably good substrates, although 2-keto-3-deoxy-L-rhamnonate is likely to be the physiological substrate
