Isocitrate lyase (P28240)

Identification
NameIsocitrate lyase
Synonyms
  • ICL
  • Threo-D(S)-isocitrate glyoxylate-lyase
  • Isocitrase
  • Isocitratase
Gene NameICL1
Enzyme Class
Biological Properties
General FunctionInvolved in isocitrate lyase activity
Specific FunctionCatalyzes the formation of succinate and glyoxylate from isocitrate, a key step of the glyoxylate cycle, which operates as an anaplerotic route for replenishing the tricarboxylic acid cycle. Required for growth on ethanol or acetate, but dispensable when fermentable carbon sources are available. Acts also on 2- methylisocitrate
