  • PubMed Abstract: 
  • Isocitrate lyase catalyses the first committed step of the carbon-conserving glyoxylate bypass, the Mg(2+)-dependent reversible cleavage of isocitrate into succinate and glyoxylate. This metabolic pathway is an inviting target for the control of a number of diseases, because the enzymes involved in this cycle have been identified in many pathogens including Mycobacterium leprae and Leishmania ...
