Members of the ICL/PEPM enzyme family catalyze either P-C or C-C bond formation/cleavage. Known members are phosphoenolpyruvate mutase (PEPM), phosphonopyruvate hydrolase (PPH), carboxyPEP mutase (CPEP mutase), oxaloacetate hydrolase (OAH), isocitrate lyase (ICL), and 2-methylisocitrate lyase (MICL). Isocitrate lyase (ICL) catalyzes the conversion of isocitrate to succinate and glyoxylate, the first committed step in the glyoxylate pathway. This carbon-conserving pathway is present in most prokaryotes, lower eukaryotes and plants, but has not been observed in vertebrates. PEP mutase (PEPM) turns phosphoenolpyruvate (PEP) into phosphonopyruvate (P-pyr), an important intermediate in the formation of organophosphonates, which function as antibiotics or play a role in pathogenesis or signaling. P-pyr can be hydrolyzed by phosphonopyruvate hydrolase (PPH) to from pyruvate and phosphate. Oxaloacetate acetylhydrolase (OAH) catalyzes the hydrolytic cleavage of oxaloacetate to form acetate and oxalate, an important pathway to produce oxalate in filamentous fungi. 2-methylisocitrate lyase (MICL) cleaves 2-methylisocitrate to pyruvate and succinate, part of the methylcitrate cycle for the alpha-oxidation of propionate.

methylisocitrate lyase; Members of this family are methylisocitrate lyase, also called (2S,3R)-3-hydroxybutane-1,2,3-tricarboxylate pyruvate-lyase. This enzyme acts in propionate metabolism. It cleaves a carbon-carbon bond to convert 2-methylisocitrate to pyruvate plus succinate. Some members of this family have been annotated, incorrectly it seems, as the related protein carboxyphosphoenolpyruvate phosphomutase, which is involved in synthesizing the antibiotic bialaphos in Streptomyces hygroscopicus.

phosphoenolpyruvate mutase; This family consists of examples of phosphoenolpyruvate phosphomutase, an enzyme that creates a C-P bond as the first step in the biosynthesis of natural products including antibiotics like bialaphos and phosphonothricin in Streptomyces species, phosphonate-modified molecules such as the polysaccharide B of Bacteroides fragilis, the phosphonolipids of Tetrahymena pyroformis, the glycosylinositolphospholipids of Trypanosoma cruzi. This gene generally occurs in prokaryotic organisms adjacent to the gene for phosphonopyruvate decarboxylase (aepY). Since the PEP phosphomutase reaction favors the substrate PEP energetically, the decarboxylase is required to drive the reaction in the direction of phosphonate production. Most often an aminotansferase (aepZ) is also present which leads to the production of the most common phosphonate compound, 2-aminoethylphosphonate (AEP). A closely related enzyme, phosphonopyruvate hydrolase from Variovorax sp. Pal2, is excluded from this model.
