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.

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.

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.

Methylenetetrahydrofolate reductase (MTHFR). 5,10-Methylenetetrahydrofolate is reduced to 5-methyltetrahydrofolate by methylenetetrahydrofolate reductase, a cytoplasmic, NAD(P)-dependent enzyme. 5-methyltetrahydrofolate is utilized by methionine synthase to convert homocysteine to methionine. The enzymatic mechanism is a ping-pong bi-bi mechanism, in which NAD(P)+ release precedes the binding of methylenetetrahydrofolate and the acceptor is free FAD. The family includes the 5,10-methylenetetrahydrofolate reductase EC:1.7.99.5 from prokaryotes and methylenetetrahydrofolate reductase EC: 1.5.1.20 from eukaryotes. The bacterial enzyme is a homotetramer and NADH is the preferred reductant while the eukaryotic enzyme is a homodimer and NADPH is the preferred reductant. In humans, there are several clinically significant mutations in MTHFR that result in hyperhomocysteinemia, which is a risk factor for the development of cardiovascular disease.

Dihydroorotate dehydrogenase (DHOD) class 1B FMN-binding domain. DHOD catalyzes the oxidation of (S)-dihydroorotate to orotate. This is the fourth step and the only redox reaction in the de novo biosynthesis of UMP, the precursor of all pyrimidine nucleotides. DHOD requires FMN as co-factor. DHOD divides into class 1 and class 2 based on their amino acid sequences and cellular location. Members of class 1 are cytosolic enzymes and multimers while class 2 enzymes are membrane associated and monomeric. The class 1 enzymes can be further divided into subtypes 1A and 1B which are homodimers and heterotetrameric proteins, respectively.
