>TIGR00713 hemL glutamate-1-semialdehyde-2,1-aminomutase; InterPro: IPR004639 Tetrapyrroles are large macrocyclic compounds derived from a common biosynthetic pathway . The end-product, uroporphyrinogen III, is used to synthesise a number of important molecules, including vitamin B12, haem, sirohaem, chlorophyll, coenzyme F430 and phytochromobilin . The first stage in tetrapyrrole synthesis is the synthesis of 5-aminoaevulinic acid ALA via two possible routes: (1) condensation of succinyl CoA and glycine (C4 pathway) using ALA synthase (2.3.1.37 from EC), or (2) decarboxylation of glutamate (C5 pathway) via three different enzymes, glutamyl-tRNA synthetase (6.1.1.17 from EC) to charge a tRNA with glutamate, glutamyl-tRNA reductase (1.2.1.70 from EC) to reduce glutamyl-tRNA to glutamate-1-semialdehyde (GSA), and GSA aminotransferase (5.4.3.8 from EC) to catalyse a transamination reaction to produce ALA. The second stage is to convert ALA to uroporphyrinogen III, the first macrocyclic tetrapyrrolic structure in the pathway. This is achieved by the action of three enzymes in one common pathway: porphobilinogen (PBG) synthase (or ALA dehydratase, 4.2.1.24 from EC) to condense two ALA molecules to generate porphobilinogen; hydroxymethylbilane synthase (or PBG deaminase, 2.5.1.61 from EC) to polymerise four PBG molecules into preuroporphyrinogen (tetrapyrrole structure); and uroporphyrinogen III synthase (4.2.1.75 from EC) to link two pyrrole units together (rings A and D) to yield uroporphyrinogen III. Uroporphyrinogen III is the first branch point of the pathway. To synthesise cobalamin (vitamin B12), sirohaem, and coenzyme F430, uroporphyrinogen III needs to be converted into precorrin-2 by the action of uroporphyrinogen III methyltransferase (2.1.1.107 from EC). To synthesise haem and chlorophyll, uroporphyrinogen III needs to be decarboxylated into coproporphyrinogen III by the action of uroporphyrinogen III decarboxylase (4.1.1.37 from EC) . This entry represents glutamate-1-semialdehyde (GSA) aminotransferase (5.4.3.8 from EC), which catalyse a transamination reaction to produce 5-aminoaevulinic acid during the first stage of tetrapyrrole biosynthesis by the C5 pathway , . This enzyme has a high degree of similarity to amino acid transaminases, and is classed as a class III aminotransferase.; GO: 0042286 glutamate-1-semialdehyde 21-aminomutase activity, 0033014 tetrapyrrole biosynthetic process.
