In enzymology, a glutamate-1-semialdehyde 2,1-aminomutase (EC 5.4.3.8) is an enzyme that catalyzes the chemical reaction
- L-glutamate 1-semialdehyde 5-aminolevulinate
Hence, this enzyme has one substrate, L-glutamate-1-semialdehyde, and one product, 5-aminolevulinate.
This enzyme belongs to the family of isomerases, specifically those intramolecular transferases transferring amino groups. The systematic name of this enzyme class is (S)-4-amino-5-oxopentanoate 4,5-aminomutase. This enzyme is also called glutamate-1-semialdehyde aminotransferase. This enzyme participates in porphyrin and chlorophyll biosynthesis. It employs one cofactor, pyridoxal phosphate.
Structural studies
[edit]As of late 2007, 10 structures have been solved for this class of enzymes, with PDB accession codes 2CFB, 2E7U, 2EPJ, 2GSA, 2HOY, 2HOZ, 2HP1, 2HP2, 3GSB, and 4GSA.
