Enzyme Information
| 2.6.1.88 |
Methionine transaminase.
based on mapping to UniProt P77806
L-methionine + a 2-oxo acid = 2-oxo-4-methylthiobutanoate + an L-amino acid.
-!- The enzyme is most active with L-methionine. -!- It participates in the L-methionine salvage pathway from S-methyl- 5'-thioadenosine, a by-product of polyamine biosynthesis. -!- The enzyme from the bacterium Klebsiella pneumoniae can use several different amino acids as amino donor, with aromatic amino acids being the most effective. -!- The enzyme from the plant Arabidopsis thaliana is also a part of the chain elongation pathway in the biosynthesis of methionine-derived glucosinolates.
