L-methionine:2-oxo-acid aminotransferase

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 [1]. The enzyme from the plant Arabidopsis thaliana is also a part of the chain elongation pathway in the biosynthesis of methionine-derived glucosinolates [3].
