| + | MGL catalyzes the gamma-elimination of L-methionine and its derivatives as well as the beta-elimination of L-cysteine and its analogs. These reactions yield alpha-keto acids and thiols. The mechanism of chemical conversion of amino acids includes numerous reaction intermediates. The detailed analysis of MGL interaction with glycine, L-alanine, L-norvaline and L-cycloserine was performed by pre-steady-state stopped-flow kinetics. The structure of side chains of the amino acids is important both for their binding with enzyme and for the stability of the external aldimine and ketimine intermediates. X-ray structure of MGL-L-cycloserine complex has been solved at 1.6 A resolution. The structure models ketimine intermediate of physiological reaction. The results elucidate the mechanisms of the intermediates interconversion at the stages of external aldimine and ketimine formation. | ||
