摘要

Kinetic experiments with 3-methylaspartase, using aspartic, 3-methylaspartic, and 3- ethylaspartic acid and the appropriate C-3 deuteriated isotopomers as substrates, reveal that C (3)–H bond cleavage is partially rate-limiting for 3-methylaspartic acid, much less rate- limiting for 3-ethylaspartic acid, and not rate-
