Investigations with glutamic acid, methionine, and alanine have shown that n-amino acid utilization by lactic acid bacteria may be inhibited by specific antimetabolites (l-4). This has been taken to indicate that a conversion of o-amino acid substrate to the L form precedes its utilization, and that this process may be blocked by an appropriate inhibitor. Both Land n-alanines have been shown to...
