SPLITTING OF
-CAPROLACTAM AND OTHER LACTAMS BY BACTERIA
Basic Research Laboratories, Toyo Rayon Co., Ltd. Tebiro, Kamakura
-Caprolactam-utilizing bacteria split
-caprolactam,
-valerolactam and
-butyrolactam, and produce the
-amino acids corresponding to them. This activity is lost when cells are grown on 6-amino-caproic acid or ammonium adipate, and reappears when cells are incubated with either
-caprolactam or
-valerolactam as the sole major organic nutrient. Chloramphenicol inhibits this adaptation. The enzyme splitting those lactams is one and the same. It may be called "lactam-splitting enzyme". But attempts to demonstrate the enzymic activity in a cell-free system has not yet been successful.
