Abstract

Further studies of the transaminase responsible for the first committed step in alkaloid formation in Conium maculatum have shown the L-alanine: 5-ketooctanal transaminase to occur in both the mitochondria and chloroplast. Experiments suggest that these enzymes are the isoenzymes Transaminase A and B respectively previously isolated by the author. It is suggested that the chloroplast enzyme is normally responsible for alkaloid production.

摘要

进一步研究负责在 Conium maculatum 中生物碱形成第一步的转氨酶，表明 L-丙氨酸：5-酮辛醛转氨酶存在于线粒体和叶绿体中。实验表明，这些酶分别是作者先前分离的同工酶 Transaminase A 和 B。有人认为，叶绿体中的酶通常负责生物碱的产生。
