Abstract
Enzyme activities of the transaminative pathway of cysteine metabolism in various rat tissues were examined. Liver was found the most active tissue, followed by kidney and heart. Liver and kidney were more pronounced in mercaptopyruvate sulfurtransferase activity than in cysteine transaminase activity; heart was more active in the latter. Red blood cells, which have pronounced sulfurtransferase activity, exhibited no transaminase activity, indicating the pathway is negligible in this tissue.
摘要
对大鼠各种组织中半胱氨酸代谢的转氨途径的酶活性进行了检测。发现肝脏是活性最高的组织，其次是肾脏和心脏。肝脏和肾脏中巯基丙酮酸硫转移酶的活性比半胱氨酸转氨酶的活性更显著；心脏中后者的活性更高。具有显著硫转移酶活性的红细胞没有表现出转氨酶活性，表明该途径在该组织中可忽略不计。
