The decarboxylations of uroporphyrinogens I and III and of heptacarboxylic, hexacarboxylic and pentacarboxylic porphyrinogens III by rat liver uroporphyrinogen decarboxylase were compared, and the results suggest that the removal of the first carboxy group from uroporphyrinogen III is a more rapid step than that from isomer I or the other substrates investigated.
比较了大鼠肝脏尿卟啉原脱羧酶对尿卟啉原I和III以及七羧酸、六羧酸和五羧酸卟啉原III的脱羧作用,结果表明,尿卟啉原III中第一个羧基的去除比异构体I或其他所研究底物中的相应步骤更快。
