第十二届国际癌症大会报告,分离血浆5′-核苷酸磷酸二酯酶的同工酶,对原发性和继发性肝癌有肯定的诊断价值。现将有关此酶的资料综述如下。概述 5′-核苷酸磷酸二酯酶(5′-nucleotide phosphodiesterase,以下简书5′-NPD)属水解酶类。系统名为寡核苷酸:5′-核苷酸水解酶(oligonucleate:5′-nucleotidohydrolase);国际生化协会酶学委员会分类编号:EC.3.1.4.1。 5′-NPD广泛分布于哺乳动物各组织, The 12th International Conference on Cancer reported that the isolation of isozymes of plasma 5’-nucleotide phosphodiesterase is of positive diagnostic value for primary and secondary liver cancer. The information on this enzyme is summarized below. Overview 5’-nucleotide phosphodiesterase (5’-NPD) is a class of hydrolases. The system name is oligonucleotide: 5’-nucleotide hydrolase (oligonucleate: 5’-nucleotidohydrolase); International Biochemical Society Enzymology Committee classification number: EC.3.1.4.1. 5′-NPD is widely distributed in mammalian tissues.
