补充资料:多聚核糖核苷酸
分子式:
CAS号:

性质:又称PNP酶。系统名为多聚核糖核苷酸:正磷酸核苷酸基转移酶(polyribonucleotide:orthophosphate nucleotidyltransferase;EC 2.7.7.8)。系生物催化剂中的转换化学功能基因的酶类,通常可从大肠杆菌(Escherichia coli)或溶壁微球菌(Micrococcus lysodeikticus)中提取分离获得。酶活单位的定义随来源不同而异,从大肠杆菌来源的产品,其定义是:在15min时间内,pH值9.0,37℃条件下,消耗1.0μmol的腺嘌呤核苷二磷酸(ADP),并释放相同微摩尔的正磷酸为一个酶活力单位。主要是随机催化核糖核苷二磷酸聚合成为多聚核糖核苷酸的反应,并释出磷酸。主要应用于多聚鸟苷酸(polyguanylic acid)和其他多聚核苷酸的产品合成,以及作为人工合成的mRNA的片段的工具酶之一。
