Abstract

The almost complete purification of the previously reported DNA polymerase of chicken embryo is described; in the final isolation step the enrichment of the enzyme, which comprises about 0.01% of the protein extractable from 10-day-old embryos, is more than 9000-fold. The enzyme is a basic protein (pI = 9.15), of molecular weight about 27,000. It exhibits no nuclease activity, requires Mn(2+) ion for activity, and may contain Zn. It is very sensitive to oxidation.

摘要

本文描述了鸡胚中先前报道的DNA聚合酶几乎完全纯化的过程；在最终的分离步骤中，该酶（占10日龄胚胎可提取蛋白质的约0.01%）的富集倍数超过9000倍。该酶是一种碱性蛋白（pI = 9.15），分子量约为27000。它不具有核酸酶活性，活性需要Mn(2+)离子，可能还含有锌。它对氧化非常敏感。
