产品介绍蛋白酶K是一个稳定,高活性丝氨酸蛋白酶。从晶体和分子结构研究的证据表明这种酶属于枯草杆菌家族,带有活性催化位点催化三键(Asp39,His69 - Ser224)。它是在宽的的环境范围内保持稳定:pH值,缓冲盐,去垢剂(SDS),和温度。在0.1-0.5% SDS存在下,在分离DNA中,蛋白酶K保持活性,消化各种蛋白质和核酸酶。
生化机理Proteinase K is a stable and highly reactive serine protease. Evidence from crystal and molecular structure studies indicates the enzyme belongs to the subtilisin family with an active-site catalytic triad (Asp39-His69-Ser224). It is stable in a broad range of environments: pH, buffer salts, detergents (SDS), and temperature. In the presence of 0.1-0.5% SDS, proteinase K retains activity and will digest a variety of proteins and nucleases in DNA preparations without compromising the integrity of the isolated DNA.
