Proteinase K

 

Proteinase K, a broad-spectrum serine protease, firstly was extracted and purified from Engyodontium album. Because it can degrade Keratin, so named proteinase K. The crystallization and molecular structure of Proteinase K indicate it belongs to subtilisin family, whose active site has a characteristic catalytic triple amino acid Asp39-His69-Ser224. Proteinase K has no significant substrate specificity, and main cleavage site is the peptide bond at the carboxyl end of the hydrophobic amino acid such as aliphatic or aromatic.


Proteinase K is derived from yeast based on the optimized gene of Engyodontium album by site-directed mutation. It is purified by chromatography process, and with calcium and glycerin as protective agents.
