Protease evolution in Streptomyces griseus. Discovery of a novel dimeric enzymes.


This report describes the cloning and sequencing of a novel protease gene derived from Streptomyces griseus. Also described is the heterologous expression of the gene in Bacillus subtilis and characterization of the gene product. The sprD gene encodes a prepro mature protease of 392 amino acids tentatively named S. griseus protease D (SGPD). A significant… (More)
