Abstract

Streptomyces griseus trypsin (E.C.3.4.21.4) is one of the major extracellular proteinase, which is secreted by S. griseus. The gene encoding S. griseus trypsin was isolated from a S. griseus genomic library by using a synthetic oligonucleotide probe. Fragments containing the gene for S. griseus trypsin were characterized by hybridization and demonstration of proteolytic activity in S. lividans. Deduced amino acid sequence from the nucleotide sequence suggests that S. griseus trypsin is produced as a precursor, consisting of three portions; an amino-terminal pre sequence (32 amino acid residues), a pro sequence (4 residues), and the mature trypsin. The S. griseus trypsin consists of 223 amino acids with a computed molecular weight of 23,112. The existence of proline at the pro and mature junction suggests that the processing of S. griseus trypsin is non-autocatalytic.
