Effects of a thiol-dependent serine proteinase of Bacillus intermedius on peptide substrates and insulin B-chain were studied. The enzyme preferably splits peptide bonds formed by carboxyl groups of hydrophobic amino acids. ...

Alkaline phosphatases and serine proteinases have been isolated from the culture liquid of streptomycin-resistant strains of Bacillus intermedius using ion-exchange and affinity chromatography and FPLC. Substrate blotting ...

The results on research of affection "in vitro" of preparate of thiol-dependent serine proteinase from B. intermedius on time of formation and dissolvation of the clots formed from plasma rat blood.
