title: [Physicochemical properties of a fibrinolytic enzyme from Streptomyces thermovulgaris culture broth].
abstract: Some properties of fibrinolytic enzyme from cultural fluid of Streptomyces thermovulgaris have been studied. The molecule of enzyme has been shown to consist of one polypeptide chain with molecular mass 28000 dalton, pi = 7.45-7.6. The amino acid composition of protein is determined, the protein does not contain cysteine residues. The enzyme is not thermostable, and Ca2+ ion does not exert stabilized influence. In opposition to diisopropylfluorophosphate, phenylmethylsulfonyl fluoride does not inhibit the enzyme activity.
