  • Title: Purification and properties of collagenase from a Streptomyces species.
    Author: Endo A, Murakawa S, Shimizu H, Shiraishi Y.
    Journal: J Biochem; 1987 Jul; 102(1):163-70. PubMed ID: 2822678.
    Abstract:
    A collagenase active against native, insoluble collagen was isolated from the culture filtrate of a streptomycete which has been designated Streptomyces sp. C-51. Collagenase was produced by growing this strain in media containing gelatin. Purification by ammonium sulfate fractionation and chromatographies on DEAE-Toyopearl and DEAE-Cellulofine columns produced active enzyme which was free of contaminating proteins, including nonspecific proteinases, but which contained two active subspecies (I and II). Both subspecies were purified by preparative slab gel electrophoresis. The apparent molecular weights were 100,000 for the homogeneous fraction I and 90,000-110,000 for the microheterogeneous fraction II. These two subspecies were most active at pH 8-9, very similar in amino acid composition and immunologically identical. Some other properties of the Streptomyces C-51 collagenase were compared with those of Clostridium histolyticum collagenase. Substrate specificity, insensitivity to N-ethylmaleimide and diisopropyl fluorophosphate, and sensitivity to certain metal ion complexing agents were similar for the collagenases from both microorganisms.
