Fungal strains possessing xyloglucanase activity have been selected from the microorganisms degrading plant biomass deposited in the Russian National Collection of Industrial Microorganisms (VKPM). The thermophilic strains Sporotrichum thermophile VKPM F-972, Myceliophthora thermophila VKPM F-244, and Sporotrichum pruinosum VKPM F-235 produced extracellular(More)
Electrophoretically homogeneous proteolytic enzyme with molecular weight 31,500 and pI 3.75 was obtained from a culture medium of Streptomyces 771 by chromatography on N-benzyl chitin adsorbent, subsequent chromatography on CM-cellulose, and preparative isofocusing and chromatography on Sephadex G-75. The enzyme hydrolyzes(More)
A xyloglucanase of the GH74 family was identified in the thermophilic fungus strain Myceliophthora thermophila VKPM F-244, and its gene sequence was optimized for cloning and expression in Pichia pastoris. The recombinant xyloglucanase MtXgh74 exhibited the highest activity toward tamarind seed xyloglucan with a K M value of 0.51 ± 0.06 mg/mL. The(More)
