beta-Glucosidase in cellulosome of the anaerobic fungus Piromyces sp. strain E2 is a family 3 glycoside hydrolase.
The cellulosomes of anaerobic fungi convert crystalline cellulose solely into glucose, in contrast with bacterial cellulosomes which produce cellobiose. Previously, a beta-glucosidase was identified in the cellulosome of Piromyces sp. strain E2 by zymogram analysis, which represented approx. 25% of the extracellular beta-glucosidase activity. To identify the component in the fungal cellulosome ...
متن کاملAdsorption characteristics of cellulolytic enzymes from the anaerobic fungus Piromyces sp. strain E2 on microcrystalline cellulose.
Characteristics of the cellulolytic system of the anaerobic fungus Piromyces sp. strain E2 with respect to adsorption onto microcrystalline cellulose were examined. Cellulolytic enzymes were separated by gel filtration chromatography into a high-molecular-mass complex with an apparent mass of approximately 1,200 to 1,400 kDa and proteins of lower molecular weights. Adsorption of cellulolytic en...
متن کاملAn intron-containing glycoside hydrolase family 9 cellulase gene encodes the dominant 90 kDa component of the cellulosome of the anaerobic fungus Piromyces sp. strain E2.
The cellulosome produced by Piromyces sp. strain E2 during growth on filter paper was purified by using an optimized cellulose-affinity method consisting of steps of EDTA washing of the cellulose-bound protein followed by elution with water. Three dominant proteins were identified in the cellulosome preparation, with molecular masses of 55, 80 and 90 kDa. Treatment of cellulose-bound cellulosom...
متن کاملCytosolic enzymes with a mitochondrial ancestry from the anaerobic chytrid Piromyces sp. E2.
The anaerobic chytrid Piromyces sp. E2 lacks mitochondria, but contains hydrogen-producing organelles, the hydrogenosomes. We are interested in how the adaptation to anaerobiosis influenced enzyme compartmentalization in this organism. Random sequencing of a cDNA library from Piromyces sp. E2 resulted in the isolation of cDNAs encoding malate dehydrogenase, aconitase and acetohydroxyacid reduct...
متن کاملAntitubercular activity of the fungus Gliocladium sp. MR41 strain
Tuberculosis (TB) is leading cause of death worldwide from infectious diseases and its inadequate treatment has led to emergence of resistant strains. The emergence of these strains renders the search for new drugs for the treatment of TB. The aim of this study was the evaluation of the anti-TB activity of the extract from fungus Gliocladium sp. MR41, and bioassay-guided fractionation and ident...
