Fingerprinting Trichoderma reesei Hydrolases in a Commercial Cellulase Preparation
- 373 Downloads
Polysaccharide degrading enzymes from commercial T. reesei broth have been subjected to “fingerprint” analysis by high-resolution 2-D gel electro-phoresis. Forty-five spots from 11 × 25 cm Pharmacia gels have been analyzed by LC-MS/MS and the resulting peptide sequences were compared to existing databases. Understanding the roles and relationships of compo-nent enzymes from the T. reesei cellulase system acting on complex sub-strates is key to the development of efficient artificial cellulase systems for the conversion of lignocellulosic biomass to sugars. These studies suggestfollow-on work comparing induced and noninduced T. reesei cells at the proteome level, which may elucidate substrate-specific gene regulation and response.
