3-1,4-Glycanase from Cellulomonas fimi
The 0-1,4-glycanase Cex of the gram-positive bacterium Cellulomonas fimi is a glycoprotein comprising a C-terminal cellulose-binding domain connected to an N-terminal catalytic domain by a linker containing only prolyl and threonyl (PT) residues. Cex is also glycosylated by Streptomyces lividans. The glycosylation of Cex produced in both C. fimi and S. lividans protects the enzyme from proteoly...
متن کاملMannan-degrading enzymes from Cellulomonas fimi.
The genes man26a and man2A from Cellulomonas fimi encode mannanase 26A (Man26A) and beta-mannosidase 2A (Man2A), respectively. Mature Man26A is a secreted, modular protein of 951 amino acids, comprising a catalytic module in family 26 of glycosyl hydrolases, an S-layer homology module, and two modules of unknown function. Exposure of Man26A produced by Escherichia coli to C. fimi protease gener...
متن کاملPurification and characterization of a thermostable cellobiohydrolase from Fomitopsis pinicola.
A screening for cellobiohydrolase (CBH) activity was performed and Fomitopsis pinicola KMJ812 was selected for further characterization as it produced a high level of CBH activity. An extracellular CBH was purified to homogeneity by sequential chromatography of F. pinicola culture supernatants. The molecular mass of the F. pinicola CBH was determined to be 64 kDa by SDS-PAGE and by size-exclusi...
متن کاملNucleotide sequence of the cellobiohydrolase gene from Trichoderma viride.
The filamentous fungus, Trichoderma viride, secretes large amounts of several cellulolytic enzymes (1). We report here the nucleotide sequence of the gene coding for exo-cellobiohydrolase (CBH), which accounts for more than 65% of the total cellulase content. This gene was isolated from a T. viride genomic library using a 30mer oligonucleotide based on the sequence of the reported CBHI gene of ...
متن کاملCellobiohydrolase Hydrolyzes Crystalline Cellulose on Hydrophobic Faces*
Biodegradation of plant biomass is a slow process in nature, and hydrolysis of cellulose is also widely considered to be a rate-limiting step in the proposed industrial process of converting lignocellulosic materials to biofuels. It is generally known that a team of enzymes including endo- and exocellulases as well as cellobiases are required to act synergistically to hydrolyze cellulose to glu...
