Bacterial cellulases and xylanases
Although this review focusses primarily on bacterial cellulases and xylanases, there is considerable overlap in the molecular biology and biochemistry of prokaryotic and fungal forms of these enzymes. Therefore, fungal plant cell wall hydrolases are discussed where comparisons with the corresponding bacterial enzymes are important. Cellulases and xylanases encompass a collection of enzymes whos...
متن کاملNatural diversity of cellulases, xylanases, and chitinases in bacteria
BACKGROUND Glycoside hydrolases (GH) targeting cellulose, xylan, and chitin are common in the bacterial genomes that have been sequenced. Little is known, however, about the architecture of multi-domain and multi-activity glycoside hydrolases. In these enzymes, combined catalytic domains act synergistically and thus display overall improved catalytic efficiency, making these proteins of high in...
متن کاملBacterial xylanases: biology to biotechnology
In this review, a comprehensive discussion exclusively on bacterial xylanases; their gene organization; different factors and conditions affecting enzyme yield and activity; and their commercial application have been deliberated in the light of recent research findings and extensive information mining. Improved understanding of biological properties and genetics of bacterial xylanase will enabl...
متن کاملBiotechnological applications of bacterial cellulases
Cellulases have numerous applications in several industries, including biofuel production, food and feed industry, brewing, pulp and paper, textile, laundry, and agriculture.Cellulosedegrading bacteria are widely spread in nature, being isolated from quite different environments. Cellulose degradation is the result of a synergic process between an endoglucanase, an exoglucanase and a,β-glucosid...
متن کاملMonocentric and polycentric anaerobic fungi produce structurally related cellulases and xylanases.
Cellulase and xylanase cDNAs were isolated from a cDNA library of the polycentric anaerobic fungus Orpinomyces sp. strain PC-2 constructed in Escherichia coli. The cellulase cDNA (celB) was 1.8 kb long with an open reading frame (ORF) coding for a polypeptide of 471 amino acids, and the xylanase cDNA (xynA) was 1.2 kb long with an ORF encoding a polypeptide of 362 amino acids. Single transcript...
