Biochemistry and genetics of microbial xylanases.
Xylanases are classified into two major families (10 or F and 11 or G) of glycosyl hydrolases. Both use ion pair catalytic mechanisms and both retain anomeric configuration following hydrolysis. Family 10 xylanases are larger, more complex and produce smaller oligosaccharides; Family 11 xylanases are more specific for xylan. Alkaline-active and extreme-thermophilic enzymes are of particular interest. Such xylanases are being commercialized for bleaching pulps and other applications.
