Glyco_10 Glycosyl hydrolase family 10

SMART accession number:	SM00633
Description:
Interpro abstract (IPR001000):	O-Glycosyl hydrolases (EC 3.2.1.) are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [(PUBMED:7624375), (PUBMED:8535779)]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site. Glycoside hydrolase family 10 comprises enzymes with a number of known activities; xylanase (EC 3.2.1.8); endo-1,3-beta-xylanase (EC 3.2.1.32); cellobiohydrolase (EC 3.2.1.91). These enzymes were formerly known as cellulase family F. The microbial degradation of cellulose and xylans requires several types of enzymes such as endoglucanases (EC 3.2.1.4), cellobiohydrolases (EC 3.2.1.91) (exoglucanases), or xylanases (EC 3.2.1.8) [(PUBMED:2252383), (PUBMED:1886523)]. Fungi and bacteria produces a spectrum of cellulolytic enzymes (cellulases) and xylanases which, on the basis of sequence similarities, can be classified into families. One of these families is known as the cellulase family F [(PUBMED:2806912)] or as the glycosyl hydrolases family 10 [(PUBMED:1747104)].
