Glycoside hydrolase family 71. This family of glycoside hydrolases 71 (following the CAZY nomenclature) function as alpha-1,3-glucanases (mutanases, EC 3.2.1.59). They appear to have an endo-hydrolytic mode of enzymatic activity and bacterial members are investigated as candidates for the development of dental caries treatments.The member from fission yeast, endo-alpha-1,3-glucanase Agn1p, plays a vital role in daughter cell separation, while Agn2p has been associated with endolysis of the ascus wall.
Glycoside hydrolase families 71, 99, and related domains. This superfamily of glycoside hydrolases contains families GH71 and GH99 (following the CAZY nomenclature), as well as other members with undefined function and specificity.
Uncharacterized glycoside hydrolase family 99-like domain. This family of putative glycoside hydrolases resembles glycosyl hydrolase families 71 and 99 (following the CAZY nomenclature) and may share a similar catalytic site and mechanism.
Glycoside hydrolase family 99, an endo-alpha-1,2-mannosidase. This family of glycoside hydrolases 99 (following the CAZY nomenclature) includes endo-alpha-1,2-mannosidase (EC 3.2.1.130), which is an important membrane-associated eukaryotic enzyme involved in the maturation of N-linked glycans. Specifically, it cleaves mannoside linkages internal to N-linked glycan chains by hydrolyzing an alpha-1,2-mannosidic bond between a glucose-substituted mannose and the remainder of the chain. The biological function and significance of the soluble bacterial orthologs, which may have obtained the genes via horizontal transfer, is not clear.
