GH36 family

The GH36 family glycosyl hydrolase is a family of catalytic domains of proteins possessing glycosyl hydrolase activities . Also includes domains homologous to them, possibly not possessing such activities. In total, about 1,100 proteins containing domains of the GH36 family are known, most of them belong to bacteria . Four enzymatic activities have been described for proteins of this family: α-galactosidase ( EC 3.2.1.22 ), α-N-acetylgalactosaminidase ( EC 3.2.1.49 ), stachyose synthase ( EC 2.4.1.67 ) and raffinose synthase ( EC 2.4.1.82 ). Together with the GH27 and GH31 families, the GH36 family forms the GH-D clan. Within the GH36 family, 11 main subfamilies are distinguished, which were proposed to be considered as independent GH36A-GH36K families due to the lack of monophyletic origin in the genes of the proteins of this family.
