| Note | Formerly known as glycosyltransferase family GT36; Assigned to a GH family following a paper by Hidaka, Honda, Kitaoka, Nirasawa, Hayashi, Wakagi, Shoun and Fushinobu (Structure (Camb). 2004 Jun;12(6):937-947) (PMID: 15274915) that revealed the evolutionary, structural and mechanistic relationship of these phosphorylases with glycoside hydrolases of clan GH-L. |
