GLG2 (YJL137C, P47011) notes

Glycogenin-2, GT8 (EC 2.4.1.186). Redundant with GLG1. Module: glycogen_metabolism_fungal.

• In vitro primers for glycogen synthase PMID:8524228
• "In Glg2p, mutation of both Tyr230 and Tyr232 is necessary to suppress self-glucosylation of purified protein in vitro" PMID:8900126
• Still transfers to exogenous acceptor: "The mutant protein is still capable of transferring glucose to an exogeneous acceptor, n-dodecyl beta-D-maltoside" PMID:8900126
• Covalently in glycogen: "Glg2p was shown to be associated with carbohydrate in vivo and was released from the high molecular weight glycogen fraction by treatment with alpha-amylase" PMID:8900126
• MS: "glucosyl residues were attached to both Tyr232 and Tyr230 within the same peptide" PMID:15479227
