human glycogenin during its reaction cycle shows a dynamic conformational switch between ground and active states mediated by the sugar donor UDP-glucose. This switch includes the ordering of a polypeptide stretch containing Tyr195, and major movement of an approximately 30-residue lid segment covering the active site. The rearranged lid guides the nascent maltosaccharide chain into the active site in either an intra- or intersubunit mode dependent upon chain length and steric factors and positions the donor and acceptor sugar groups for catalysis.

OsGGT-gene expression increases in FR13A (a submergence-tolerant cultivar, Indica) during submergence but decreases in IR42 (submergence-intolerant cultivar, Indica). The expression of the OsGGT gene in FR13A is induced by salicylic acid and benzyladenine. The accumulation of OsGGT mRNA in FR13A also increases in response to ethylene, gibberellin, abscisic acid, drought and salt treatment, but methyl jasmonate treatment and cold stress have no effect on expression. OsGGT gene can be related to submergence stress and associated with a general defensive response to various environmental stresses
