Regulation of Phosphotransferase Activity of Hexokinase 2 from Saccharomyces cerevisiae by Modification at Serine-14

Isoenzyme 2 of hexokinase functions in sugar sensing and glucose repression in Saccharomyces cerevisiae. The degree of in vivo phosphorylation of hexokinase 2 at serine-14 is inversely related to the extracellular glucose concentration [Vojtek, A. B., and Fraenkel, D. G. (1990) Eur. J. Biochem. 190,...
