UDP-glucose + phosphoglucomutase Saccharomyces cerevisiae underglucosylated phosphoglucomutase increases GlcPTase activity in vitro, this underglucosylated state is maximized when galactose is used as carbon source or following a heat shock in Saccharomyces cerevisiae cultures ?

UDP-glucose + phosphoglucomutase specific for UDP-glucose, the site affected in the GlcPTase reaction is not the enzymatic active site of phosphoglucomutase, underglucosylated forms of phosphoglucomutase obtained in response to heat shock and growth in media containing carbon sources other than glucose increase transfer in vitro GlcPTase assays and appear to reflect regulation of the GlcPTase activity Saccharomyces cerevisiae ?
