Abstract:
:Membrane vesicles were characterized for their ability to specifically bind [14C]glucose 6-phosphate. Membranes prepared from a strain carrying a ColE1 uhp hybrid plasmid showed significantly enhanced glucose 6-phosphate binding. It is hypothesized that glucose 6-phosphate binding to these membranes is due to a uhpR-directed, membrane-bound receptor which functions in regulation of the inducible uhpT gene product: the hexose phosphate permease.
