Bicarbonate concentration by Synechocystis PCC6803 : modulation of protein phosphorylation and inorganic carbon transport by glucose

摘要: The ability of the cyanobacterium Synechocystis PCC6803 to transport inorganic carbon in form bicarbonate rapidly decreased following a shift from bicarbonate-limited growth either excess supply or photoheterotrophic on glucose. Nonmetabolizable analogs glucose did not exert this effect. rate at which uptake declined was too rapid be accounted for by dilution activity culture and suggested that posttranslational modification may involved. Several proteins were unphosphorylated during became phosphorylated shifts high CO2 conditions growth. A similar alteration profile phosphopolypeptides observed into dark. changes protein phosphorylation blocked chloramphenicol rifampicin.
