PHOSPHORIBULOKINASE FROM RHODOBACTER SPHEROIDES
OverviewOverview
The essential photosynthetic enzyme phosphoribulokinase (PRK) is, responsible for the conversion of ribulose 5-phosphate (Ru5P) to ribulose, 1,5-bisphosphate, the substrate for the CO2 fixing enzyme ribulose, 1,5-bisphosphate carboxylase/oxygenase (Rubisco). We have determined the, structure of the octameric bacterial form of PRK to a resolution of 2.5 A., The protein is folded into a seven-member mixed beta-sheet surrounded by, alpha-helices, giving the overall appearance of the nucleotide, monophosphate family of kinases. Homology with the nucleotide, monophosphate kinases suggests a number of amino acid residues that are, likely to be important in catalysis and suggests the roles of some amino, acid residues that have been mutated prior to the determination of the, structure. Further, ... [(full description)]
