There was no discernible effect after incubating recombinant Anabaena Rubisco and carboxyarabinitol 1-phosphate with the product of the Anabaena rca gene. Since the unactivated cyanobacterial Rubisco is not readily inhibited by ribulose 1,5-bisphosphate and fallover is not observed, a genetic basis for the function of the Rubisco activase-like gene (rca) was sought. The monocistronic rca gene was inactivated in vivo and resulting mutant strains of A. variabilis were found to be incapable of… CONTINUE READING
