| Abstract: | The nucleotide sequence for the Rhodobacter sphaeroides form II ribulose 1,5-bisphosphate carboxylase/oxygenase was determined. The deduced product is highly homologous with the form II-like enzyme of Rhodospirillum rubrum , but appears to be more distantly related to the large subunit of the L8S8 enzyme found in autotrophic bacteria, cyanobacteria and higher plants. Several regions highly conserved among L8S8 and LX enzymes correspond with regions previously implicated in catalytic activity and subunit interactions. An imperfect palindrome and a stem loop structure were identified in the 5' and 3' flanking sequences, respectively, of R. sphaeroides rbpL . |
