Rhodobacter capsulatus transketolase (Tkt) protein has been isolated from strain B10 by heparin affinity chromatography. Oligodeoxyribonucleotides (oligo) constructed as based on the amino-acid sequences were used for polymerase chain reaction (PCR) amplification on total genomic DNA. Southern hybridization with the PCR product as a probe allowed the isolation of a 5-kb PstI DNA fragment containing the structural Tkt-encoding gene (tktA) which was cloned and sequenced. The deduced tktA product of 671 aa (72815 Da) shares 59% identity with Rhodobacter sphaeroides Tkt.
