title: Cloning and sequence analysis of the dimethylsulfoxide reductase structural gene from Rhodobacter capsulatus.
abstract: The dimethylsulfoxide reductase structural gene (dorA) of Rhodobacter capsulatus was cloned from a lambda expression library. The nucleotide sequence of the dorA gene was determined and it was found to encode a protein of 825 amino acids. Comparison of the deduced amino-acid sequence of DorA with N-terminal sequence of purified dimethylsulfoxide reductase from Rhodobacter capsulatus showed that the pre-protein possesses a 41-amino-acid N-terminal signal polypeptide. All of the conserved segments which have been described in bacterial enzymes which bind molybdopterin guanine dinucleotide (Berks, B.C., Ferguson, S.J., Moir, J.W.B. and Richardson, D.J. (1995) Biochim, Biophys. Acta 1232, 97-173) were identified in Rhodobacter capsulatus dimethylsulfoxide reductase.
