A 10.3 kbp Segment from nprB to argJ at the 102{degrees} Region of the Bacillus Subtilis Chromosome

Institut de Génétique et Microbiologie, URA CNRS 1354, Université Paris XI, Båtiment 409, 91405 Orsay Cedex, France ABSTRACT The approximately 10 kbp region encompassing nprB and argJ at 102° on the Bacillus subtilis chromosome was sequenced, revealing 12 ORFs, four known genes ( argJ, argC, ipi and nprB ) and two genes, yitY and yitS , whose products respectively display significant homology with L-gulono- -lactone oxidase of rat and dihydrofolate reductase of Staphylococcus aureus. The data also indicated that nprB mapped to a different position than previously published. 1 Author for correspondence: S. J. Seror. Tel: + 33 1 69 15 57 14. Fax: +33 1 69 15 78 08.
