    Abstract

    The nucleotide sequence was determined of a 3211 nucleotide pair EcoRI-PvuII DNA fragment containing the tms and prs genes as well as a part of the ctc gene of Bacillus subtilis. The prs gene encodes phosphoribosylpyrophosphate (PRPP) synthetase, whereas the functioning of the tms and ctc gene products remains to be established. The prs gene contains an open reading frame of 317 codons resulting in a subunit Mr of 34828. An open reading frame comprising the tms gene contained 456 codons resulting in a putative translation product with an Mr of 49,554. Comparison of the deduced B. subtilis PRPP synthetase amino acid sequence with PRPP synthetases from Escherichia coli and rat liver showed extensive similarity. The deduced Tms amino acid sequence was found to be 43% similar to the deduced amino acid sequence of ecourfl, a gene of E. coli with unknown function.
