The DNA sequence of gamma-glutamyltranspeptidase gene of Bacillus subtilis (natto) plasmid pUH1.
The gamma-glutamyltranspeptidase (gamma-GTP) gene of Bacillus subtilis (natto) plasmid designated pUH1, which is responsible for polyglutamate production, has been cloned and the nucleotide sequence determined. The sequence contains a single open-reading frame stretching for 1260 bp with a relative molecular mass of 49,356. Putative -35 and -10 sequences, TTCAAA and TATTAT, were observed as the consensus sequence for the promoter recognized by the sigma 43 RNA polymerase of B. subtilis, and the ribosome binding site, the sequence of which was AACGAG, was complementary to the binding sequence of B. subtilis 16S rRNA except for one base. The amino acid sequence of the gene with the segment of putative protein C403 of staphylococcal plasmid pE194 indicates homology, whereas that with Escherichia coli and mammalian gamma-GTPs does not show any similarity at all.
