Abstract

Bacillus clausii TnrA transcription factor is required for global nitrogen regulation. In order to obtain an
overview of gene regulation by TnrA in B. clausii KSMK16, the entire genome of B. clausii was screened for
the consensus sequence, 5’-TGTNAN7TNACA-3’ known as the TnrA box, and 13 transcription units were
found containing a putative TnrA box. The TnrA targets identified in this study were tnrA, glnA, nrgA,
nasFDEB, puc genes, licT, the two operons of the oligopeptide ABC transporter, lytR, transcriptional regulator
of the Lrp/AsnC family, sodium-dependent transporter of SNF family, hyu genes and a biochemically
uncharacterized protein.
