• Operon:
  • yxbB-yxbA-yxnB-asnH-yxaM PubMed
  • yxbB-yxbA-yxnB PubMed

• Expression browser: yxbB PubMed

• Sigma factor: SigA PubMed

• Regulation:
  • repressed by glucose (8-fold) PubMed
  • repressed during growth in the presence of branched chain amino acids (CodY) PubMed
  • repressed during logrithmic growth (AbrB) PubMed

• Regulatory mechanism:
  • CodY: transcription repression PubMed
  • AbrB: transcription repression PubMed

• Additional information:
  • the tricistronic yxbB-yxbA-yxnB transcript is extremely stable, and stability is mediated by a 5'-proximal long sequence triplication preceding the yxbB open reading frame PubMed
  • The mRNA has a long 5' leader region. This may indicate RNA-based regulation PubMed
  • the amount of the mRNA is substantially decreased upon depletion of RNase Y PubMed
