Expression and regulation

• Operon: skfA-skfB-skfC-skfD-skfE-skfF-skfG-skfH PubMed

• Sigma factor: SigA PubMed

• Regulation:

• Regulatory mechanism:

• Additional information: Northern blotting during during phosphate limitation showed an intense 0.25 kb skfA-specific transcript, and a weaker 6.5 kb skfA-skfB-skfC-skfD-skfE-skfF-skfG-skfH transcript. The skfA transcript is stabilized by a stem-loop structure in the skfA-skfB intergenic region. PubMed
