Expression and regulation
- Regulation: repressed by glucose (33-fold) PubMed
- 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
