Expression and Regulation
Operons
Genes
atpI-atpB-atpE-atpF-atpH-atpA-atpG-atpD-atpC
Description
PubMed
Regulation
Rel dependent downregulation (Class I) during stringent response PubMed
the mRNA is processed between atpI and atpB by RNase Y, this requires the RicA-RicF-RicT complex PubMed
Regulatory mechanism
stringent response: negative regulation, in stringent response
