Description
Regulation
expression is reduced in a SigV mutant PubMed
the mRNA is processed between dltX and dltA by RNase Y, this requires the RicA-RicF-RicT complex PubMed
Regulatory mechanism
YvrHb: activation, PubMed, in yvrHb regulon
Spo0A: repression, PubMed, in spo0A regulon
stringent response: negative regulation, in stringent response
Sigma factors
SigD: sigma factor, PubMed, in sigD regulon
SigM: sigma factor, PubMed, in sigM regulon
SigX: sigma factor, PubMed, in sigX regulon
SigV: sigma factor, PubMed, in sigV regulon
