Description
PubMed
Regulation
repressed by Rok-DnaA PubMed
expression starts in the stationary phase PubMed
expression is heterogeneous in the population, this is mediated by AbrB, Rok, and Spo0A PubMed
Regulatory mechanism
Rok: repression, PubMed, in rok regulon
Abh: activation, PubMed, in abh regulon
DnaA: repression, Rok-DnaA PubMed, in dnaA regulon
YvrHb: activation, PubMed, in yvrHb regulon
AbrB: repression, PubMed, in abrB regulon
Additional information
the mRNA is very stable (> 15 min) PubMed
the amount of the mRNA is substantially decreased upon depletion of RNase Y PubMed
