  • sigma factors

  • [protein|360F48D576DE950DF79C1A2677B7A35A8D8CC30C|SigA]: sigma factor, [Pubmed|22229825], in [regulon|360F48D576DE950DF79C1A2677B7A35A8D8CC30C|SigA regulon]
  • regulation

  • expression increases at the onset of the stationary phase [pubmed|22229825]
  • the mRNA is destabilized upon interaction with the antitoxin RNA [gene|10A53E2465B5EAA307A099052FBBDF3B62857291|SR4] [pubmed|22229825]
  • regulatory mechanism

  • the mRNA is degraded by [protein|BAB297D18F94FFA67B8D12A684AB4D1BCDFB4981|RNase III], [protein|872CCB5A49C9000BD95E4B0472556D5F60F7D7A4|RNase Y] and [protein|0472A4346ADA1DC41C9D00E8F3222A0EBB76DFA8|RNase R], degradation is enhanced at higher temperature [pubmed|22229825]
  • Additional information

  • half-life of the mRNA: 15 min [pubmed|22229825]
  • upon heat shock, the mRNA refolds and is degraded by [protein|872CCB5A49C9000BD95E4B0472556D5F60F7D7A4|RNase Y] and [protein|3EB289D0F58A58C693AB588798EE66A731341999|RNase J1][pubmed|22229825]
