The IbpB thermometer is an RNA thermometer element found in the ibpAB operon. The operon contains two heat-shock genes, encoding inclusion body binding proteins A and B (IbpA/B), and is the most drastically upregulated operon under heat-shock in Escherichia coli. IbpA is regulated by a ROSE element found in its 5' UTR, while IbpB has its own heat-sensitive cis-regulatory element. The activity of this thermoregulator was confirmed in vitro but was not found in vivo, suggesting more complicated operon regulation exists in bacterial cells.

  • The IbpB thermometer is an RNA thermometer element found in the ibpAB operon. The operon contains two heat-shock genes, encoding inclusion body binding proteins A and B (IbpA/B), and is the most drastically upregulated operon under heat-shock in Escherichia coli. IbpA is regulated by a ROSE element found in its 5' UTR, while IbpB has its own heat-sensitive cis-regulatory element. The activity of this thermoregulator was confirmed in vitro but was not found in vivo, suggesting more complicated operon regulation exists in bacterial cells. (en)
  • Termometr IbpB – termometr RNA obecny w obrębie operonu ibpAB. Operon ten zawiera dwa geny związane z , kodującym białka IbpA i IbpB (inclusion body binding proteins A and B). Jest podlegającym największej operonem podczas szoku cieplnego u bakterii Escherichia coli. IbpA regulowany jest poprzez element ROSE (repression of heat shock gene expression element) leżący w regionie 5'-flankującym , podczas gdy IbpB posiada swój własny wrażliwy na zmiany temperatury element związany z cis-regulacją. Aktywność tego termoregulatora została potwierdzona in vitro, nie znaleziono jej jednak in vivo. Sugeruje to istnienie w bakterii bardziej skomplikowanego operonu. (pl)
