text: An inhibitor to an inhibitor of these proteins contains a domain also found in sulfate transporters called the STAS domain.
full_question: An inhibitor to an inhibitor of these proteins contains a domain also found in sulfate transporters called the STAS domain. These proteins, are regulated by a “partner-switching” mechanism such as the Rsb system in which their inhibitor phosphorylates an alternate partner which in turn binds to one of these proteins and activates it upon dephosphorylation.Rsd inhibits the most common example of these proteins, which contains a binding site at region 1.1 in addition to the conserved 2.4 and 4.2 regions. These proteins are analagous to TFIIB [t f 2 b] and ATFB. The majority of cells contain one of these proteins known as the “housekeeping” example which has a mass 70 kDa. These molecules recognize the Pribnow box and with reacts with the core complex to form the RNA polymerase holoenzyme. For 10 points name these proteins which in bacteria to initiate transcription.
