We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| + | [[http://www.uniprot.org/uniprot/DKSA_ECOLI DKSA_ECOLI]] Transcription factor that acts by binding directly to the RNA polymerase (RNAP). Required for negative regulation of rRNA expression and positive regulation of several amino acid biosynthesis promoters. Also required for regulation of fis expression. Binding to RNAP disrupts interaction of RNAP with DNA, inhibits formation of initiation complexes, and amplifies effects of ppGpp and the initiating NTP on rRNA transcription. Inhibits transcript elongation, exonucleolytic RNA cleavage and pyrophosphorolysis, and increases intrinsic termination. Also involved, with RecN, in repair of DNA double-strand breaks.<ref>PMID:15294157</ref> <ref>PMID:15948952</ref> <ref>PMID:16885445</ref> <ref>PMID:22210857</ref> <ref>PMID:15294156</ref> | ||
