[[http://www.uniprot.org/uniprot/WHIB1_MYCTU WHIB1_MYCTU]] Acts as a transcriptional repressor, inhibiting expression in vitro. Probably redox-responsive. The apo- but not holo-form binds to its own promoter as well as that of groEL2. Oxidized apo-form and nitrosylated holo-form also bind DNA. The apo-form has been shown to act as a protein disulfide reductase (PubMed:17157031) (PubMed:19016840), but also not to act as a protein disulfide reductase (PubMed:20929442).<ref>PMID:17157031</ref> <ref>PMID:19016840</ref> <ref>PMID:20929442</ref> <ref>PMID:22464736</ref> [[http://www.uniprot.org/uniprot/SIGA_MYCTU SIGA_MYCTU]] Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the primary sigma factor during exponential growth (Probable).<ref>PMID:12354223</ref> <ref>PMID:20729364</ref> <ref>PMID:22570422</ref>
