RNA polymerase sigma factor, ECF subfamily, SigC; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are usually held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis; this sigma factor does not seem to have a cognate anti-sigma factor however. It has been suggested that the sigma domains 2 and 4 may interact via polar residues in this protein to autoregulate. Positively regulates expression of a small regulon [...]

Probable alternative RNA polymerase sigma-D factor SigD; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis.

Hypothetical alanine rich protein; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor SigM. ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut extracytoplasmically (site-1 protease, S1P), then within the membrane itself (site-2 protease, S2P, Rip1), while cytoplasmic proteases finish degr [...]

Alternative RNA polymerase sigma factor SigK; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis. Sigma-K controls genes such as mpt70 and mpt83.

Conserved protein; Rv3909, (MTCY15F10.02c), len: 802 aa. Conserved protein, equivalent to Q9CCY0|ML2699 putative secreted protein from Mycobacterium leprae (797 aa) FASTA scores: opt: 3777, E(): 8.8e-206, (72.35% identity in 803 aa overlap). Note that the N-terminal end is highly similar to Q50196|L222-ORF7 (286 aa), FASTA scores: opt: 1213, E(): 2.7e-61, (71.75% identity in 255 aa overlap); and the C-terminal end is highly similar to Q50197|L222-ORF8 also from Mycobacterium leprae (512 aa) FASTA scores: opt: 2375,E(): 9.9e-127, (71.8% identity in 518 aa overlap). Shows some similarity [...]

Possible alternative RNA polymerase sigma factor SigI; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor until released, although no anti-sigma factor is known for this protein (By similarity).

Probable alternative RNA polymerase sigma factor (fragment) SigJ; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released, although no anti- sigma factor is known for this protein (By similarity). Regulates the promoter of SigI, may not be autoregulated.

Probable alternative RNA polymerase sigma factor SigG (RNA polymerase ECF type sigma factor); Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor until released, although no anti-sigma factor is known for this protein. May be involved in host intracellular survival after infection (strains H37Rv and CDC 1551). A role in the SOS response is controversial; it has been seen in strain CDC 1551 but not i [...]
