UniProt entry for RNA polymerase sigma-E factor (sigE/spoIIGB)
-
SigE is synthesized as a precursor P31 that is proteolytically cleaved by SpoIIGA to yield the active sigma-29 factor
"Proteolytically cleaved in the N-terminus by SpoIIGA to yield the active peptide"
-
SigE contains a helix-turn-helix DNA-binding motif at residues 206-225
"DNA_BIND 206..225 /note="H-T-H motif""
-
SigE belongs to the sigma-70 factor family
"Belongs to the sigma-70 factor family"
-
Sigma factors are initiation factors that promote attachment of RNA polymerase to specific initiation sites and are then released
"Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released"
A developmental gene product of Bacillus subtilis homologous to the sigma factor of Escherichia coli
-
Original identification of sigE (spoIIGB) as a sigma factor homolog
"This gene encodes a polypeptide with a predicted relative molecular mass of 27,652 which contains a 65-amino acid region highly homologous to an internal part of the Escherichia coli sigma factor"
Sporulation-specific sigma factor sigma 29 of Bacillus subtilis is synthesized from a precursor protein, P31
-
Demonstrated that the mature sigma-29 factor is derived by proteolytic cleavage of a P31 precursor
"sigma 29, is synthesized as an inactive precursor (P31) and that its activation occurs by a developmentally regulated cleavage of 29 amino acids from the P31 amino terminus"
