SigB, an RNA polymerase sigma factor required for osmoprotection and proper differentiation of Streptomyces coelicolor.

Molecular microbiology - 1 Oct 2001

Abstract excerpt

A gene (sigB) encoding an alternative sigma factor sigmaB in Streptomyces coelicolor A3(2) was isolated and characterized. It encodes a polypeptide of 281 amino acids (31 546 Da) and is highly homologous to Bacillus subtilis sigmaB. The sigB coding region is preceded by four open reading frames (ORFs): dpsA, orfA, rsbB and rsbA in sequential order. RNA analyses revealed that rsbB, rsbA and sigB constitute an...
