Abstract:
:Primer extension analysis of transcripts of the Bacillus subtilis autolysin (cwlB) operon indicated that SigD-dependent transcripts from the Pd promoter are missing in the degU32(Hy) and degS200 (Hy) mutants. The degU32(Hy) mutation caused a 99% reduction in the expression of a sigD-lacZ translational fusion gene constructed in the B. subtilis chromosome. The phosphorylated form of the DegU protein seems to be a regulator for expression of the sigD gene.
