Fig. 3From: The MarR-like protein PchR (YvmB) regulates expression of genes involved in pulcherriminic acid biosynthesis and in the initiation of sporulation in Bacillus subtilis Involvement of YvmB CcpA as repressors in the control of yvmB expression. a, b and c) Expression of a pyvmB’-lacZ transcriptional fusion was compared in wild-type (strain BSAS108), ΔyvmB cells (strain BSAS109) and ΔccpA cells (strain BSAS153). Strains were grown in LB medium. Growth was monitored by measuring OD600: grey curves. β-galactosidase activity of the pyvmB’-lacZ fusion is indicated: black circles, in the wild-type; red squares, in ΔyvmB cells; blue triangles, in ΔccpA cells. Values are the means from at least four independent experimentsBack to article page
