abstract：:The gene encoding sigmaD, sigD, is transcribed from two promoter regions, the fla/che promoter region in front of the fla/che operon and PsigD directly in front of sigD. If sigmaD is translated from transcripts originating from PsigD, the cell is unable to express motility functions but synthesizes autolysins. Therefo...
