“…All the erp coding sequences, including erpA, erpC, and erpP, are preceded by almost identical 5′-non-coding sequences, including binding sites for at least 3 distinct DNA-binding proteins (Babb et al, 2004. Co-regulation of erp genes on different cp32 plasmids suggests the existence of similar molecular mechanisms that could coordinate expression of genes encoding BbCRASP-3, -4, and -5 at the transcriptional level Babb et al, 2001;El-Hage and Stevenson, 2002;Babb et al, 2004Babb et al, , 2006.…”
