Abstract:
ppe2 gene is predicted to be present in operon with non pe/ppe genes, cobq1 and cobu as ppe2-cobq1-cobu. Thus, we were interested to investigate the role of ppe2 in operonic organization. We performed microscale thermophoresis (MST) experiment which revealed that PPE2 protein could bind to upstream DNA segments of ppe2-cobq1-cobu operon. Upstream region of ppe2 had shown promoter activity in β-gal assay. In this study, for the first time, a physical interaction between PPE2 protein and DNA fragment was reported, suggesting that PPE2 protein plays a role in the regulation of the putative ppe2-cobq1-cobu operon, via unknown mechanism.
