The redox-sensitive R-loop of the carbon control protein SbtB contributes to the regulation of the cyanobacterial CCM
Abstract SbtB is a PII-like protein that regulates the carbon-concentrating mechanism (CCM) in cyanobacteria.SbtB proteins can bind many adenyl nucleotides and possess a characteristic C-terminal redox sensitive loop (R-loop) that forms a Course a pied - Enfant - Chaussures - Trail disulfide bridge in response to the diurnal state of the cell.SbtBs
