초록
PpsR from the facultative photohetrotroph Rhodobacter sphaeroides is involved in repression of photo system gene expression. SDS-PAGE analysis showed that some portion of PpsR is oxidized so that intra- or inter-disulfide bond is formed between the two cysteins in each subunit. The disulfide bond was reduced by dithiothreitol and the binding activity to puc promoter region was increased.(omitted)
