A preparation is described through which large quantities of pure, active cytochrome b6/f complex can be isolated from spinach chloroplasts. The resulting complex is at least 90% pure with respect to the maximum content of redox centers, consists of four polypeptides according to polyacrylamide gel electrophoresis, and lacks both ferredoxin: NADP+ oxidoreductase and the high molecular weight form of cytochrome f seen in some other preparations. The complex contains 2 mol b6 and 2 atoms of… CONTINUE READING
