Abstract Thiocapsa roseopersicina, High Potential Iron Sulfur Pro­ tein (HIPIP), Phototrophic Bacteria High potential iron sulfur protein (HIPIP) from the purple sulfur bacterium Thiocapsa roseopersicina was isolated in the oxidized and reduced form by DEAE-and Sephadex column chromatography (best purity index A 282 nm red/A 385 nm red. = 3.78). The enzyme contains non-heme iron and acid-labile sulfide in an equimolar ratio. The enzyme shows no aconitase activity.

High potential iron sulfur protein (HIPIP) of the purple sulfur bacterium Chromatium warmingii was purified to homogeneity by ion exchange chromatography, gel filtration and ammonium sulfate fractionation. The acidic protein was isolated in the reduced form. The best purity index (A280/A388) obtained was 2.52, and 3.8 μmol of the protein was isolated out of 100 g wet cell material. The molecular weights estimated by sodium dodecylsulfate polyacrylamide gel electrophoresis and gel filtration through Sephacryl S-200 were 8 900 and 10 500, respec­tively. The protein has an isoelectric point at pH 3.6 for the reduced form and at pH 3.8 for the oxidized form, and a midpoint redox potential of +355 mV. One mol of HIPIP contains 4 mol nonheme iron and 4 mol acid-labile sulfur
