“…Despite the inhibition of Protox by these compounds in intact plants, the product of the enzyme, Proto IX, accumulates (Sato et al, 1987b;Sandmann and Bö ger, 1988;Becerril and Duke, 1989;Sherman et al, 1991). The uniqueness and complexity of the mechanism of Protox inhibitors is illustrated in the accumulation of Proto IX.…”

Porphyrin accumulation in excised cucumber cotyledons (Cucumis sativus L.) treated with a N-phenylimide S-23142 (N-[4-chloro-2-fluoro-5-propargyloxyphenyl]-3,4,5,6-tetrahydrophthalimide) and a diphenylether acifluorfen-ethyl (ethyl-5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitro benzoic acid) was studied. Most of the accumulated porphyrins were found in the membrane fractions of 6,000g and 30,000g pellets, forming a complex with a membrane polypeptide. The complex was solubilized with 1% n-dodecyl f-D-maltoside and its molecular mass was estimated to be 63,000 and 66,000 daltons by sodium dodecyl sulfatepolyacrylamide gel electrophoresis and gel permeation high performance liquid chromatography (HPLC), respectively. The polypeptide also existed in untreated cotyledons but had little protoporphyrin IX. The complex was also formed in vitro by mixing the 30,000g pellets from untreated cotyledons and authentic protoporphyrin IX. However, protoporphyrin IX formed the complex specifically with the 63,000 dalton polypeptide and not with the other proteins both in vivo and in vitro. At least four fluorescent porphyrins, including protoporphyrin IX, were found in the acetone extract of the cotyledons by HPLC using a reversed phase column. Protoporphyrin IX was one of the two porphyrins that formed the complex. These results suggest that S-23142 and acifluorfenethyl enhance the accumulation of protoporphyrin IX, which forms the complex with the membrane protein.
