Treatment of bovine heart bci complex with ethoxyformic anhydride (EFA), which is known to modify amino acid residues covalently (preferentially histidine residues), inhibits electron transfer and has an effect on the EPR spectra of the Rieske cluster comparable to that observed upon addition of stigmatellin, that is, a decrease in rhombicity (80). This further supports the suggestion that quinones as well as quinonoid inhibitors interact directly with the histidine ligands of the Rieske cluster. [Pg.131]

Histidine forms a diacyl derivative that is apparently unstable. Moodie has suggested the use of ethoxyformic anhydride to form the stable Na-trifluoroacetyl-Nim-carbethoxy n-butyl histidinate with no accompanying unstable by-products (44). [Pg.469]

Treating ovotransferrin and human serum transferrin with 170-400 molar excess of ethoxyformic anhydride resulted in complete ethoxy-formylation of histidines with complete loss in iron-binding activity (33). The binding of each iron (two iron-binding sites per protein molecule) protected two histidines from ethoxyformylation, and in both cases the proteins remained completely active. These results plus kinetic analyses of the inactivations indicated two essential histidines in each binding site. Ethoxyformic anhydride also may react with amino groups. [Pg.25]

Other reagents which have been used for the modification of histidyl residues in proteins include l-fluoro-2,4-dinitrobenzene, diazonium-IH-tetrazole (see Andres and Atassi 1973), iodine (Covelli and Wolff 1966 Wolff and Covelli 1969), N-bromosuccinimide, ethoxyformic anhydride (Melchior and Fahrney 1970), and bromoacetone (Beeley and Neurath 1968). These reagents appear to offer little advantage over alkylation with a-haloacids, or dye-sensitized photo-oxidation. Indeed, some are far less specific. [Pg.90]
