The ferric and ferrous forms of bovine erythrocyte green hemeprotein react with hydroperoxides to form higher oxidation state intermediates with absorbance maxima in the Soret region at 426 and 422 nm, respectively. In the absence of an appropriate r

Bovine erythrocyte green hemoprotein was shown to undergo rapid and complete bleaching during aerobic reduction by dithionite. In order to explain this phenomenon, we have studied the reactions of the ferrihemoprotein with dithionite and H202 and the

A procedure has been developed for the methylation of hemins using trimethyloxonium tetrafluoroborate. The method is rapid and selective for carboxyl groups, and it can be used to methylate polar and nonpolar hemins under neutral and basic conditions

Field desorption mass spectrometry was shown to be a valid technique for determining the molecular weights of hemins and hemin esters, as well as of porphyrins. The observed base peaks of ligand-free protoheme IX, protoheme IX dimethyl ester, and pro
