Isolation and characterization of rubrerythrin, a non-heme iron protein from Desulfovibrio vulgaris that contains rubredoxin centers and a hemerythrin-like binuclear iron cluster.


A new non-heme iron protein from the periplasmic fraction of Desulfovibrio vulgaris (Hildenbourough NCIB 8303) has been purified to homogeneity, and its amino acid composition, molecular weight, redox potential, iron content, and optical, EPR, and Mössbauer spectroscopic properties have been determined. This new protein is composed of two identical subunits… (More)
