title: ENDOR from nitrogens and protons in low spin ferric heme and hemoprotein.
abstract: Electron nuclear double resonance (ENDOR) signals have been obtained from iron-linked nitrogens in frozen solutions of cytochrome c, metmyoglobin cyanide, and a low spin protohemin mercaptide complex. Hyperfine couplings from heme protons have also been obtained from metmyoglobin cyanide and from a low spin protohemin cyanide complex. Several of these proton resonances are assigned to specific heme protons.
