high-field electron paramagnetic resonance spectroscopy of frozen solutions and single crystals of the one-electron reduced protein-substrate complex of mutant D102N. Spectra reveal a biliverdin radical with a very narrow g tensor. This g tensor is consistent with a biliverdin radical where the carbonyl oxygen atoms on both the A and the D pyrrole rings are protonated | Nostoc sp. PCC 7120 = FACHB-418 |
high-field electron paramagnetic resonance spectroscopy of frozen solutions and single crystals of the one-electron reduced protein-substrate complex of mutant D105N. Spectra reveal a biliverdin radical with a very narrow g tensor with principal values 2.00359(5), 2.00341(5), and 2.00218(5). This g tensor is consistent with a biliverdin radical where the carbonyl oxygen atoms on both the A and the D pyrrole rings are protonated | Synechocystis sp. |
