title: Mössbauer studies of cytochrome c-551. Intrinsic heterogeneity related to g-strain.
abstract: The Mössbauer spectra of oxidized and reduced cytochrome c-551 from Pseudomonas aeruginosa are analyzed. Excess broadening is observed in the 4.2 K spectra of oxidized c-551 which is consistent with a Gaussian distribution of the crystal field parameters delta and R as inferred from the g-strain model of EPR line shapes.
