Materials and MethodsBeef heart cardiolipin (sodium salt) and cytochrome c (grade VI) were obtained from Sigma Chemical Co.(St. Louis, MO). Dimyristoylphosphatidylcholine puriss was from Fluka (Buchs, Switzerland). Spin-labeled maleimide (4-maleimido-2, 2, 6, 6-tetramethyl-l-piperidineoxyl) was from Syva (Palo Alto, CA). Cytochrome oxidase was prepared from beef heart by using the method of Yu et al.(1975) with modifications given in Cable and Powell (1980). Lipid substitution by di-myristoylphosphatidylcholine was carried out according to the method described by Knowles et al.(1979), butwith omission of sucrose and KC1 from the buffers. Further details are given in Powellet al.(1987). Lipid substitution by cardiolipin was performed by a similar method, except that two exchanges with a 10-fold excess of cardiolipin were employed. Cardiolipin samples were handled under N2 to inhibit lipid peroxidation. The final cardiolipin-substituted preparations were centrifuged through either 1, 2, or 4 M NaCl to resolve the protein/lipid complexes from unincorporated lipid. Sucrose density gradient centrifugation then demonstrated that the complexes sedimented as a single band and contained no free lipid. Salt concentration was varied by resuspending and washing the1 Abbreviations: NMR, nuclear magnetic resonance; ESR, electron spin resonance; STESR, saturation-transfer ESR; V/, second harmonic ESR absorption signal detected 90 out-of-phase with respect to the field modulation; EM, electron microscopy; TLC, thin-layer chromatography; L „, fluid lamellar lipid phase; Hn, inverted hexagonal lipid phase.
