Edible oils consist primarily of triacylglycerols (TAGs). Matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectra of the oils are typically dominated by sodium adducts of… (More)
The reaction between cytochrome c (CC) and cytochrome c peroxidase (CcP) is a very attractive system for investigating the fundamental mechanism of biological electron transfer. The resting ferric… (More)
The P(M)-->F transition of the catalytic cycle of cytochrome c oxidase from bovine heart was investigated using single-electron photoreduction and monitoring the subsequent events using spectroscopic… (More)
Long-range movement of the Rieske iron-sulfur protein (ISP) between the cytochrome (cyt) b and cyt c1 redox centers plays a key role in electron transfer within the cyt bc1 complex. A series of 21… (More)
The reactions of Rhodopseudomonas viridis cytochrome c2 and horse cytochrome c with Rps. viridis photosynthetic reaction centers were studied by using both single- and double-flash excitation.… (More)
The synthesis of (4-bromomethyl-4'-methylbipyridine) [bis(bipyridine)]ruthenium(II) hexafluorophosphate is described. This new reagent was found to selectively label the single sulfhydryl group at… (More)
The first step in the catalytic cycle of cytochrome oxidase, the one-electron reduction of the fully oxidized enzyme, was investigated using a new photoactive binuclear ruthenium complex,… (More)
The reaction between cytochrome c (Cc) and Rhodobacter sphaeroides cytochrome c oxidase (CcO) was studied using a cytochrome c derivative labeled with ruthenium trisbipyridine at lysine 55… (More)
Electron transfer (ET) between Paracoccus denitrificans cytochrome (cyt) c(1) and cytochrome c(552) was studied using the soluble redox fragments cyt c(1CF) and cyt c(552F). A new ruthenium cyt… (More)
