Fixed charge chemical modifications on peptides and proteins can impact fragmentation behaviors in tandem mass spectrometry (MS/MS). In this study, we employed a thiol-specific cationic alkylation reagent, (4-iodobutyl)triphenylphosphonium (IBTP), to selectively modify cysteine thiol groups in mitochondrial proteome samples. Tandem

1. Aerobic respiration by cells of Paracoccus dentrificans drives the uptake of the lipophilic cation butyltriphenylphosphonium. Anaerobiosis or addition of an uncoupler of oxidative phosphorylation (carbonyl cyanide p-trifluoromethoxyphenylhydrazone) results in efflux of the cation. Changes in the concentration of butyltriphenylphosphonium
Polyvinyl chloride membrane electrodes sensitive to tetraphenyl phosphonium (TPP+), butyltriphenyl phosphonium ( bTPP +), and methyltriphenyl phosphonium ( mTPP +) ions have been compared for the determination of the electrical potential difference (delta psi) of the oral bacteria, Streptococcus mutans
Archives of biochemistry and biophysics, 245(2), 436-445 (1986-03-01)
Equilibration of the butyltriphenyl phosphonium (BTPP+) cation into cytochrome c oxidase reconstituted proteoliposomes was measured potentiometrically. The maximum membrane potential (delta psi) generated by oxidase activity was estimated to lie between -65 and -90 mV, vesicle interior negative, when internal

Solid-state nuclear magnetic resonance has long been used to probe atomic distances between nearby nuclear spins by virtue of the dipolar interaction. New technological advances have recently enabled simultaneous tuning of the radio-frequency resonance circuits to nuclei with close Larmor
