On reconstitution of the Ca(2+)-ATPase of skeletal muscle sarcoplasmic reticulum into bilayers of dimyristoleoylphosphatidylcholine [di(C14:1)PC] or dinervonylphosphatidylcholine [di(C24:1)PC] the stoichiometry of Ca2+ binding changes from the usual two Ca2+ ions bound per ATPase molecule to one Ca2+ ion bound per

Biochemistry, 31(26), 6023-6031 (1992-07-07)
The (Ca(2+)-Mg2+)-ATPase of sarcoplasmic reticulum was labeled with 4-(bromomethyl)-6,7-dimethoxycoumarin. It was shown that a single cysteine residue (Cys-344) was labeled on the ATPase, with a 25% reduction in steady-state ATPase activity and no reduction in the steady-state rate of hydrolysis

Proteins, 78(14), 2973-2983 (2010-08-26)
Kinetic measurement of protein folding is limited by the method used to trigger folding. Traditional methods, such as stopped flow, have a long mixing dead time and cannot be used to monitor fast folding processes. Here, we report a compound

Analytica chimica acta, 690(2), 209-214 (2011-03-26)
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been broadly applied to analyze high-molecular-weight compound (such as polymer or proteomic research) but seldom used for low-molecular-weight compound analysis. The objective of this study is the development of a
