Fig. 3From: 1,2-Dichlorobenzene affects the formation of the phosphoenzyme stage during the catalytic cycle of the Ca2+-ATPase from sarcoplasmic reticulumBinding of Ca2+ to SERCA. To test if 1,2-DCB was affecting the binding of Ca2+ to the enzyme we performed a binding assay as described in Methods . The complex Ca2+/SERCA (E1Ca2) (o) or enzyme prior binding to Ca2+ (E2) (●) were exposed to different concentrations of 1,2-DCBBack to article page
