Abstract
In summary, we have begun to characterize three different ion pathways in the sarcoplasmic reticulum. Ca2+-ionophoric activity has been traced to a 13,000-dalton CNBr fragment localized at the amino terminus of the ATPase molecule... The pathway involved in Ca2+ release can be distinguished from the pathway involved in Ca2+ uptake by its insensitivity to quercetin. An anion pathway is sensitive to DIDS and appears to be localized in the ATPase moleculeKeywords
