| umls-concept:C0001479 | skos:definition | MSH: An enzyme that catalyzes the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane ATPase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients.,CSP: family of ouabain-sensitive, ATP-driven, transmembrane molecular pumps which maintain opposing concentration gradients of sodium and potassium across cell membranes term not valid for FY 92. | lld:umls |
