Functional reconstitution of the hepatic system N amino acid transport activity.
Ontology highlight
ABSTRACT: Hepatic System N is responsible for the active plasma-membrane transport of glutamine, histidine and asparagine. This report describes the solubilization and reconstitution of System N activity. Differential solubility resulted in an approximate enrichment of almost 600-fold compared with total cell homogenate. The results indicate that reconstitution can be utilized as a functional assay during purification of the hepatic System N carrier protein.
