Abstract excerpt
To gain insights in the relationships of specific amino acid residues with the active site of the mitochondrial ornithine/citrulline carrier, we studied the effect of specific protein modifying reagents on the transport catalysed by the carrier reconstituted into liposomes. It was found that, besides the sulfhydryl reagents NEM, MTSEA, p-hydroxymercuribenzoate, diamide also the lysine reagents PLP, DIDS, SITS,...
