The histidine permease
WebThe histidine-specific permease gene (HIP1) of Saccharomyces cerevisiae has been mapped, cloned, and sequenced. The HIP1 gene maps to the right arm of chromosome VII, approx. 11 cM distal to the ADE3 gene. The gene was isolated as an 8.6-kb BamHI-Sau3A fragment by complementation of the histidine-specific permease deficiency in recipient … Webacid permease (Aap) and the branched-chain amino acid permease (Bra) of Rhizobium leguminosarum and the histidine permease (His) of Salmonella typhimurium, are bidirectional, being responsible for efflux in addition to the uptake of solutes. The net solute movement measured for an ABC transporter depends on the rates of uptake and efflux ...
