| pubmed-article:10873828 | pubmed:abstractText | Recent studies show that transporters integrate into the lipid bilayer using topogenic sequences present throughout the entire polypeptide chain. These topogenic sequences can act in unpredictable ways with new translocation/stop transfer activities. In addition, a new membrane-insertion pathway has been identified in bacteria with homologs in mitochondria and chloroplasts. | lld:pubmed |
