How a protocell forms
WebSome hydrophobic amino acids chelate FeS nanocrystals, producing three positive feedbacks: (i) an increase in catalytic surface area; (ii) partitioning of FeS nanocrystals to the membrane; and (iii) a proton-motive active site for carbon fixing … WebModel protocells in form of giant unilamellar compartments are initially adhered to a solid substrate via Ca2+ anchors, but the adhesion is subsequently reversed upon depletion of Ca2+. Small membrane regions released from the surface transform into small unilamellar subcompartments inside the model protocell.
