In this illustration, a (green) integral membrane protein is modified by attachment of a (purple) carbohydrate in the ER.
WebThere are 5 major steps of the protein synthesis process are: Activation of amino acids Transfer of amino acids to tRNA Initiation of the polypeptide chain Chain termination and Translocation of the protein molecule This is the basic thumb rule for prokaryotes, while eukaryotes have some extra steps due to their cell complexity. WebIf an integral membrane protein is being synthesized, the hydro- philic portion is followed by a hydrophobic segment that remains anchored in the lipid bilayer. For proteins that span the membrane, synthesis is completed with the production of a final hydrophilic segment that faces the cytosol.
