First, a ubiquitin molecule is bonded by its C-terminus to a specific lysine residue on the target protein.
The beta and the gamma isoforms are generated by multiple splicing of intron 9, which leads to a different C-terminus.
Several analogous systems are found that likewise feature a signature motif on the extracytoplasmic face, a C-terminal transmembrane domain, and cluster of basic residues on the cytosolic face at the protein's extreme C-terminus.
Specific amino acid sequences (PTS or peroxisomal targeting signal ) at the C-terminus (PTS1) or N-terminus (PTS2) of peroxisomal matrix proteins signals them to be imported into the organelle.
It is attached to the polypeptide C-terminus through an amide linkage that then connects to ethanolamine, thence to sundry sugars and finally to the phosphatidylinositol lipid moiety.
It is oriented with the N-terminus outside the cell and the C-terminus in the cytosol.
