The C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, carboxy tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH). When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus. The ...
The 5′-end (pronounced "five prime end") designates the end of the DNA or RNA strand that has the fifth carbon in the sugar-ring of the deoxyribose or ribose at its terminus. A phosphate group attached to the 5′-end permits ligation of two nucleotides , i.e., the covalent binding of a 5′-phosphate to the 3′-hydroxyl group of another ...

The C-terminus can also be blocked (thus, neutralizing its negative charge) by amination. glycosyl phosphatidylinositol (GPI) attachment Glycosyl phosphatidylinositol (GPI) is a large, hydrophobic phospholipid prosthetic group that anchors proteins to cellular membranes .
Carboxypeptidase A usually refers to the pancreatic exopeptidase that hydrolyzes peptide bonds of C-terminal residues with aromatic or aliphatic side-chains. Most scientists in the field now refer to this enzyme as CPA1 , and to a related pancreatic carboxypeptidase as CPA2 .
Group I proteins have the N terminus on the far side and C terminus on the cytosolic side. Group II proteins have the C terminus on the far side and N terminus in the cytosol. However final topology not the only criterion for defining transmembrane protein groups, rather location of topogenic determinants and mechanism of assembly is considered ...

The c-terminal tail domain contains a nuclear localization signal (NLS), an Ig-fold-like domain, and in most cases a carboxy-terminal CaaX box that is isoprenylated and carboxymethylated (lamin C does not have a CAAX box). Lamin A is further processed to remove the last 15 amino acids and its farnesylated cysteine.
