polyprotein
Noun
Meaning
polyprotein (plural polyproteins)
(biochemistry) Any protein (especially ones produced by viruses) that cleave to produce a number of polypeptides, some of which act as hormones
Examples
Blood clotting (such as thrombin ) and viral polyprotein processing (such as TEV protease ) requires this level of specificity in order to achieve precise cleavage events.
Cleavage of polyproteins Some proteins and most eukaryotic polypeptide hormones are synthesized as a large precursor polypeptide known as a polyprotein that requires proteolytic cleavage into individual smaller polypeptide chains.
