prenylöinti
Prenylöinti is a biochemical process involving the addition of a prenyl group to a molecule. A prenyl group is a five-carbon isoprenoid unit, specifically an alkyl group derived from isoprene. This addition is typically catalyzed by enzymes called prenyltransferases. These enzymes play crucial roles in the modification of various biomolecules, including proteins, lipids, and small molecules.
In protein prenylation, prenyl groups are attached to cysteine residues at or near the C-terminus of proteins.
Prenylöinti also occurs in the biosynthesis of natural products, such as flavonoids and alkaloids. In these
