Transferases are enzymes which transfer a group from a donor molecule to an acceptor molecule. Generally, transferases are enzymes involved in tRNA metabolism, which encompasses tRNA breakdown, modification and synthesis. Essentially, this function is important in cellular processes such as protein synthesis. Isopentenyltransferase transfers an isopentenyl group to the acceptor molecule and as the name tRNA isopentenyltransferase (tRNA-IPT) suggests, it transfers the isopentenyl group of dimethylallyl pyrophosphate to tRNA molecules.
