Comments
Requires a univalent cation. The enzyme participates in the N-end rule protein degradation pathway in certain bacteria, by attaching the primary destabilizing residue L-leucine to the N-termini of proteins that have an N-terminal L-arginine or L-lysine residue. Once modified, the proteins are recognized by EC 3.4.21.92, the ClpAP/ClpS endopeptidase system. The enzyme also transfers L-phenylalanine in vitro, but this has not been observed in vivo [5]. cf. EC 2.3.2.29, aspartate/glutamate leucyltransferase, and EC 2.3.2.8, arginyltransferase.
