Enzyme Information
| 2.3.2.6 |
Lysine/arginine leucyltransferase.
based on mapping to UniProt P0A8P1
(1) L-leucyl-tRNA(Leu) + N-terminal L-lysyl-[protein] = tRNA(Leu) + N-terminal L-leucyl-L-lysyl-[protein]. (2) L-leucyl-tRNA(Leu) + N-terminal L-arginyl-[protein] = tRNA(Leu) + N-terminal L-leucyl-L-arginyl-[protein].
-!- 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 enzyme also transfers L-phenylalanine in vitro, but this has not been observed in vivo. -!- Cf. EC 2.3.2.8 and EC 2.3.2.29.
