CC   -!- FUNCTION: Functions in the N-end rule pathway of protein degradation
CC       where it conjugates Leu, Phe and, less efficiently, Met from aminoacyl-
CC       tRNAs to the N-termini of proteins containing an N-terminal arginine or
CC       lysine. {ECO:0000255|HAMAP-Rule:MF_00688}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-leucyl-tRNA(Leu) + N-terminal L-lysyl-[protein] = H(+) + N-
CC         terminal L-leucyl-L-lysyl-[protein] + tRNA(Leu);
