Function
EPMA_SALTY With EpmB is involved in the beta-lysylation step of the post-translational modification of translation elongation factor P (EF-P) on 'Lys-34'. Catalyzes the ATP-dependent activation of (R)-beta-lysine produced by EpmB, forming a lysyl-adenylate, from which the beta-lysyl moiety is then transferred to the epsilon-amino group of EF-P 'Lys-34' (Probable). Can also use L-alpha-lysine as a substrate, but probably with lower efficiency. Cannot aminoacylate tRNA(Lys) with lysine.[HAMAP-Rule:MF_00174][1]
