CC   -!- FUNCTION: With EpmB is involved in the beta-lysylation step of the
CC       post-translational modification of translation elongation factor P (EF-
CC       P) on 'Lys-34'. Catalyzes the ATP-dependent activation of (R)-beta-
CC       lysine produced by EpmB, forming a lysyl-adenylate, from which the
CC       beta-lysyl moiety is then transferred to the epsilon-amino group of EF-
CC       P 'Lys-34'. {ECO:0000255|HAMAP-Rule:MF_00174}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_00174}.
CC   -!- SIMILARITY: Belongs to the class-II aminoacyl-tRNA synthetase family.
CC       EpmA subfamily. {ECO:0000255|HAMAP-Rule:MF_00174}.
