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). Catalyzes the ATP-dependent activation of (R)-beta-lysine produced
CC       by EpmB, forming a lysyl-adenylate, from which the beta-lysyl moiety is
CC       then transferred to the epsilon-amino group of a conserved specific
CC       lysine residue in EF-P. {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}.
