[[http://www.uniprot.org/uniprot/C3SGA2_ECOLX C3SGA2_ECOLX]] 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' (By similarity).[HAMAP-Rule:MF_00174] [[http://www.uniprot.org/uniprot/C3SGD7_ECOLX C3SGD7_ECOLX]] Involved in peptide bond synthesis. Alleviates ribosome stalling that occurs when 3 or more consecutive Pro residues or the sequence PPG is present in a protein, possibly by augmenting the peptidyl transferase activity of the ribosome. Modification of Lys-34 is required for alleviation (By similarity).[HAMAP-Rule:MF_00141]

The substrate (R)-beta-lysine is 100-fold more efficient than either (S)-beta-lysine or L-alpha-lysine.
