| case <OC:Escherichia> or <OC:Shigella> or <OC:Salmonella> | |
| FUNCTION | 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'. |

| FUNCTION | With EpmB is involved in the beta-lysylation step of the post-translational modification of translation elongation factor P (EF- P). 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 a conserved specific lysine residue in EF-P. |
