3a5z | pdb_00003a5z
Crystal structure of Escherichia coli GenX in complex with elongation factor P
Function
[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] [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]
