YfcL protein.

Elongation factor P; 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; Belongs to the elongation factor P family.

L-lysine 2,3-aminomutase.

Chorismate synthase; Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.

N-acetylglutamate synthase.

Elongation factor P--(R)-beta-lysine ligase; 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; Belongs to the class-II aminoacyl-tRNA synthetase family. EpmA subfamily.

tRNA (guanosine(18)-2'-O)-methyltransferase; Catalyzes the 2'-O methylation of guanosine at position 18 in tRNA; Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase TrmH family.

50S ribosomal protein L3 glutamine methyltransferase; Specifically methylates the 50S ribosomal protein L3 on a specific glutamine residue; Belongs to the protein N5-glutamine methyltransferase family. PrmB subfamily.
