STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

epmCElongation Factor P Lys34 hydroxylase; Is involved in the final hydroxylation step of the post- translational modification of translation elongation factor P (EF-P) on 'Lys-34'. Acts after beta-lysylation of 'Lys-34' by EpmA and EpmB. EpmC adds an oxygen atom to the C5 position of 'Lys-34' and does not modify the added beta-lysine. (182 aa)    
Predicted Functional Partners:
yfcA
TauE/TSUP family inner membrane protein; Putative structural protein.

epmB
EF-P-Lys34 lysylation protein; With EpmA is involved in the beta-lysylation step of the post-translational modification of translation elongation factor P (EF- P) on 'Lys-34'. EpmB appears to act before EpmA. Displays lysine 2,3- aminomutase activity, producing (R)-beta-lysine from (S)-alpha-lysine (L-lysine). Cannot use (S)-ornithine or (R)-alpha-lysine as a substrate; Belongs to the radical SAM superfamily. KamA family.

epmA
Elongation Factor P Lys34 lysyltransferase; 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'. The substrate (R)-beta-lysine is 100-fold more efficient than either (S)-beta-lysine or L-alpha-lysine. Cannot ligate lysine to any tRNA.

efp
Polyproline-specific translation elongation factor EF-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. Beta-lysylation at Lys- 34 is required for alleviation. The Pro codons and their context do not affect activity; only consecutive Pro residues (not another amino acid) are affected by EF-P. Has stimulatory effects on peptide bond formation between ribosome-bound initiator tRNA(fMet) and puromycin, [...]

mepA
Murein DD-endopeptidase; Murein endopeptidase that cleaves the D-alanyl-meso-2,6- diamino-pimelyl amide bond that connects peptidoglycan strands. Likely plays a role in the removal of murein from the sacculus and could also play a role in the integration of nascent murein strands into the sacculus.
  
    0.806
aroC
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. It uses NADPH to reduce FMN.

prmB
N5-glutamine methyltransferase; Specifically methylates the 50S ribosomal protein L3 on 'Gln- 150'. Does not methylate the translation termination release factors RF1 and RF2; Belongs to the protein N5-glutamine methyltransferase family. PrmB subfamily.
