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.

Score
metE5-methyltetrahydropteroyltriglutamate-- homocysteine methyltransferase; COG0620 [E] Methionine synthase II (cobalamin-independent). (374 aa)    
Predicted Functional Partners:
metK
S-adenosylmethionine synthetase; Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.
  
 0.840
luxS
Autoinducer-2 production protein / Ribosylhomocysteinase; Involved in the synthesis of autoinducer 2 (AI-2) which is secreted by bacteria and is used to communicate both the cell density and the metabolic potential of the environment. The regulation of gene expression in response to changes in cell density is called quorum sensing. Catalyzes the transformation of S-ribosylhomocysteine (RHC) to homocysteine (HC) and 4,5-dihydroxy-2,3-pentadione (DPD). Belongs to the LuxS family.
 
  
 0.712
LSL_0130
ABC transporter substrate-binding protein; COG1464 [P] ABC-type metal ion transport system, periplasmic component/surface antigen; Belongs to the nlpA lipoprotein family.
  
  
 0.694
metN
ABC transporter, ATP-binding protein; Part of the ABC transporter complex MetNIQ involved in methionine import. Responsible for energy coupling to the transport system.
  
  
 0.650
LSL_0132
COG2011 [P] ABC-type metal ion transport system, permease component.
  
  
 0.595
metC
COG0626 [E] Cystathionine beta-lyases/cystathionine gamma-synthases.
  
  
 0.562
metA
Homoserine O-succinyltransferase; Transfers an acetyl group from acetyl-CoA to L-serine, forming acetyl-L-serine; Belongs to the MetA family.
 
  
 0.557
fhs
Formate--tetrahydrofolate ligase; COG2759 [F] Formyltetrahydrofolate synthetase; Belongs to the formate--tetrahydrofolate ligase family.
  
 
 0.538
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
  
  
 0.487
prfC
Bacterial Peptide Chain Release Factor 3; Increases the formation of ribosomal termination complexes and stimulates activities of RF-1 and RF-2. It binds guanine nucleotides and has strong preference for UGA stop codons. It may interact directly with the ribosome. The stimulation of RF-1 and RF-2 is significantly reduced by GTP and GDP, but not by GMP. Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. PrfC subfamily.
