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

ypmPConserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function; PubMedId: 15060025. (83 aa)    
Predicted Functional Partners:
ilvA
Threonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA (By similarity).
  
  
 0.858
ilvE
Ketomethiobutyrate-branched-chain/aromatic amino acid aminotransferase; Transaminates branched-chain amino acids and ketoglutarate. Involved in the final step of the methionine regeneration pathway, where ketomethiobutyrate (KMTB) is converted to methionine via a transamination. The amino donor preference is isoleucine, leucine, valine, phenylalanine, and tyrosine; Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
   
  
 0.575
scuA
Assembly factor BSco of the Cu(A) site of cytochrome c oxidase; Necessary for insertion of copper into the active site of cytochrome c oxidase. May play a role in copper homeostasis or redox signaling; Belongs to the SCO1/2 family.
  
    0.553
ilvD
Dihydroxy-acid dehydratase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the IlvD/Edd family.
   
  
 0.499
ilvC
Acetohydroxy-acid isomeroreductase; Involved in the biosynthesis of branched-chain amino acids (BCAA). Catalyzes an alkyl-migration followed by a ketol-acid reduction of (S)-2-acetolactate (S2AL) to yield (R)-2,3-dihydroxy-isovalerate. In the isomerase reaction, S2AL is rearranged via a Mg-dependent methyl migration to produce 3-hydroxy-3-methyl-2-ketobutyrate (HMKB). In the reductase reaction, this 2-ketoacid undergoes a metal-dependent reduction by NADPH to yield (R)-2,3-dihydroxy-isovalerate.

ypmR
Putative exported lipase/acylhydrolase (lipoprotein); Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
  
    0.403
yplQ
Putative membrane hydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
