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

MJ_0969Conserved hypothetical protein; Phosphorylates (R)-pantoate to form (R)-4-phosphopantoate in the CoA biosynthesis pathway. (270 aa)    
Predicted Functional Partners:
MJ_0209
Conserved hypothetical protein; Catalyzes the condensation of (R)-4-phosphopantoate and beta- alanine to 4'-phosphopantothenate in the CoA biosynthesis pathway. Belongs to the archaeal phosphopantothenate synthetase family.
 
  
 0.998
htpX
Heat shock protein HtpX, possibly protease (htpX); Similar to GB:M58470 SP:P23894 PID:146412 GB:U00096 PID:1736470 percent identity: 34.96; identified by sequence similarity; putative; Belongs to the peptidase M48B family.
  
    0.971
coaBC
Pantothenate metabolism flavoprotein (dfp); Catalyzes two sequential steps in the biosynthesis of coenzyme A. In the first step cysteine is conjugated to 4'- phosphopantothenate to form 4-phosphopantothenoylcysteine. In the second step the latter compound is decarboxylated to form 4'- phosphopantotheine; In the C-terminal section; belongs to the PPC synthetase family.
 
   
 0.946
alaS
alanyl-tRNA synthetase (alaS); Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala) (By similarity). Also functions in trans to edit the amino acid moiety from incorrectly charged Ser-tRNA(Ala), and maybe also from Gly-tRNA(Ala).
  
    0.841
metE
5-methyltetrahydropteroyltriglutamate- homocysteine methyltransferase (metE); Catalyzes the transfer of a methyl group to L-homocysteine resulting in methionine formation. Can use methylcobalamin and methylcobinamide as methyl donors, but methylcobalamin is not considered to be the physiological substrate (By similarity).
  
    0.825
ilvC
Ketol-acid reductoisomerase (ilvC); 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.
      
 0.771
MJ_0719
RNase L inhibitor; Similar to PIR:S63672 percent identity: 48.74; identified by sequence similarity; putative; Belongs to the ABC transporter superfamily.
   
    0.687
MJ_0039
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 44.44; identified by sequence similarity; putative.

tfe
Putative transcription initiation factor (TFIIE, subunit alpha); Transcription factor that plays a role in the activation of archaeal genes transcribed by RNA polymerase. Facilitates transcription initiation by enhancing TATA-box recognition by TATA-box-binding protein (Tbp), and transcription factor B (Tfb) and RNA polymerase recruitment. Not absolutely required for transcription in vitro, but particularly important in cases where Tbp or Tfb function is not optimal. It dynamically alters the nucleic acid-binding properties of RNA polymerases by stabilizing the initiation complex and d [...]

nusA
Putative transcription termination-antitermination factor (NusA); Participates in transcription termination. Belongs to the NusA family.
