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

Rv3404cConserved hypothetical protein; Sugar N-formyltransferase that catalyzes the conversion of dTDP-4-amino-4,6-dideoxyglucose into dTDP-4-formamido-4,6- dideoxyglucose using N(10)-formyltetrahydrofolate as the carbon source. Plays a role in virulence. Has no activity on dTDP-3-amino-3,6-dideoxyglucose, dTDP-3-amino-3,6- dideoxygalactose, UDP-4-amino-4-deoxyarabinose, and GDP-4-amino-4,6- dideoxymannose. (234 aa)    
Predicted Functional Partners:
fmu
Probable Fmu protein (sun protein); May act as RNA methyltransferase.

Rv3403c
Hypothetical protein; Rv3403c, (MTCY78.25), len: 533 aa. Hypothetical unknown protein, but some weak similarity to Q9KJP2 hypothetical 54.9 KDA protein from Myxococcus xanthus (504 aa), FASTA scores: opt: 157, E(): 0.011, (24.1% identity in 548 aa overlap).
 
    0.798
pstP
Phosphoserine/threonine phosphatase PstP; The only predicted protein phosphatase in M.tuberculosis, it dephosphorylates at least 5 protein kinases (PknA, PknB, PknD, PknE and PknF) and the penicillin-binding protein PBPA.
  
   0.748
nusB
N utilization substance protein NusB (NusB protein); Involved in transcription antitermination. Required for transcription of ribosomal RNA (rRNA) genes. Binds specifically to the boxA antiterminator sequence of the ribosomal RNA (rrn) operons.
  
  
 0.710
Rv3402c
Rv3402c, (MTCY78.26), len: 412 aa. Conserved hypothetical protein, probably involved in cell process,similar to various proteins generally involved in extracellular compounds (lipopolysaccharide O-antigen) biosynthesis e.g. O68392|RFBE perosamine synthetase from Brucella melitensis (367 aa), FASTA scores: opt: 420, E(): 1.2e-19, (26.15% identity in 375 aa overlap); Q9L6C1 3,4-dehydratase-like protein from Streptomyces antibioticus (393 aa), FASTA scores: opt: 419, E(): 1.5e-19, (30.65% identity in 385 aa overlap); Q9RR26|OLENI dehydratase from Streptomyces antibioticus (393 aa), FASTA [...]

priA
Putative primosomal protein N' PriA (replication factor Y); Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA; Belongs to the helicase family. PriA subfamily.
  
    0.655
Rv3405c
Possible transcriptional regulatory protein; Negatively regulates the expression of sulfate ester dioxygenase Rv3406 and its own expression. Binds specifically to the inverted repeat sequence of the intergenic region between Rv3405c and Rv3406.
  
    0.642
thyA
Probable thymidylate synthase ThyA (ts) (TSASE); Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by- product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis. Belongs to the thymidylate synthase family. Bacterial-type ThyA subfamily.
  
  
 0.609
def
Probable polypeptide deformylase Def (PDF) (formylmethionine deformylase); Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions (By similarity); Belongs to the polypeptide deformylase family.
  
 
 0.582
gatC
Probable glutamyl-tRNA(GLN) amidotransferase (subunit C) GatC (Glu-ADT subunit C); Allows the formation of correctly charged Asn-tRNA(Asn) or Gln-tRNA(Gln) through the transamidation of misacylated Asp-tRNA(Asn) or Glu-tRNA(Gln) in organisms which lack either or both of asparaginyl- tRNA or glutaminyl-tRNA synthetases. The reaction takes place in the presence of glutamine and ATP through an activated phospho-Asp- tRNA(Asn) or phospho-Glu-tRNA(Gln) (By similarity); Belongs to the GatC family.
