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

Score
dcdProbable deoxycytidine triphosphate deaminase Dcd (dCTP deaminase); Bifunctional enzyme that catalyzes both the deamination of dCTP to dUTP and the hydrolysis of dUTP to dUMP without releasing the toxic dUTP intermediate. It also acts as a dUTP diphosphatase. Affinity for dCTP and dUTP are very similar. (190 aa)    
Predicted Functional Partners:
dut
Deoxyuridine 5'-triphosphate nucleotidohydrolase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA; Belongs to the dUTPase family.
    
 0.930
pyrG
Probable CTP synthase PyrG; Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen. Is essential for M.tuberculosis growth in vitro and ex vivo. Regulates intracellular CTP levels through interactions with the four ribonucleotide triphosphates (By similarity).
  
 
 0.927
ndkA
Probable nucleoside diphosphate kinase NdkA (NDK) (NDP kinase) (nucleoside-2-P kinase); Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
  
 
 0.926
cobI
Cobalamin biosynthesis protein CobIJ; Methylates precorrin-2 at the C-20 position to produce precorrin-3A.

Rv0320
Rv0320, (MTCY63.25), len: 220 aa. Possible conserved exported protein, similar to some hypothetical proteins and to the middle part of a peptidase: NP_066789.1|10657900|AAG21739.1|AF116907 putative peptidase from Rhodococcus equi (546 aa). Also similar to Rv1728c|MTCY04C12.13c from Mycobacterium tuberculosis (256 aa), FASTA scores: opt: 497, E(): 1.2e-26, (41.8% identity in 225 aa overlap). Predicted to be an outer membrane protein (See Song et al., 2008).

hemL
Rv0524, (MTCY25D10.03), len: 462 aa. Probable hemL,glutamate-1-semialdehyde 2,1-aminomutase, equivalent to P46716|GSA_MYCLE glutamate-1-semialdehyde 2,1-aminomutase from Mycobacterium leprae (446 aa), FASTA scores: opt: 1532, E(): 0, (82.6% identity in 460 aa overlap). Also highly similar to others e.g. Q9F2S0|GSA_STRCO from Streptomyces coelicolor (438 aa); Q06774|GSA_PROFR from Propionibacterium freudenreichii (441 aa); etc. Contains PS00600 Aminotransferases class-III pyridoxal-phosphate attachment site. Belongs to class-III of pyridoxal-phosphate-dependent aminotransferases. Cofact [...]

Probable cspB,cold shock-like protein B, equivalent to Z99494|MLCB57_7|MLCB57.11 probable cold shock protein from Mycobacterium leprae (136 aa), FASTA scores: opt: 787, E(): 0, (86.0% identity in 136 aa overlap). Also highly similar (but often longer than) to others e.g. CAB93399.1|AL357524 cold shock protein B from Streptomyces coelicolor (127 aa); Q45099|CSPD_BACCE cold shock-like protein CSPD from Bacillus cereus (66 aa); Y101 81|LLCSPB_1 cold shock protein from Lactococcus lactis (66 aa), FASTA scores: opt: 220, E(): 2.5e-07, (48.3% identity in 60 [...]

fmt
Probable methionyl-tRNA formyltransferase Fmt; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
      
 0.657
rmlD
dTDP-4-dehydrorhamnose reductase; Involved in the biosynthesis of the dTDP-L-rhamnose which is a component of the critical linker, D-N-acetylglucosamine-L-rhamnose disaccharide, which connects the galactan region of arabinogalactan to peptidoglycan via a phosphodiester linkage. Catalyzes the reduction of dTDP-6-deoxy-L-lyxo-4-hexulose to yield dTDP-L- rhamnose (By similarity).
