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

Rv0849Rv0849, (MTV043.42), len: 419 aa. Probable conserved integral membrane transport protein, possibly member of major facilitator superfamily (MFS) involved in transport of drug, showing similarity with others e.g. T35055 probable transport system permease protein from Streptomyces coelicolor (436 aa); NP_295031.1|NC_001263 major facilitator family protein from Deinococcus radiodurans (458 aa); NP_455659.1|NC_003198 putative membrane transporter from Salmonella enterica subsp. enterica serovar Typhi (402 aa); etc. (419 aa)    
Predicted Functional Partners:
cysK2
S-sulfocysteine synthase; Catalyzes the synthesis of S-sulfocysteine, utilizing O- phosphoserine (OPS) and thiosulfate as substrates. To a lesser extent, can also use sulfide as donor substrate, producing L-cysteine. CysK2 thus provides a third metabolic route to cysteine, either directly using sulfide as donor or indirectly via S-sulfocysteine. S- sulfocysteine might also act as a signaling molecule triggering additional responses in redox defense in the pathogen upon exposure to reactive oxygen species during intracellular survival or dormancy. Cannot utilize thiocarboxylated CysO as [...]

lpqS
Probable lipoprotein LpqS; May play an essential role in M.tuberculosis replication and survival inside the host cell.
  
  
 0.969
mmcO
Probable oxidase; Required for copper resistance. In vitro, oxidizes organic substrates and Fe(2+). May act in vivo by oxidation of toxic periplasmic Cu(+); Belongs to the multicopper oxidase family.
