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

chaARv1607, (MTV046.05), len: 360 aa. Probable chaA,ionic transporter integral membrane protein, putative calcium/proton antiporter, similar to many e.g. P31801|CHAA_ECOLI calcium/proton antiporter from Escherichia coli (366 aa), FASTA scores: opt: 736, E(): 0,(35.9% identity in 351 aa overlap). Equivalent to Mycobacterium leprae AL049913|MLCB1610_21 (77.7% identity in 364 aa overlap). Seems to belong to the CaCA family. (360 aa)    
Predicted Functional Partners:
mntH
Divalent cation-transport integral membrane protein MntH (BRAMP) (MRAMP); H(+)-stimulated, divalent metal cation uptake system. Transports zinc and iron. Can also interact with manganese and copper.
   
  
 0.608
hisA
Probable phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase HisA; Involved in both the histidine and tryptophan biosynthetic pathways; Belongs to the HisA/HisF family.
  
  
 0.505
vapC21
Possible toxin VapC21; Toxic component of a type II toxin-antitoxin (TA) system. An RNase (By similarity). Upon expression in M.smegmatis inhibits colony formation. Its toxic effect is neutralized by coexpression with cognate antitoxin VapB21; Belongs to the PINc/VapC protein family.
  
    0.502
hisF
Probable cyclase HisF; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit (By similarity).
  
    0.489
yjcE
Rv2287, (MTCY339.23c), len: 542 aa. Probable yjcE,conserved integral membrane transport protein, similar to eukaryote NA+/H+ exchangers e.g. YJCE_ECOLI|P32703|B4065 Putative Na(+)/H(+) exchanger from Escherichia coli (549 aa), FASTA scores: opt: 436, E(): 5.6e-21, (29.4% identity in 555 aa overlap); etc. Seems to belong to CPA1 family (NA(+)/H(+) exchanger family).
 
 
 0.489
impA
Probable inositol-monophosphatase ImpA (imp); Catalyzes the dephosphorylation of inositol 1-phosphate (I-1- P) to yield free myo-inositol, a key metabolite in mycobacteria.
  
    0.485
hisI
Probable phosphoribosyl-AMP 1,6 cyclohydrolase HisI; Catalyzes the hydrolysis of the adenine ring of phosphoribosyl-AMP.
  
    0.484
ccsA
Rv0529, (MTCY25D10.08), len: 324 aa. Possible ccsA,cytochrome C-type biogenesis protein, integral membrane protein, equivalent to NP_302558.1|NC_002677|B2168_C3_281 possible cytochrome C biogenesis protein from Mycobacterium leprae (327 aa), FASTA scores: opt: 1779, E(): 0, (82.9% identity in 327 aa overlap). Also highly similar to others e.g. CAC08382.1|AL392176 putative cytochrome biogenesis related protein from Streptomyces coelicolor (380 aa); CCSA_CHLRE|P48269 probable cytochrome c biogenesis protein from Chlamydomonas reinhardtii (353 aa), FASTA scores: opt: 449, E(): 1.3e-23, (3 [...]

hisD
Probable histidinol dehydrogenase HisD (HDH); Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
  
    0.474
hisH
Probable amidotransferase HisH; IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisH subunit catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the synthesis of IGP and AICAR. The resulting ammonia molecule is channeled to the active site of HisF (By similarity).
