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

Rv1433Possible conserved exported protein; Probable L,D-transpeptidase that may perform as-yet-unknown cross-linking reactions in M.tuberculosis. Is not able to generate 3->3 cross-links in peptidoglycan, using tetrapeptide stems as acyl donor substrates. May function in the anchoring of proteins to peptidoglycan. (271 aa)    
Predicted Functional Partners:
Rv3015c
Rv3015c, (MTV012.29c), len: 337 aa. Conserved hypothetical protein, equivalent to Q9CBR6|ML1706 hypothetical protein from Mycobacterium leprae (337 aa),FASTA scores: opt: 1703, E(): 3.1e-92, (78.05% identity in 337 aa overlap); and (but longer 47 aa) O33101|MLCB637.09 hypothetical 30.0 KDA protein from Mycobacterium leprae (290 aa), FASTA scores: opt: 1564, E(): 2.4e-78, (78.6% identity in 290 aa overlap). Also similar to Q9Z586|SC8D9.05 hypothetical 35.0 KDA protein from Streptomyces coelicolor (331 aa), FASTA scores: opt: 774,E(): 4.7e-38, (43.4% identity in 334 aa overlap); and show [...]

ftsQ
Possible cell division protein FtsQ; Essential cell division protein.
  
  
 0.628
Rv1863c
Rv1863c, (MTCY359.10), len: 256 aa. Probable conserved integral membrane protein, similar to Rv0804|Z95618|MTCY7H7A.05 Hypothetical protein from Mycobacterium tuberculosis (209 aa), FASTA scores: opt: 199, E(): 1e-06, (33.2% identity in 220 aa overlap); and Rv0658c.
  
  
 0.595
ripA
Peptidoglycan hydrolase; Peptidoglycan endopeptidase that cleaves the bond between D- glutamate and meso-diaminopimelate. Binds and degrades high-molecular weight peptidoglycan from a number of Actinobacteria; activity is increased in the presence of RpfB and inhibited by PBP1A (ponA1). Required for normal separation of daughter cells after cell division and for cell wall integrity. Required for host cell invasion and intracellular survival in host macrophages. Belongs to the peptidase C40 family.
  
  
 0.549
Rv1431
Conserved membrane protein; Rv1431, (MTCY493.23c), len: 589 aa. Conserved membrane protein, shows strong similarity to another M. tuberculosis hypothetical protein Rv1132|MTCY22G8.21 (48.2% identity in 585 aa overlap).
  
    0.497
Rv1432
Rv1432, (MTCY493.22c), len: 473 aa. Probable dehydrogenase, shows strong similarity to P49_STRLI|P06108 p49 protein from Streptomyces lividans (469 aa), FASTA scores: opt: 1362, E(): 0, (44.9% identity in 474 aa overlap); and weak similarity to other dehydrogenases.

Rv3627c
Conserved protein; Carboxypeptidase that cleaves terminal D-alanine from peptidoglycan in the mycobacterial cell wall. May cleave L-Lys-D-Ala and/or D-Ala-D-Ala peptide bonds. Exerts important effects on mycobacterial cell morphology and cell division. Belongs to the peptidase S13 family.
 
  
 0.464
lprQ
Probable conserved lipoprotein LprQ; Generates 3->3 cross-links in peptidoglycan, catalyzing the cleavage of the mDap(3)-D-Ala(4) bond of a tetrapeptide donor stem and the formation of a bond between the carbonyl of mDap(3) of the donor stem and the side chain of mDap(3) of the acceptor stem. Is specific for donor substrates containing a stem tetrapeptide since it cannot use pentapeptide stems.
  
  
0.455
cwlM
Probable peptidoglycan hydrolase; Cell-wall hydrolase that hydrolyzes the amide bond between N- acetylmuramic acid and L-alanine in cell-wall glycopeptides. Is able to lyse whole mycobacteria, release peptidoglycan from the cell wall of M.luteus and M.smegmatis, and cleave N-acetylmuramoyl-L-alanyl-D- isoglutamine, releasing free N-acetylmuramic acid and dipeptide.

Rv3594
Rv3594, (MTCY07H7B.28c), len: 275 aa. Hypothetical protein, highly similar in part with Q9ZX49|GP29 from Mycobacteriophage TM4 (547 aa), FASTA scores: opt: 526,E(): 1.3e-25, (46.25% identity in 186 aa overlap); and Q9FZS0|LYSA|GP2 from Mycobacterium phage Ms6 (384 aa) FASTA scores: opt: 147, E(): 0.064, (33.35% identity in 84 aa overlap).
