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

mshAGlycosyltransferase MshA; Catalyzes the transfer of an N-acetyl-glucosamine moiety to 1D-myo-inositol 3-phosphate to produce 1D-myo-inositol 2-acetamido-2- deoxy-glucopyranoside 3-phosphate in the mycothiol (MSH) biosynthesis pathway. MSH and WhiB3 are probably part of a regulatory circuit that mediates gene expression upon acid stress (like that found in host macrophage phagosomes). MSH is one of the major redox buffers which protects bacteria against redox stressors and antibiotics; loss of MSH or ergothioneine (ERG, the other major redox buffer in this bacteria) leads to respiratory [...] (480 aa)    
Predicted Functional Partners:
mshB
1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucopyranoside deacetylase; Catalyzes the deacetylation of 1D-myo-inositol 2-acetamido-2- deoxy-alpha-D-glucopyranoside (GlcNAc-Ins) in the mycothiol (MSH) biosynthesis pathway. Shows some amidase activity toward S-conjugates of mycothiol; Belongs to the MshB deacetylase family.
  
 0.986
mshD
GCN5-related N-acetyltransferase, MshD; Catalyzes the transfer of acetyl from acetyl-CoA to desacetylmycothiol (Cys-GlcN-Ins) to form mycothiol. Belongs to the acetyltransferase family. MshD subfamily.
  
   
 0.972
mshC
Cysteine:1D-myo-inosityl 2-amino-2-deoxy--D-glucopyranoside ligase MshC; Catalyzes the ATP-dependent condensation of GlcN-Ins and L- cysteine to form L-Cys-GlcN-Ins; Belongs to the class-I aminoacyl-tRNA synthetase family. MshC subfamily.
  
   
 0.969
mca
Mycothiol conjugate amidase Mca (mycothiol S-conjugate amidase); A mycothiol (MSH, N-acetyl-cysteinyl-glucosaminyl-inositol) S-conjugate amidase, it recycles conjugated MSH to the N-acetyl cysteine conjugate and the MSH precursor. Involved in MSH-dependent detoxification of a number of alkylating agents and antibiotics. Activity is specific for the mycothiol moiety. Has a low but measurable deacetylation activity on GlcNAc-Ins (N-acetyl-glucosaminyl-inositol), and thus can also directly contribute to the production of MSH.

Rv0487
Rv0487, (MTCY20G9.13), len: 183 aa. Conserved hypothetical protein, highly similar to P54139|Y487_MYCLE|U00018_38|ML2442 hypothetical 20.8 KDA protein from Mycobacterium leprae (184 aa), FASTA scores: opt: 760, E(): 2.4 e-34, (73.0% identity in 159 aa overlap). Also highly similar to CAC04041.1|AL391406 conserved hypothetical protein from Streptomyces coelicolor (168 aa); To M.leprae ML2442.
 
     0.898
ethR
Transcriptional regulatory repressor protein (TetR-family) EthR; Involved in the repression of the monooxygenase EthA which is responsible of the formation of the active metabolite of ethionamide (ETH).
      
 0.893
glgB
1,4-alpha-glucan branching enzyme GlgB (glycogen branching enzyme); Essential enzyme that catalyzes the formation of the alpha- 1,6-glucosidic linkages in glucan chains by scission of a 1,4-alpha- linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position. Is involved in the biosynthesis of both glycogen and capsular alpha-D- glucan.
  
 0.815
gmhA
Probable sedoheptulose-7-phosphate isomerase GmhA (phosphoheptose isomerase); Catalyzes the isomerization of sedoheptulose 7-phosphate in D-glycero-D-manno-heptose 7-phosphate; Belongs to the SIS family. GmhA subfamily.
 
  
 0.800
treZ
Maltooligosyltrehalose trehalohydrolase TreZ; Is involved in the biosynthesis of trehalose but not in that of capsular glucan and glycogen.
  
 0.800
Rv0485
Possible transcriptional regulatory protein; Positively regulates the expression of PE13 and PPE18. Can also regulate expression of some other genes. Plays a role in modulation of innate immune responses; Belongs to the ROK (NagC/XylR) family.
