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

mshCCysteine: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. (414 aa)    
Predicted Functional Partners:
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.

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
mshA
Glycosyltransferase 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 [...]

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.

cysQ
Monophosphatase CysQ; Phosphatase with a broad specificity. Its primary physiological function is to dephosphorylate 3'-phosphoadenosine 5'- phosphate (PAP) and 3'-phosphoadenosine 5'-phosphosulfate (PAPS). Thus, plays a role in mycobacterial sulfur metabolism, since it can serve as a key regulator of the sulfate assimilation pathway by controlling the pools of PAP and PAPS in the cell. To a lesser extent, is also able to hydrolyze inositol 1-phosphate (I-1-P), fructose 1,6-bisphosphate (FBP) (to fructose 6-phosphate (F-6-P)) and AMP in vitro, but this might not be significant in vivo.

cysE
Probable serine acetyltransferase CysE (sat); Catalyzes the acetylation of serine by acetyl-CoA to produce O-acetylserine (OAS); Belongs to the transferase hexapeptide repeat family.
 
  
 0.816
rpoZ
DNA-directed RNA polymerase subunit omega; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
  
  
 0.789
mrsA
Probable phospho-sugar mutase / MrsA protein homolog; Catalyzes the conversion of glucosamine-6-phosphate to glucosamine-1-phosphate.
 
  
 0.788
gpgS
Probable glucosyl-3-phosphoglycerate synthase GpgS; Involved in the biosynthesis of 6-O-methylglucose lipopolysaccarides (MGLPs). Catalyzes the transfer of a glucose (Glc) moiety from uridine diphosphate (UDP-Glc) to the position 2 of 3- phospho-D-glycerate (3-PGA) to form glucosyl-3-phosphoglycerate (GPG).
