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

cysQMonophosphatase 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. [...] (267 aa)    
Predicted Functional Partners:
cysN
Sulfate adenylyltransferase subunit 1; ATP sulfurylase may be the GTPase, regulating ATP sulfurylase activity; In the C-terminal section; belongs to the APS kinase family.
 
 
 0.982
cysH
Probable phosphoadenosine phosphosulfate reductase; Reduction of activated sulfate into sulfite.
  
 
 0.968
nrnA
Conserved protein; Bifunctional enzyme which has both oligoribonuclease and pAp- phosphatase activities. Degrades RNA oligonucleotides with a length of 5 nucleotides and shorter, with a preference for 2-mers. Also degrades 24-mers. Converts 3'(2')-phosphoadenosine 5'-phosphate (PAP) to AMP.

cysD
Rv1285, (MTCY373.04), len: 332 aa. Probable cysD,sulfate adenylyltransferase subunit 2 (see Wooff et al.,2002), homology suggests start site at aa 24 or 28, similar to e.g. CYSD_ECOLI|P21156 sulfate adenylate transferase subunit 2 from Escherichia coli (302 aa), FASTA score: opt: 973, E():0, (52.5% identity in 303 aa overlap). Also similar to Mycobacterium tuberculosis Rv2392,3'-phosphoadenylylsulfate reductase. Belongs to the PAPS reductase family. CYSD subfamily. Thought to be differentially expressed within host cells (see Triccas et al., 1999).
