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

Score
cysDRv1285, (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). (332 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.

subI
Rv2400c, (MTCY253.21), len: 356 aa. Probable subI,sulfate-binding lipoprotein component of sulfate transport system (see citations below), equivalent to Q9CCN3|SUBI|ML0615 (alias Q49748|B1937_F1_11, 358 aa) putative sulphate-binding protein from Mycobacterium leprae (348 aa), FASTA scores: opt: 1775, E(): 2.3e-102, (76.45% identity in 340 aa overlap). Also similar to others and other substrate-binding proteins e.g. P27366|SUBI_SYNP7|SBPA sulfate-binding protein precursor from Synechococcus sp. strain PCC 7942 (Anacystis nidulans R2) (350 aa), FASTA scores: opt: 703, E(): 4.6e-36, (35.6 [...]

cysW
Rv2398c, (MTCY253.23), len: 272 aa. Probable cysW,sulfate-transport integral membrane protein ABC transporter (see citations below), similar to others e.g. Q9K877|CYSW|BH3129 sulfate ABC transporter (permease) from Bacillus halodurans (287 aa), FASTA scores: opt: 765, E(): 4.1e-40, (43.8% identity in 249 aa overlap); P27370|CYSW_SYNP7 sulfate transport system (permease) protein from Synechococcus sp. strain PCC 7942 (Anacystis nidulans R2) (286 aa), FASTA scores: opt: 757, E(): 1.3e-39, (44.3% identity in 264 aa overlap); Q9I6K9|CYSW|PA0281 sulfate transport protein from Pseudomonas ae [...]

cysT
Probable sulfate-transport integral membrane protein ABC transporter CysT; Part of the ABC transporter complex (TC 3.A.1.6.1) involved in sulfate/thiosulfate import.
 
 
 0.974
cysA1
Sulfate-transport ATP-binding protein ABC transporter CysA1; Part of the ABC transporter complex CysAWTP involved in sulfate/thiosulfate import. Responsible for energy coupling to the transport system.

sirA
Ferredoxin-dependent sulfite reductase SirA; Catalyzes the reduction of sulfite to sulfide, a step in the biosynthesis of sulfur-containing amino acids and cofactors. Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
 
  
 0.953
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.

cysH
Probable phosphoadenosine phosphosulfate reductase; Reduction of activated sulfate into sulfite.

cysG
Rv2847c, (MTCY24A1.10), len: 405 aa. Possible cysG,multifunctional enzyme, siroheme synthase containing uroporphyrin-III c-methyltransferase, precorrin-2 oxidase and ferrochelatase. C-terminus highly similar to many uroporphyrin-III c-methyltransferases e.g. Q51720|COBA uroporphyrinogen III methyltransferase from Propionibacterium freudenreichii (257 aa), FASTA scores: opt: 776, E(): 1.5e-39, (48.95% identity in 243 aa overlap); Q9HMY4|UROM|VNG2331G S-adenosyl-L-methionine:uroporphyrinogen III methyltransferase from Halobacterium sp. strain NRC-1 (246 aa), FASTA scores: opt: 704, E(): [...]
