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

stf0Conserved protein; Catalyzes the sulfuryl group transfer from 3'- phosphoadenosine-5'-phosphosulfate (PAPS) to trehalose, leading to trehalose-2-sulfate (T2S). The sulfation of trehalose is the first step in the biosynthesis of sulfolipid-1 (SL-1), a major cell wall glycolipid and the most abundant sulfated metabolite found in Mycobacterium tuberculosis, that is a potential virulence factor thought to mediate host-pathogen interactions. (267 aa)    
Predicted Functional Partners:
Rv0296c
Probable sulfatase; Rv0296c, (MTCY63.01c, MTV035.24c), len: 465 aa. Probable sulfatase, possibly an aryl-/steryl-sulfatase or a sulfamidase (sulfohydrolase) (sulphamidase). Similar to various hydrolases e.g. AAG41945.1|AF304053_1|AF304053 heparan N-sulfatase from Mus musculus (502 aa); NP_061292.1|6851181|AAF29460.1|AF153827_1|AF153827 N-sulfoglucosamine sulfohydrolase (sulfamidase) (sulphamidase) from Mus musculus (502 aa); AAG17206.1|AF217203_1|AF217203 heparan sulfate sulfamidase from Canis familiaris (507 aa); P08842|STS_HUMAN|1360652 steryl-sulfatase precursor (steroid sulfatase) [...]

papA2
Possible conserved polyketide synthase associated protein PapA2; Catalyzes the acylation of trehalose-2-sulfate by adding the palmitoyl group at the 2'-position to yield the intermediate trehalose- 2-sulfate-2'-palmitate (SL659) during the cell wall sulfolipid-1 (SL-1) biosynthesis; Belongs to the PapA acyltransferase family.
  
  
 0.909
papA3
Probable conserved polyketide synthase associated protein PapA3; Involved in the biosynthesis of polyacyltrehalose (PAT) which could have a role in anchoring the bacterial capsule. In vitro catalyzes the sequential transfer of two palmitoyl groups onto a single glucose residue of trehalose generating the diacylated product 2,3- diacyltrehalose (trehalose dipalmitate). Although palmitoyl-CoA (PCoA) seems to be the physiological acyl donor, PapA3 can also use docosanoyl (22-carbon saturated fatty acid) coenzyme A as acyl donor.
  
  
 0.793
papA1
Conserved polyketide synthase associated protein PapA1; Catalyzes the acylation of trehalose-2-sulfate-2'-palmitate (SL659) by adding the (hydroxy)phthioceranoyl group at the 3'-position to yield the diacylated intermediate 2-palmitoyl-3-(C43)-phthioceranyl- alpha, alpha'-D-trehalose-2'-sulfate (SL1278) during the cell wall sulfolipid-1 (SL-1) biosynthesis; Belongs to the PapA acyltransferase family.

lprB
Rv1274, (MTCY50.08c), len: 185 aa. Possible lprB,lipoprotein; contains possible N-terminal signal sequence and appropriately positioned prokaryotic lipoprotein lipid attachment site (PS00013). Some similarity to Rv1275. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).
  
    0.635
mmpL8
Conserved integral membrane transport protein MmpL8; Required for the biosynthesis and the transport across the inner membrane of sulfolipid-1 (SL-1), which is a major cell wall lipid of pathogenic mycobacteria. Could also transport SL1278 (2-palmitoyl-3- (C43)-phthioceranyl-alpha, alpha'-D-trehalose-2'-sulfate), which is the precursor of SL-1. Required for virulence.

Rv0210
Hypothetical protein; Rv0210, (MTCY08D5.05), len: 492 aa. Hypothetical unknown protein. Possibly membrane protein; has hydrophobic stretches around aa 333 - 381.
