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

pcaAMycolic acid synthase PcaA (cyclopropane synthase); Involved in the phagosome maturation block (PMB). Catalyzes the conversion of a double bond to a cyclopropane ring at the proximal position of an alpha mycolic acid via the transfer of a methylene group from S-adenosyl-L-methionine. It can use cis, cis 11,14-eicosadienoic acid and linoelaidic acid as substrate. Cyclopropanated mycolic acids are key factors participating in cell envelope permeability, host immunomodulation and persistence. (287 aa)    
Predicted Functional Partners:
Rv0472c
Rv0472c, (MTV038.16c), len: 234 aa. Probable regulatory protein, possibly TetR family, equivalent to CAC31974.1|AL583925 possible TetR-family transcriptional regulator from Mycobacterium leprae (233 aa). Also similar to CAC01492.1|AL391017 putative transcriptional regulatory protein from Streptomyces coelicolor (218 aa); and CAC01371.1|AL390975 putative TetR-family transcriptional regulator from Streptomyces coelicolor (228 aa). Also similar to AL0212|MTV012_65 from Mycobacterium tuberculosis (246 aa), FASTA scores: opt: 327, E(): 1.8e-15, (31.0% identity in 232 aa overlap); and Z95120 [...]

kasB
3-oxoacyl-[acyl-carrier protein] synthase 2 KasB (beta-ketoacyl-ACP synthase) (KAS I); Catalyzes the condensation reaction of fatty acid synthesis by the addition to an acyl acceptor of two carbons from malonyl-ACP.
  
  
 0.601
fadD32
Long-chain-fatty-acid--AMP ligase FadD32; Catalyzes the activation of long-chain fatty acids as acyl- adenylates (acyl-AMP), which are then transferred to the multifunctional polyketide synthase (PKS) for further chain extension. Belongs to the ATP-dependent AMP-binding enzyme family.

Rv0049
Rv0049, (MTCY21D4.12), len: 137 aa. Conserved hypothetical protein. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

fabD
Rv2243, (MTCY427.24), len: 302 aa. FabD (alternate gene name: mtFabD), malonyl CoA-acyl carrier protein transacylase (see citations below), highly similar to e.g. A57356 acyl-CoA carrier protein malonyltransferase from Streptomyces coelicolor (316 aa), FASTA score: opt: 955,E(): 0, (52.6% identity in 304 aa overlap); FABD_HAEIN|P43712 malonyl CoA-acyl carrier protein transacylase from Haemophilus influenzae, FASTA score: (30.5% identity in 308 aa overlap); and FABD_ECOLI|P25715 from Escherichia coli, FASTA score: (31.4% identity in 309 aa overlap). Identified as a substrate for proteas [...]

lprG
Conserved lipoprotein LprG; Probably helps membrane protein Rv1410c (P55) transport triacylglycerides (TAG) across the inner cell membrane into the periplasm; TAG probably regulates lipid metabolism and growth regulation. Binds TAG and transfers it between lipid bilayers, probably to the outer membrane in vivo. Binds di- and triacylated phosphatidyl-myo-inositol mannosides (PIMs), and glycolipid lipoglycan modulins lipoarabinomannan (LAM) and lipomannan (LM), facilitating their recognition by TLR2. Binds LM > PIM6 > ManLAM > PI-LAM > PIM2 (mannose-capped LAM and phospho-myo-inositol-ca [...]

lppM
Probable conserved lipoprotein LppM; A putative lipoprotein that seems to be specialized for the initial steps of macrophage infection. A non-acylated fragment (residues 26-185) binds phosphatidyl-myo-inositol mannosides (PIMs). Limits, in a TLR2-dependent fashion, bacterial uptake by host (mouse); this effect may be mediated by nonacylated fragment 26-185. Plays a TLR2-dependent role in host phagosome maturation arrest. Plays a TLR2-independent role in chemokine production during the first 24 hours of mouse infection.

Rv0470A
Rv0470A, len: 146 aa. Hypothetical unknown protein. GC plot suggests CDS for Cys-rich protein, could possibly be continuation of Rv0471c but no frameshift found to allow this. Sequence same in Mycobacterium bovis and Mycobacterium tuberculosis strain CDC1551. Weak hits to Cys-rich region (aa 258-314) of D63395|D63395_1 mRNA for NOTCH4 from Homo sapiens (1095 aa), FASTA scores: opt: 132,E(): 1.1, (39.35% identity in 61 aa overlap).
