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

octTUnknown protein; Sugar octanoyltransferase likely involved in the biosynthesis of mycobacterial methylglucose lipopolysaccharide (MGLP). Catalyzes the transfer of an octanoyl group from octanoyl-CoA to the C6 OH of the second glucose in diglucosylglycerate (DGG). DGG is the preferred acceptor, but to a lesser extent, GG (glucosylglycerate) can also be used as substrate. DGG and GG are the two earliest intermediates in MGLP biosynthesis. (247 aa)    
Predicted Functional Partners:
gpgP
Glucosyl-3-phosphoglycerate phosphatase GpgP; Involved in the biosynthesis of mycobacterial methylglucose lipopolysaccharides (MGLPs). Catalyzes the dephosphorylation of glucosyl-3-phosphoglycerate (GPG) to glucosylglycerate (GG). GPG is the preferred substrate, but GpgP also exhibits low dephosphorylation activity on mannosyl-3-phosphoglycerate (MPG) and mannosylglucosyl-3- phosphoglycerate (MGPG) in vitro. Shows only trace of phosphoglycerate mutase (PGM) activity.

Rv2417c
Conserved protein; May bind long-chain fatty acids, such as palmitate, and may play a role in lipid transport or fatty acid metabolism.
  
  
 0.973
Rv3034c
Possible transferase; Putative acetyltransferase that is probably involved in the biosynthesis of 6-O-methylglucosyl lipopolysaccharides (MGLP).
 
  
 0.945
Rv3030
Conserved protein; Probable S-adenosylmethionine-dependent methyltransferase required for the 6-O-methylation of the polysaccharide backbone of 6-O- methylglucosyl lipopolysaccharides (MGLP).
 
  
 0.925
Rv3031
Conserved protein; Catalyzes the formation of branch points in alpha-glucans by cleavage of an alpha-1,4 glycosidic bond and subsequent transfer of the cleaved-off oligosaccharide to a new alpha-1,6 position (Probable). Is probably involved in the biosynthesis of 6-O-methylglucosyl lipopolysaccharides (MGLP); Belongs to the glycosyl hydrolase 57 family.
  
  
 0.907
rsfS
Conserved hypothetical protein; Functions as a ribosomal silencing factor. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation. Belongs to the Iojap/RsfS family.
  
    0.889
nadD
Probable nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
  
    0.887
Rv3032
Alpha (1->4) glucosyltransferase; Glucosyltransferase that uses UDP-glucose as the sugar donor to elongate alpha-(1->4)-glucans. Is involved in the biosynthesis of both 6-O-methylglucosyl lipopolysaccharides (MGLP) and glycogen. May also use ADP-glucose as substrate.
 
  
 0.883
lipB
Probable lipoate biosynthesis protein B LipB; Catalyzes the transfer of endogenously produced octanoic acid from octanoyl-acyl-carrier-protein onto the lipoyl domains of lipoate- dependent enzymes. Lipoyl-ACP can also act as a substrate although octanoyl-ACP is likely to be the physiological substrate. Belongs to the LipB family.
  
  
 0.838
Rv0183
Possible lysophospholipase; Involved in the hydrolysis of exogenous host lipids during chronic infection. Catalyzes the hydrolysis of both monoacylglycerols (MAG) and diacylglycerols (DAG). It hydrolyzes 2-MAG, 1-3-MAG and MAG with short, medium and long chain fatty acids such as 1-monobutyroyl- rac-glycerol (MC4), 1-mono-octanoyl-rac-glycerol (MC8), 1-monodecanoyl- rac-glycerol (MC10), 1-monolauroyl-rac-glycerol (MC12), 1- monomyristoyl-rac-glycerol (MC14) and 1-mono-oleyl-rac-glycerol (MC18:1). Also able to hydrolyze DAG with short (DiC6) and medium (DiC10) fatty acid chains, but not [...]
