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

Rv3030Conserved protein; Probable S-adenosylmethionine-dependent methyltransferase required for the 6-O-methylation of the polysaccharide backbone of 6-O- methylglucosyl lipopolysaccharides (MGLP). (274 aa)    
Predicted Functional Partners:
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.
 
  
 0.991
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.
 
  
 0.991
Rv3034c
Possible transferase; Putative acetyltransferase that is probably involved in the biosynthesis of 6-O-methylglucosyl lipopolysaccharides (MGLP).
 
  
 0.953
octT
Unknown 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.
 
  
 0.925
gpgS
Probable glucosyl-3-phosphoglycerate synthase GpgS; Involved in the biosynthesis of 6-O-methylglucose lipopolysaccarides (MGLPs). Catalyzes the transfer of a glucose (Glc) moiety from uridine diphosphate (UDP-Glc) to the position 2 of 3- phospho-D-glycerate (3-PGA) to form glucosyl-3-phosphoglycerate (GPG).
 
  
 0.919
Rv3037c
Rv3037c, (MTV012.52c), len: 358 aa. Conserved hypothetical protein, similar in part to others e.g. O86799|SC6G4.36c from Streptomyces coelicolor (426 aa),FASTA scores: opt: 545, E(): 5.5e-27, (36.15% identity in 354 aa overlap); Q9UZW6|PAB0687 from Pyrococcus abyssi (386 aa), FASTA scores: opt: 262, E(): 3.5e-09, (31.0% identity in 200 aa overlap); Belongs to the methyltransferase superfamily.
   
  
 0.870
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.

fixA
Electron transfer flavoprotein subunit beta; The electron transfer flavoprotein serves as a specific electron acceptor for other dehydrogenases. It transfers the electrons to the main respiratory chain via ETF-ubiquinone oxidoreductase (ETF dehydrogenase) (By similarity).
  
    0.750
Rv3038c
Conserved protein; Rv3038c, (MTV012.53c), len: 327 aa. Conserved protein, equivalent to Q9CBQ9|ML1723 hypothetical protein from Mycobacterium leprae (327 aa), FASTA scores: opt: 1843, E(): 6.1e-108, (80.75% identity in 327 aa overlap). Weak similarity with e.g. Q9KZI3|SCG8A.16 putative methyltransferase from Streptomyces coelicolor (199 aa),FASTA scores: opt: 227, E(): 3.9e-07, (31.95% identity in 191 aa overlap) and O52570 methyltransferase from Amycolatopsis mediterranei (272 aa), FASTA scores: opt: 228, E(): 4.3e-07, (31.7% identity in 164 aa overlap).
