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

tlyA2'-O-methyltransferase TlyA; Acts as a host evasion factor, that significantly contributes to the pathogenesis of M.tuberculosis by modulating adaptive immune responses by inhibiting host-protective Th1 and Th17 cytokine responses as well as autophagy. Catalyzes the 2'-O-methylation at nucleotides C1409 in 16S rRNA and C1920 in 23S rRNA. Is likely involved in ribosomal biogenesis. Also exhibits hemolytic activity in vitro, by binding with and oligomerizing into host cell membranes. Belongs to the TlyA family. (268 aa)    
Predicted Functional Partners:
ppnK
Inorganic polyphosphate/ATP-NAD kinase PpnK (poly(P)/ATP NAD kinase); Involved in the regulation of the intracellular balance of NAD and NADP, and is a key enzyme in the biosynthesis of NADP. Catalyzes specifically the phosphorylation on 2'-hydroxyl of the adenosine moiety of NAD to yield NADP. It can use ATP and other nucleoside triphosphates as well as inorganic polyphosphate (poly(P)) as a source of phosphorus.

eis
Enhanced intracellular survival protein Eis,GCN5-related N-acetyltransferase; Effector that is released into the host cell and affects host immune responses; it negatively modulates inflammation, macrophage autophagy, and cell death through redox-dependent signaling. Acts as an acetyltransferase. Acetylates 'Lys-55' of dual-specificity protein phosphatase 16 (DUSP16)/mitogen-activated protein kinase phosphatase-7 (MKP-7), a JNK- specific phosphatase; this leads to the inhibition of JNK-dependent autophagy, phagosome maturation, and ROS (reactive oxygen species) generation for enhanced [...]

gyrA
DNA gyrase subunit A; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state, while in the absence of ATP it relaxes supercoiled dsDNA. Also catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Gyrase from M.tuberculosis has higher decatenation than supercoiling activity compared to E.coli; as M.tuberculosis only has 1 type II topoisomerase, gyrase has to fulfill the decatenation function of topoisomerase IV as well. At comparable con [...]

Rv1691
Rv1691, MTCI125.13, len: 250 aa. Conserved hypothetical protein, similar to Q9S210|SCI51.30C|AL109848 Hypothetical protein from Streptomyces coelicolor (210 aa),FASTA score: opt: 556, E(): 6.4e-27, (50.6% identity in 180 aa overlap).
  
  
 0.946
Rv1693
Rv1693, (MTCI125.15), len: 58 aa. Conserved hypothetical protein, shows some similarity to AL583921 hypothetical protein from Mycobacterium leprae (61 aa). Probable coiled-coil from aa 30 to 58. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).
  
  
 0.945
Rv1692
Probable phosphatase; Glycerol-phosphate phosphatase with a preference for D- glycerol 3-phosphate (sn-glycerol 1-phosphate) over L-glycerol 3- phosphate (sn-glycerol 3-phosphate). Is the final enzyme involved in the recycling/catabolism of glycerophospholipid polar heads. To a lesser extent, is also able to act on glycerol 2-phosphate and D- ribulose 5-phosphate, but cannot use D-glyceraldehyde 3-phosphate, dihydroxyacetone-phosphate, UMP or GMP as substrates. Belongs to the HAD-like hydrolase superfamily.

gid
Probable glucose-inhibited division protein B Gid; Specifically methylates the N7 position of guanine in position 518 of 16S rRNA.
  
  
 0.919
recN
Probable DNA repair protein RecN (recombination protein N); May be involved in recombinational repair of damaged DNA.
 
  
 0.917
gyrB
DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state, while in the absence of ATP it relaxes supercoiled dsDNA. . Also catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Gyrase from M.tuberculosis has higher decatenation than supercoiling activity compared to E.coli; as M.tuberculosis only has 1 type II topoisomerase, gyrase has to fulfill the decatenation function of topoisomerase IV as well. At comparable c [...]

whiB7
Probable transcriptional regulatory protein WhiB-like WhiB7; The apo- but not holo-form probably binds DNA (By similarity). Acts as a transcriptional regulator. Probably redox- responsive. Upon overproduction at least 10 other genes are up- regulated, among them are Rv1258c, Rv1988, Rv2301, Rv2416c, Rv2725c and whiB7 itself. Probably redox-responsive. The apo-form has been shown to act as a protein disulfide reductase.
