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

ppnKInorganic 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. (307 aa)    
Predicted Functional Partners:
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).
 
  
 0.986
tlyA
2'-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.
  
  
 0.986
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.
     
 0.984
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).
  
  
 0.984
recN
Probable DNA repair protein RecN (recombination protein N); May be involved in recombinational repair of damaged DNA.
  
  
 0.978
nadE
Glutamine-dependent NAD(+) synthetase NadE (NAD(+) synthase [glutamine-hydrolysing]); Catalyzes the ATP-dependent amidation of deamido-NAD to form NAD. Uses L-glutamine as a nitrogen source. In vitro, can also use ammonia with comparable specific activity.
  
 
 0.959
nadD
Probable nicotinate-nucleotide adenylyltransferase; Catalyzes the reversible adenylation of nicotinate mononucleotide (NaMN) to nicotinic acid adenine dinucleotide (NaAD).
 
 
 0.948
nadR
Possible transcriptional regulatory protein NadR (probably AsnC-family); Rv0212c, (MTCY08D5.07c), len: 323 aa. Possible nadR (alternate gene name: nadI), transcriptional regulator,similar to others e.g. NADR_ECOLI|P27278 transcriptional regulator from Escherichia coli (410 aa), FASTA scores: opt: 377, E (): 1e-17, (31.1% identity in 347 aa overlap). Contains PS00017 ATP/GTP-binding site motif A (P-loop).
  
 
 0.941
cobB-2
Transcriptional regulatory protein; NAD-dependent lysine deacetylase and desuccinylase that specifically removes acetyl and succinyl groups on target proteins. Modulates the activities of several proteins which are inactive in their acylated form (By similarity). Reactivates acetylated acetyl-CoA synthetase (ACS) through an NAD-dependent deacetylation. Is able to ADP-ribosylate itself.
  
 
 0.923
pntAb
Rv0156, (MTCI5.30), len: 110 aa. Probable pntAb,second part of NAD(P) transhydrogenase subunit alpha,integral membrane protein, similar to C-terminus of others e.g. Q59764 nicotinamide nucleotide transhydrogenase subunit PNTAB (139 aa), FASTA scores: opt: 247, E(): 1.9e-11, (45.5% identity in 88 aa overlap).
