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

snzPPossible pyridoxine biosynthesis protein SnzP; Catalyzes the formation of pyridoxal 5'-phosphate from ribose 5-phosphate (RBP), glyceraldehyde 3-phosphate (G3P) and ammonia. The ammonia is provided by the PdxT subunit. Can also use ribulose 5- phosphate and dihydroxyacetone phosphate as substrates, resulting from enzyme-catalyzed isomerization of RBP and G3P, respectively. Belongs to the PdxS/SNZ family. (299 aa)    
Predicted Functional Partners:
snoP
Probable glutamine amidotransferase SnoP; Catalyzes the hydrolysis of glutamine to glutamate and ammonia as part of the biosynthesis of pyridoxal 5'-phosphate. The resulting ammonia molecule is channeled to the active site of PdxS.
 0.999
pdxH
Pyridoxine 5'-phosphate oxidase; Catalyzes the oxidation of pyridoxine 5'-phosphate (PNP) into pyridoxal 5'-phosphate (PLP). Unlike many PNPOx enzymes, Rv2607 does not recognize pyridoxamine 5'-phosphate (PMP) as a substrate.

tesB2
Rv2605c, (MTCY01A10.28), len: 281 aa. Probable tesB2, acyl-CoA thioesterase II, highly similar to others e.g. Q98EG9|MLL4250 from Rhizobium loti (Mesorhizobium loti) (286 aa), FASTA scores: opt: 563, E(): 3.9e-29,(47.75% identity in 287 aa overlap); CAC47767 from Rhizobium meliloti (Sinorhizobium meliloti) (294 aa), FASTA scores: opt: 553, E(): 1.8e-28, (49.3% identity in 280 aa overlap); P23911|TESB_ECOLI|B0452 from Escherichia coli strain K12 (285 aa), FASTA scores: opt: 487, E(): 3.1e-24,(41.9% identity in 277 aa overlap); etc. Also similar to O06135|TESB1|Rv1618|MTCY01B2.10 acyl-Co [...]

Rv2603c
Highly conserved protein; Rv2603c, (MTCI270A.02), len: 251 aa. Highly conserved protein, equivalent to Q49645|YQ03_MYCLE|ML0475|U1177B|B1177_C2_181 hypothetical 26.6 KDA protein from Mycobacterium leprae (251 aa), FASTA scores: opt: 1514, E(): 2.2e-84, (92.45% identity in 251 aa overlap). Also highly similar to Q9L288|SCL2.11c hypothetical 26.8 KDA protein from Streptomyces coelicolor (250 aa), FASTA scores: opt: 1268, E(): 1.5e-69, (76.7% identity in 249 aa overlap); Q9AE12|YFCA hypothetical structural protein from Corynebacterium glutamicum (Brevibacterium flavum) (251 aa), FASTA sco [...]

tkt
Transketolase Tkt (TK); Catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose-5-phosphate. Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate. Belongs to the transketolase family.

tal
Probable transaldolase Tal; Transaldolase is important for the balance of metabolites in the pentose-phosphate pathway; Belongs to the transaldolase family. Type 2 subfamily.

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.
   
  
 0.823
rbsK
Ribokinase RbsK; Catalyzes the phosphorylation of ribose at O-5 in a reaction requiring ATP and magnesium. The resulting D-ribose-5-phosphate can then be used either for sythesis of nucleotides, histidine, and tryptophan, or as a component of the pentose phosphate pathway.
    
 0.819
prsA
Ribose-phosphate pyrophosphokinase; Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) and of the decaprenylphosphoryl-arabinose (DPA), an essential precursor for the mycobacterial cell wall biosynthesis. Catalyzes the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib- 5-P) to yield phosphoribosyl diphosphate (PRPP) and AMP. It can also use GTP, CTP and UTP as diphosphoryl donors.

gap
Probable glyceraldehyde 3-phosphate dehydrogenase Gap (GAPDH); Catalyzes the oxidative phosphorylation of glyceraldehyde 3- phosphate (G3P) to 1,3-bisphosphoglycerate (BPG) using the cofactor NAD. The first reaction step involves the formation of a hemiacetal intermediate between G3P and a cysteine residue, and this hemiacetal intermediate is then oxidized to a thioester, with concomitant reduction of NAD to NADH. The reduced NADH is then exchanged with the second NAD, and the thioester is attacked by a nucleophilic inorganic phosphate to produce BPG; Belongs to the glyceraldehyde-3-ph [...]
