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

MJ_0060Methylthioadenosine phosphorylase (mtaP); Catalyzes the reversible phosphorylation of S-methyl-5'- thioinosine (MTI) to hypoxanthine and 5-methylthioribose-1-phosphate. Involved in the breakdown of S-methyl-5'-thioadenosine (MTA), a major by-product of polyamine biosynthesis. Catabolism of (MTA) occurs via deamination to MTI and phosphorolysis to hypoxanthine. (252 aa)    
Predicted Functional Partners:
dadD
N-ethylammeline chlorohydrolase (trzA); Catalyzes the deamination of three SAM-derived enzymatic products, namely 5'-deoxyadenosine, S-adenosyl-L-homocysteine, and 5'- methylthioadenosine, to produce the inosine analogs. Can also deaminate adenosine. The preferred substrate for this enzyme is 5'- deoxyadenosine, but all these substrates are efficiently deaminated. Likely functions in a S-adenosyl-L-methionine (SAM) recycling pathway from S-adenosyl-L-homocysteine (SAH) produced from SAM-dependent methylation reactions. May also be involved in the recycling of 5'-deoxyadenosine, whereup [...]

MJ_0454
Translation initiation factor aIF-2B, subunit delta (aIF2BD); Catalyzes the interconversion of methylthioribose-1-phosphate (MTR-1-P) into methylthioribulose-1-phosphate (MTRu-1-P). Belongs to the eIF-2B alpha/beta/delta subunits family. MtnA subfamily.
  
 
 0.995
speE
Spermidine synthase (speE); Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine.
  
 
 0.940
fucA
Fuculose-1-phosphate aldolase (fucA); Involved in the biosynthesis of the coenzyme F420 which requires phospholactate produced via the aldol cleavage of L-fuculose 1-phosphate and the NAD(+)-dependent oxidation of (S)-lactaldehyde. Catalyzes the reversible cleavage of L-fuculose 1- phosphate (Fuc1P) to yield dihydroxyacetone phosphate (DHAP) and S- lactaldehyde (Ref.2,. FucA possesses a high specificity for the dihydroxyacetone phosphate (DHAP), but accepts a great variety of different aldehydes such as DL-glyceraldehyde and glycolaldehyde.

MJ_0062
Hypothetical protein; Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Catalyzes the conversion of L-threonine, HCO(3)(-)/CO(2) and ATP to give threonylcarbamoyl-AMP (TC-AMP) as the acyladenylate intermediate, with the release of diphosphate.
  
  
 0.844
hpt
Adenine phosphoribosyltransferase (apt); Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis. Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.
  
 
 0.762
MJ_0392
Conserved hypothetical protein; A site-2 regulated intramembrane protease (S2P) that cleaves type-2 transmembrane proteins within their membrane-spanning domains; its endogenous substrate is unknown. Regulated intramembrane proteolysis (RIP) occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. A membrane-spanning regulatory substrate protein is first cut extracytoplasmically (site-1 protease, S1P), then within the membrane itself (site-2 protease, S2P, this enzyme), while cytoplasmic proteases finish degr [...]

MJ_0667
Thymidine phosphorylase (deoA); Catalyzes the conversion of AMP and phosphate to adenine and ribose 1,5-bisphosphate (R15P). Exhibits phosphorylase activity toward CMP and UMP in addition to AMP. Functions in an archaeal AMP degradation pathway, together with R15P isomerase and RubisCO. Belongs to the thymidine/pyrimidine-nucleoside phosphorylase family. Type 2 subfamily.
     
 0.679
pgi
Glucose-6-phosphate isomerase; Catalyzes the isomerization of glucose-6-P to fructose-6-P.
     
 0.661
MJ_1388
Adenosylhomocysteinase (ahcY); Catalyzes the hydrolysis of S-inosyl-L-homocysteine (SIH) to L-homocysteine (Hcy) and inosine. Likely functions in a S-adenosyl-L- methionine (SAM) recycling pathway from S-adenosyl-L-homocysteine (SAH) produced from SAM-dependent methylation reactions. Can also catalyze the reverse reaction in vitro, i.e. the synthesis of SIH from Hcy and inosine. Is specific for SIH and inosine as it is unable to either hydrolyze SAH or synthesize SAH from adenosine and Hcy. Belongs to the adenosylhomocysteinase family.
