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

mtiPS-methyl-5'-thioinosine phosphorylase; 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. (256 aa)    
Predicted Functional Partners:
dadD
5'-deoxyadenosine deaminase; 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, whereupon the 5'- [...]

SCM56237.1
Putative methylthioribose-1-phosphate isomerase {ECO:0000255|HAMAP-Rule:MF_01678}; 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.

rtcB
tRNA-splicing ligase that acts by directly joining spliced tRNA halves to mature-sized tRNAs by incorporating the precursor-derived splice junction phosphate into the mature tRNA as a canonical 3',5'-phosphodiester. May act as an RNA ligase with broad substrate specificity, and may function toward other RNAs. Binds 2 manganese ions per subunit. steps, with 2',3'-cyclic phosphate termini being hydrolyzed to 3'-P termini in a step that precedes 3'-P activation with GMP. In the first nucleotidyl transfer step, RtcB reacts with GTP to form a covalent RtcB-histidine-GMP intermediate with re [...]

SCM55755.1
Hypothetical Protein.
       0.846
SCM55762.1
Protein archease; Activates the tRNA-splicing ligase complex by facilitating the enzymatic turnover of catalytic subunit RtcB. Acts by promoting the guanylylation of RtcB, a key intermediate step in tRNA ligation. Can also alter the NTP specificity of RtcB such that ATP, dGTP or ITP is used efficiently.

guaAB
GMP synthase [glutamine-hydrolyzing] subunit B; Catalyzes the synthesis of GMP from XMP.
 
 
 0.721
fucA
Catalyzes the cleavage of L-fuculose 1-phosphate to glycerone phosphate and L-lactaldehyde. (S)-lactaldehyde. Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence=; Note=Binds 1 zinc ion per subunit; lactaldehyde and glycerone phosphate from L-fucose: step 3/3. subfamily; sp|P44777|FUCA_HAEIN;evalue=5e-024; PctID=36.61; score=110.

hpt
Hypoxanthine/guanine phosphoribosyltransferase {ECO:0000255|HAMAP-Rule:MF_01467}; 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.
  
 
 0.679
upp
Uracil phosphoribosyltransferase {ECO:0000255|HAMAP-Rule:MF_01218}; Catalyzes the conversion of uracil and 5-phospho-alpha-D- ribose 1-diphosphate (PRPP) to UMP and diphosphate.
