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

mtnPS-methyl-5-thioadenosine phosphorylase; Catalyzes the reversible phosphorylation of S-methyl-5'- thioadenosine (MTA) to adenine and 5-methylthioribose-1-phosphate. Involved in the breakdown of MTA, a major by-product of polyamine biosynthesis. Responsible for the first step in the methionine salvage pathway after MTA has been generated from S-adenosylmethionine. Has broad substrate specificity with 6-aminopurine nucleosides as preferred substrates; Belongs to the PNP/MTAP phosphorylase family. MTAP subfamily. (274 aa)    
Predicted Functional Partners:
ssnA
Cytosine deaminase.

speE1
Spermidine synthase, SpeE; Involved in the biosynthesis of polyamines which are thought to support the growth of thermophilic microorganisms under high- temperature conditions. It seems that long-chain and branched-chain of polyamines effectively stabilize DNA and RNA, respectively. Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to norspermidine, spermidine and norspermine to yield norspermine, thermospermine and caldopentamine, respectively. It can also synthesize sym-norspermidine (bis(3-aminopropyl)amine) f [...]

Spermidine synthase; Involved in the biosynthesis of polyamines which are thought to support the growth of thermophilic microorganisms under high- temperature conditions. It seems that long-chain and branched-chain of polyamines effectively stabilize DNA and RNA, respectively. Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to 1,3-diaminopropane to yield sym-norspermidine (bis(3-aminopropyl)amine). It can also synthesize thermospermine from spermidine with a very low activity. Belongs to the spermidine/spermine [...]
