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

mgtE-2Magnesium transporter; Acts as a magnesium transporter. (450 aa)    
Predicted Functional Partners:
guaA
GMP synthase (glutamine-hydrolyzing) domain protein; Catalyzes the synthesis of GMP from XMP.
  
 
 0.711
guaB
Inosine-5'-monophosphate dehydrogenase; Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
    
 0.623
pepE
Putative dipeptidase E; COG: COG3340; Pfam: PF03575; InterPro: IPR005320; Belongs to the peptidase S51 family.
       0.618
poxB
Thiamine pyrophosphate enzyme, C-terminal TPP binding domain protein; COG: COG0028; Pfam: PF02776,PF00205,PF02775; InterPro: IPR012001; Belongs to the TPP enzyme family.
     
 0.529
purA
Adenylosuccinate synthase; Plays an important role in the de novo pathway of purine nucleotide biosynthesis. Catalyzes the first committed step in the biosynthesis of AMP from IMP; Belongs to the adenylosuccinate synthetase family.
     
 0.459
purH
Phosphoribosylaminoimidazolecarboxamide formyltransferase/IMP cyclohydrolase; COG: COG0138; Pfam: PF02142,PF01808; InterPro: IPR002695.
    
 0.422
rdgB
Non-canonical purine NTP pyrophosphatase, RdgB/HAM1 family; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides XTP (xanthosine triphosphate), dITP (deoxyinosine triphosphate) and ITP. Seems to function as a house-cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
