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

SSO0432HAM1 protein; 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. (192 aa)    
Predicted Functional Partners:
guaA-2
GMP synthase, PP-ATPase domain (guaA); Catalyzes the synthesis of GMP from XMP.
 
 
 0.957
ndk
Nucleoside diphosphate kinase (NDP kinase) (ndk); Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate.
  
 0.954
guaA
GMP synthase, glutamine amidotransferase domain (guaA); Catalyzes the synthesis of GMP from XMP.
 
 
 0.947
SSO0433
O-sialoglycoprotein endopeptidase; Protein modification.
     
 0.861
kae1
O-sialoglycoprotein endopeptidase; Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Is probably involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37; Belongs to the KAE1 / TsaD family.
     
 0.861
SSO1605
Hypothetical protein; Highest hit: putative phosphoesterase [MJ1445 - Methanococcus jannaschii].
  
  
 0.832
SSO2531
Hypothetical protein; Contains Metallo phosphoesterase motif. Some similarity with MJ1445.
  
  
 0.832
rph
Ribonuclease PH (rph); Catalytic component of the exosome, which is a complex involved in RNA degradation. Has 3'->5' exoribonuclease activity. Can also synthesize heteropolymeric RNA-tails. Binds RNA. Belongs to the RNase PH family. Rrp41 subfamily.
  
    0.824
folE
GTP cyclohydrolase I (folE); Purines.
  
  
 0.822
SSO2415
Dihydropteroate synthase, putative; Cofactor Biosynthesis.
  
  
 0.760
