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_1533Conserved hypothetical protein; Similar to GB:X04021 PID:44719 PID:44720 percent identity: 67.05; identified by sequence similarity; putative. (642 aa)    
Predicted Functional Partners:
cca
tRNA nucleotidyltransferase (cca); Catalyzes the addition and repair of the essential 3'- terminal CCA sequence in tRNAs without using a nucleic acid template. Adds these three nucleotides in the order of C, C, and A to the tRNA nucleotide-73, using CTP and ATP as substrates and producing inorganic pyrophosphate; Belongs to the tRNA nucleotidyltransferase/poly(A) polymerase family. Archaeal CCA-adding enzyme subfamily.
  
   
 0.586
alaS
alanyl-tRNA synthetase (alaS); Catalyzes the attachment of alanine to tRNA(Ala) in a two- step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala) (By similarity). Also functions in trans to edit the amino acid moiety from incorrectly charged Ser-tRNA(Ala), and maybe also from Gly-tRNA(Ala).
 
     0.536
nob1
Ribosomal protein S15A isolog; Toxic component of a type II toxin-antitoxin (TA) system. Processes pre-16S-rRNA at its 3' end (the D-site) to yield the mature 3' end (By similarity); Belongs to the PINc/VapC protein family.
 
     0.530
mer
N5,N10-methylene-tetrahydromethanopterin reductase (mer); Catalyzes the reversible reduction of methylene-H(4)MPT to methyl-H(4)MPT; Belongs to the mer family.
 
     0.520
MJ_0482
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 60.00; identified by sequence similarity; putative.
  
     0.495
MJ_0932
Archaeal histone A2; Binds and compact DNA (95 to 150 base pairs) to form nucleosome-like structures that contain positive DNA supercoils. Increases the resistance of DNA to thermal denaturation (in vitro).
 
     0.485
MJ_0168
Archaeal histone A1; Binds and compact DNA (95 to 150 base pairs) to form nucleosome-like structures that contain positive DNA supercoils. Increases the resistance of DNA to thermal denaturation (in vitro).
 
     0.484
MJ_1258
Archaeal histone A3; Binds and compact DNA (95 to 150 base pairs) to form nucleosome-like structures that contain positive DNA supercoils. Increases the resistance of DNA to thermal denaturation (in vitro).
 
     0.479
MJ_0106
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 38.16; identified by sequence similarity; putative.
  
   
 0.470
MJ_1288
Type II secretion system protein; Similar to GP:1707774 percent identity: 29.44; identified by sequence similarity; putative; Belongs to the GSP E family.
