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

rtcBrtcB homolog, intein containing; GTP-dependent RNA ligase that is involved in tRNA splicing and RNA repair. Joins RNA with 2',3'-cyclic-phosphate or 3'-phosphate ends to RNA with 5'-hydroxy ends; Belongs to the RtcB family. (916 aa)    
Predicted Functional Partners:
PAB1946
Hypothetical protein; 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 (By similarity). Chaperone or modulator of proteins involved in DNA or RNA processing. Protects the tRNA (cytosine-5-)- methyltransferase PAB1947 against aggregation and increases its specificity; Belongs to the archease family.
 
 0.994
rtcA
RNA 3'-terminal phosphate cyclase; Catalyzes the conversion of 3'-phosphate to a 2',3'-cyclic phosphodiester at the end of RNA. The mechanism of action of the enzyme occurs in 3 steps: (A) adenylation of the enzyme by ATP; (B) transfer of adenylate to an RNA-N3'P to produce RNA-N3'PP5'A; (C) and attack of the adjacent 2'-hydroxyl on the 3'-phosphorus in the diester linkage to produce the cyclic end product. The biological role of this enzyme is unknown but it is likely to function in some aspects of cellular RNA processing (By similarity).

aif1A
eIF1A translation initiation factor eIF-1A; Seems to be required for maximal rate of protein biosynthesis. Enhances ribosome dissociation into subunits and stabilizes the binding of the initiator Met-tRNA(I) to 40 S ribosomal subunits (By similarity).
 
   
 0.858
PAB0673
Hypothetical protein.
       0.829
aif2A
eIF2A translation initiation factor eIF-2, subunit alpha; eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA; Belongs to the eIF-2-alpha family.
   
  
 0.810
PAB0062
2'-5' RNA ligase; Hydrolyzes RNA 2',3'-cyclic phosphodiester to an RNA 2'- phosphomonoester; Belongs to the 2H phosphoesterase superfamily. ThpR family.
 
   
 0.793
kptA
Probable RNA 2'-phosphotransferase; Removes the 2'-phosphate from RNA via an intermediate in which the phosphate is ADP-ribosylated by NAD followed by a presumed transesterification to release the RNA and generate ADP-ribose 1''-2''- cyclic phosphate (APPR>P). May function as an ADP-ribosylase (By similarity).
 
   
 0.790
rnp4
RNAse P protein subunit RPR2; Part of ribonuclease P, a protein complex that generates mature tRNA molecules by cleaving their 5'-ends.
     
 0.789
PAB0384
Predicted ATPase involved in replication control, Cdc46/MCM familyn.
       0.773
nB
panB 3-methyl-2-oxobutanoate hydroxymethyltransferase (EC 2.1.2.11); Catalyzes the reversible reaction in which hydroxymethyl group from 5,10-methylenetetrahydrofolate is transferred onto alpha- ketoisovalerate to form ketopantoate; Belongs to the PanB family.
