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

rtcBPFAM: protein of unknown function UPF0027; KEGG: pca:Pcar_0019 hypothetical protein; Belongs to the RtcB family. (483 aa)    
Predicted Functional Partners:
ADI32500.1
Protein of unknown function DUF101; 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.

rtcA
RNA 3'-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.

hisS
TIGRFAM: histidyl-tRNA synthetase; KEGG: rak:A1C_02295 histidyl-tRNA synthetase; PFAM: tRNA synthetase class II (G H P and S); Anticodon-binding domain protein; Belongs to the class-II aminoacyl-tRNA synthetase family.
  
  
 0.668
ADI32562.1
PFAM: tRNA intron endonuclease, catalytic domain protein; tRNA intron endonuclease domain protein.
     
 0.652
prf1
eRF1 domain 2 protein; Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA.
  
    0.593
flpA
Fibrillarin; Involved in pre-rRNA and tRNA processing. Utilizes the methyl donor S-adenosyl-L-methionine to catalyze the site-specific 2'-hydroxyl methylation of ribose moieties in rRNA and tRNA. Site specificity is provided by a guide RNA that base pairs with the substrate. Methylation occurs at a characteristic distance from the sequence involved in base pairing with the guide RNA; Belongs to the methyltransferase superfamily. Fibrillarin family.
   
 0.578
kptA
Phosphotransferase KptA/Tpt1; 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.
