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.

rtcBPFAM: protein of unknown function UPF0027; SMART: Hedgehog/intein hint domain protein; KEGG: mja:MJ0682 hypothetical protein; Belongs to the RtcB family. (974 aa)    
Predicted Functional Partners:
ACX72609.1
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.
 
  
 0.978
rnz
Ribonuclease Z; Zinc phosphodiesterase, which displays some tRNA 3'- processing endonuclease activity. Probably involved in tRNA maturation, by removing a 3'-trailer from precursor tRNA; Belongs to the RNase Z family.
 
   
 0.782
ACX72116.1
PFAM: DEAD/DEAH box helicase domain protein; helicase domain protein; SMART: DEAD-like helicase; helicase domain protein; KEGG: mfe:Mefer_1401 DEAD/DEAH box helicase domain protein; Belongs to the DEAD box helicase family.
   
 0.766
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.
   
 0.766
endA
tRNA intron endonuclease; Endonuclease that removes tRNA introns. Cleaves pre-tRNA at the 5'- and 3'-splice sites to release the intron. The products are an intron and two tRNA half-molecules bearing 2',3' cyclic phosphate and 5'-OH termini. Recognizes a pseudosymmetric substrate in which 2 bulged loops of 3 bases are separated by a stem of 4 bp.
 
   
 0.763
dys
Deoxyhypusine synthase; Catalyzes the NAD-dependent oxidative cleavage of spermidine and the subsequent transfer of the butylamine moiety of spermidine to the epsilon-amino group of a specific lysine residue of the eIF-5A precursor protein to form the intermediate deoxyhypusine residue.
 
   
 0.755
ACX72873.1
PFAM: nuclease (SNase domain protein); SMART: nuclease (SNase domain protein); KEGG: mja:MJ1439 thermonuclease.
     
 0.747
ACX72817.1
TIGRFAM: RNA methylase, NOL1/NOP2/sun family; PFAM: Fmu (Sun) domain protein; KEGG: mfe:Mefer_1246 RNA methylase, NOL1/NOP2/sun family; Belongs to the class I-like SAM-binding methyltransferase superfamily. RsmB/NOP family.
 
   
 0.723
prf1
eRF1 domain 2 protein; Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA.
