STRINGSTRING
cca protein (Methylobacter tundripaludum) - STRING interaction network
"cca" - Multifunctional CCA protein in Methylobacter tundripaludum
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ccaMultifunctional CCA protein ; 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. Also shows phosphatase, 2’- nucleotidase and 2’,3’-cyclic phosphodiesterase activities. These phosphohydrolase activities are probably involved in the repair of the tRNA 3’-CCA terminus degraded by intracellular RNases (407 aa)    
Predicted Functional Partners:
eno
2-phosphoglycerate dehydratase ; Catalyzes the reversible conversion of 2- phosphoglycerate into phosphoenolpyruvate. It is essential for the degradation of carbohydrates via glycolysis (426 aa)
       
 
  0.820
pnp
Polynucleotide phosphorylase ; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3’- to 5’-direction (692 aa)
   
 
  0.795
hfq
RNA-binding protein Hfq ; RNA chaperone that binds small regulatory RNA (sRNAs) and mRNAs to facilitate mRNA translational regulation in response to envelope stress, environmental stress and changes in metabolite concentrations. Also binds with high specificity to tRNAs (79 aa)
   
 
 
  0.778
Mettu_4019
Putative uncharacterized protein (144 aa)
 
            0.766
birA
Biotin-[acetyl-CoA carboxylase] synthetase ; Acts both as a biotin--[acetyl-CoA-carboxylase] ligase and a biotin-operon repressor. In the presence of ATP, BirA activates biotin to form the BirA-biotinyl-5’-adenylate (BirA-bio- 5’-AMP or holoBirA) complex. HoloBirA can either transfer the biotinyl moiety to the biotin carboxyl carrier protein (BCCP) subunit of acetyl-CoA carboxylase, or bind to the biotin operator site and inhibit transcription of the operon (332 aa)
 
   
  0.753
tilS
tRNA(Ile)-lysidine synthetase ; Ligates lysine onto the cytidine present at position 34 of the AUA codon-specific tRNA(Ile) that contains the anticodon CAU, in an ATP-dependent manner. Cytidine is converted to lysidine, thus changing the amino acid specificity of the tRNA from methionine to isoleucine (451 aa)
 
   
  0.700
rnr
Ribonuclease R ; 3’-5’ exoribonuclease that releases 5’-nucleoside monophosphates and is involved in maturation of structured RNAs (746 aa)
   
 
  0.672
proS
Prolyl-tRNA synthetase ; Catalyzes the attachment of proline to tRNA(Pro) in a two-step reaction- proline is first activated by ATP to form Pro- AMP and then transferred to the acceptor end of tRNA(Pro). As ProRS can inadvertently accommodate and process non-cognate amino acids such as alanine and cysteine, to avoid such errors it has two additional distinct editing activities against alanine. One activity is designated as ’pretransfer’ editing and involves the tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other activity is designated ’posttransfer’ editing and involves de [...] (569 aa)
 
        0.660
tadA
tRNA-specific adenosine deaminase ; Catalyzes the deamination of adenosine to inosine at the wobble position 34 of tRNA(Arg2) (153 aa)
   
   
  0.645
pcnB
Poly(A) polymerase I ; Adds poly(A) tail to the 3’ end of many RNAs, which usually targets these RNAs for decay. Plays a significant role in the global control of gene expression, through influencing the rate of transcript degradation, and in the general RNA quality control (467 aa)
