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

PH1602871aa long hypothetical protein; 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. (871 aa)    
Predicted Functional Partners:
PH1536
142aa long 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.

PH1529
369aa long hypothetical 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).

PH0160
177aa long hypothetical protein; 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).

PH1568
116aa long hypothetical 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).
 
   
 0.846
PH0099
184aa long hypothetical protein; Hydrolyzes RNA 2',3'-cyclic phosphodiester to an RNA 2'- phosphomonoester; Belongs to the 2H phosphoesterase superfamily. ThpR family.
 
   
 0.838
PH0961
275aa long hypothetical translation initiation factor eIF-2 alpha chain; 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.
   
  
 0.830
PH0197
361aa long hypothetical protein; Polynucleotide kinase that can phosphorylate the 5'-hydroxyl groups of both single-stranded RNA (ssRNA) and single-stranded DNA (ssDNA). Exhibits a strong preference for ssRNA.
      
 0.724
PH1622
559aa long hypothetical DNA ligase; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair.
     
 0.707
PH0923
455aa long hypothetical phospho-sugar mutase; Similar to PIR:C64437 percent identity: 41.839 in 455aa; owl:SAFEMD percent identity: 34.259 in 445aa; owl:SAURED percent identity: 34.259 in 445aa. motif=prokaryotic membrane lipoprotein lipid attachment site.
     
 0.705
PH1601
120aa long hypothetical protein; Part of ribonuclease P, a protein complex that generates mature tRNA molecules by cleaving their 5'-ends. Binds RNase P RNA.
