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.

artEHypothetical protein; Transpeptidase that recognizes and modifies its substrate by proteolytic cleavage of a sorting signal. Following cleavage, a covalent intermediate is formed via a thioester bond between the archaeosortase and its substrate, which is then transferred and covalently attached to the cell membrane. (184 aa)    
Predicted Functional Partners:
thiL
Thiamine monphosphate kinase (thiL); Catalyzes the ATP-dependent phosphorylation of thiamine- monophosphate (TMP) to form thiamine-pyrophosphate (TPP), the active form of vitamin B1; Belongs to the thiamine-monophosphate kinase family.
  
    0.950
rtcA
Hypothetical protein; 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).
  
    0.784
trm4
Proliferating-cell nucleolar antigen, FMU/NOL1/NOP2 family; Catalyzes AdoMet-dependent formation of m5C in tRNA. Cytidine residue at either position 40 or position 48 is likely to be methylated; Belongs to the class I-like SAM-binding methyltransferase superfamily. RsmB/NOP family.
       0.696
MJ_0024
Conserved 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).
       0.667
MJ_0871
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 39.58; identified by sequence similarity; putative.
   
    0.593
MJ_0880
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 26.24; identified by sequence similarity; putative.
   
    0.479
bioB
Biotin synthetase (bioB); Catalyzes the conversion of dethiobiotin (DTB) to biotin by the insertion of a sulfur atom into dethiobiotin via a radical-based mechanism; Belongs to the radical SAM superfamily. Biotin synthase family.
