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.

cofFRibosomal protein S6 modification protein 2 (rimK); Catalyzes the ATP-dependent addition of one alpha-linked L- glutamate molecule to coenzyme gamma-F420-2, producing alpha-F420-3, the major form of coenzyme F420 found in M.jannaschii. Thus, caps the gamma-polyglutamate tail of coenzyme F420 with a terminal alpha-linked glutamate. Prefers ATP to other purine nucleotide triphosphates; GTP gives about 25% of the activity observed with ATP. Cannot catalyze the addition of the following amino acids or analogs: D-glutamate, beta- glutamate, L-aspartate, L-glutamine, L-alpha-aminoadipate, or [...] (290 aa)    
Predicted Functional Partners:
cofE
Conserved hypothetical protein; Catalyzes the GTP-dependent successive addition of two L- glutamates to the L-lactyl phosphodiester of 7,8-didemethyl-8-hydroxy- 5-deazariboflavin (F420-0) to form coenzyme F420-0-glutamyl-glutamate (F420-2), with a gamma-linkage between the two glutamates. Cannot use F420-2 as substrate to add more glutamates. Exhibits maximum activity with GTP, compared with UTP (66%) and dGTP (25%); with ATP, only F420-1 is observed as the product; CTP and TTP support no activity. Belongs to the CofE family.

hisS
histidyl-tRNA synthetase (hisS); Similar to SP:P30053 percent identity: 35.44; identified by sequence similarity; putative; Belongs to the class-II aminoacyl-tRNA synthetase family.
     
 0.686
dacZ
Conserved hypothetical protein; Diadenylate cyclase that catalyzes the condensation of 2 ATP molecules into cyclic di-AMP (c-di-AMP). c-di-AMP is a second messenger for intracellular signal transduction involved in the control of important regulatory processes such as osmoregulation (By similarity).
 
     0.607
rpl23
LSU ribosomal protein L23P (rplW); Binds to 23S rRNA. One of the proteins that surrounds the polypeptide exit tunnel on the outside of the ribosome. Belongs to the universal ribosomal protein uL23 family.
   
   0.603
argB
Acetylglutamate kinase (argB); Catalyzes the ATP-dependent phosphorylation of N-acetyl-L- glutamate; Belongs to the acetylglutamate kinase family. ArgB subfamily.
     
 0.553
rfcS
Activator 1 (replication factor C), 35 KD subunit; Part of the RFC clamp loader complex which loads the PCNA sliding clamp onto DNA; Belongs to the activator 1 small subunits family. RfcS subfamily.
     
 0.506
ths
Thermosome (ths); Molecular chaperone; binds unfolded polypeptides in vitro, and has a weak ATPase activity; Belongs to the TCP-1 chaperonin family.
     
 0.497
argC
N-acetyl-gamma-glutamyl-phosphate reductase (argC); Catalyzes the NADPH-dependent reduction of N-acetyl-5- glutamyl phosphate to yield N-acetyl-L-glutamate 5-semialdehyde. Belongs to the NAGSA dehydrogenase family. Type 1 subfamily.
 
  
 0.492
hacA
3-isopropylmalate dehydratase (leuC); Hydro-lyase with broad substrate specificity for cis- unsaturated tricarboxylic acids. Catalyzes both the reversible dehydration of (R)-homocitrate ((R)-2-hydroxybutane-1,2,4- tricarboxylate) to produce cis-homoaconitate ((Z)-but-1-ene-1,2,4- tricarboxylate), and its hydration to homoisocitrate ((1R,2S)-1- hydroxybutane-1,2,4-tricarboxylate). Is also able to hydrate the analogous longer chain substrates cis-homo(2)-aconitate, cis-homo(3)- aconitate, and even the non-physiological cis-homo(4)-aconitate with similar efficiency. These reactions are pa [...]
