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

cofCConserved hypothetical protein; Guanylyltransferase that catalyzes the activation of phosphoenolpyruvate (PEP) as enolpyruvoyl-2-diphospho-5'-guanosine, via the condensation of PEP with GTP. It is involved in the biosynthesis of coenzyme F420, a hydride carrier cofactor. Is able to utilize other purine nucleotides including ATP, dGTP and ITP as cosubstrates in place of GTP but with a lower activity. Does not display lactate kinase activity. (224 aa)    
Predicted Functional Partners:
cofD
Conserved hypothetical protein; Catalyzes the transfer of the phosphoenolpyruvate moiety from enoylpyruvoyl-2-diphospho-5'-guanosine (EPPG) to 7,8-didemethyl-8- hydroxy-5-deazariboflavin (FO) with the formation of dehydro coenzyme F420-0 and GMP.
 
  
 0.998
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.
 
   
 0.975
cofG
Conserved hypothetical protein; Catalyzes the radical-mediated synthesis of 7,8-didemethyl-8- hydroxy-5-deazariboflavin (FO) from 5-amino-5-(4-hydroxybenzyl)-6-(D- ribitylimino)-5,6-dihydrouracil.

MJ_0886
Molybdenum cofactor biosynthesis protein (moeA); Similar to GB:M21151 SP:P12281 PID:145539 GB:U00096 PID:1651376 percent identity: 34.44; identified by sequence similarity; putative.
       0.952
cofH
Conserved hypothetical protein; Catalyzes the radical-mediated synthesis of 5-amino-5-(4- hydroxybenzyl)-6-(D-ribitylimino)-5,6-dihydrouracil from 5-amino-6-(D- ribitylamino)uracil and L-tyrosine.
 
   
 0.929
mer
N5,N10-methylene-tetrahydromethanopterin reductase (mer); Catalyzes the reversible reduction of methylene-H(4)MPT to methyl-H(4)MPT; Belongs to the mer family.
 
   
 0.839
MJ_0888
Conserved hypothetical protein; Similar to SP:P54501 PID:1303871 GB:AL009126 percent identity: 28.66; identified by sequence similarity; putative.
     
 0.803
fno
Conserved hypothetical protein; Catalyzes the reduction of NADP(+) with F420H(2) via hydride transfer, and the reverse reaction, i.e. the reduction of F420 with NADPH. Probably functions in the regeneration of NADPH required in biosynthetic reactions; Belongs to the F420-dependent NADP reductase family.
 
   
 0.756
aksA
2-isopropylmalate synthase (leuA); Catalyzes the condensation of alpha-ketoglutarate and acetyl- CoA to form trans-homoaconitate. Can also catalyze the condensation of alpha-ketoadipate with acetyl-CoA to form (R)-homo(2)citrate, and the condensation of alpha-ketopimelate with acetyl-CoA to form (R)- homo(3)citrate; Belongs to the alpha-IPM synthase/homocitrate synthase family.
     
 0.721
cofF
Ribosomal 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 [...]
