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

cofDConserved 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. (311 aa)    
Predicted Functional Partners:
cofC
Conserved 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.
 
  
 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.
 
 
 0.997
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_1255
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ1255; Belongs to the glycosyltransferase 28 family.
  
    0.962
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 [...]
     
 0.878
MJ_1258
Archaeal histone A3; Binds and compact DNA (95 to 150 base pairs) to form nucleosome-like structures that contain positive DNA supercoils. Increases the resistance of DNA to thermal denaturation (in vitro).
 
     0.815
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.
 
   
 0.794
MJ_1257
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ1257.
       0.793
MJ_1254
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ1254.
  
    0.787
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.
