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

fnoConserved 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. (223 aa)    
Predicted Functional Partners:
rnz
Conserved hypothetical protein; Zinc phosphodiesterase, which displays some tRNA 3'- processing endonuclease activity. Probably involved in tRNA maturation, by removing a 3'-trailer from precursor tRNA; Belongs to the RNase Z family.

MJ_1536
Thioredoxin reductase (trxB); Similar to GB:U02197 GB:L43967 SP:P47348 PID:1045780 percent identity: 38.93; identified by sequence similarity; putative.
     
 0.877
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.
 
   
 0.801
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.

MJ_1503
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 39.29; identified by sequence similarity; putative.
       0.778
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.
 
   
 0.756
trx
Thioredoxin (trx); Acts to maintain redox homeostasis; functions as a protein disulfide reductase.
     
 0.739
cdhC1
Carbon monoxide dehydrogenase, subunit alpha; Part of a complex that catalyzes the reversible cleavage of acetyl-CoA, allowing autotrophic growth from CO(2). The alpha-epsilon complex generates CO from CO(2), while the beta subunit (this protein) combines the CO with CoA and a methyl group to form acetyl-CoA. The methyl group, which is incorporated into acetyl-CoA, is transferred to the beta subunit by a corrinoid iron-sulfur protein (the gamma-delta complex); Belongs to the CdhC family.
      
 0.731
mjaVR
Hypothetical protein; Recognizes the double-stranded unmethylated sequence GTAC.
       0.711
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.
