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

mptNRibosomal protein S6 modification protein 1 (rimK); Catalyzes the ATP or GTP-dependent addition of one L- glutamate molecule to tetrahydromethanopterin, producing tetrahydrosarcinapterin. (291 aa)    
Predicted Functional Partners:
dmrX
4Fe-4S iron-sulfur protein; Involved in the biosynthesis of tetrahydromethanopterin, a coenzyme used in methanogenesis. Catalyzes the reduction of dihydromethanopterin (H(2)MPT) to tetrahydromethanopterin (H(4)MPT). Ferredoxin may serve as an electron donor.

MJ_0227
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 40.07; identified by sequence similarity; putative.
   
 0.785
MJ_0619
Conserved hypothetical protein; Is responsible for the addition of methyl groups at C-7 and C-9 of the pterin ring during methanopterin (MPT) biosynthesis. Catalyzes methylation of 7,8-dihydro-6-hydroxymethylpterin, likely using methylenetetrahydromethanopterin as a methyl group donor, via a radical-based mechanism.

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 [...]

MJ_0618
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 41.76; identified by sequence similarity; putative; Belongs to the UPF0235 family.
       0.447
ftr
Formylmethanofuran:tetrahydromethanopterin formyltransferase (ftr); Catalyzes the reversible transfer of a formyl group from formylmethanofuran (formyl-MFR) to tetrahydromethanopterin (H(4)MPT) so as to produce 5-formyl tetrahydromethanopterin (5-formyl-H(4)MPT) and methanofuran (MFR); Belongs to the FTR family.
 
     0.423
fwdA
Formylmethanofuran dehydrogenase, subunit A (tungsten) (fwdA); Similar to PID:871462 GB:AE000666 PID:1890210 percent identity: 68.95; identified by sequence similarity; putative; Belongs to the metallo-dependent hydrolases superfamily. FwdA/FmdA family.
