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.

mptEConserved hypothetical protein; Catalyzes the transfer of diphosphate from ATP to 6- hydroxymethyl-7,8-dihydropterin (6-HMD), leading to 6-hydroxymethyl- 7,8-dihydropterin diphosphate (6-HMDP); Belongs to the archaeal 6-HMPDK family. (241 aa)    
Predicted Functional Partners:
mptD
Conserved hypothetical protein; Catalyzes the conversion of 7,8-dihydroneopterin (H2Neo) to 6-hydroxymethyl-7,8-dihydropterin (6-HMD).

MJ_0301
Conserved hypothetical protein; Catalyzes the condensation of 6-hydroxymethyl-7,8- dihydropterin pyrophosphate (DHPP) with 4-(beta-D-ribofuranosyl)- aminobenzene-5'-phosphate (beta-RFA-P) to form 7,8-dihydropterin-6- methyl-4-(beta-D-ribofuranosyl)-aminobenzene-5'-phosphate, a precursor in the biosynthesis of 5,6,7,8-tetrahydromethanopterin (H4MPT). To a lesser extent, is able to condense beta-RFA-P with another arylamine, 1-(4-aminophenyl)-1-deoxy-D-ribitol (APDR), to form 7,8-dihydropterin- 6-methyl-1-(4-aminophenyl)-1-deoxy-D-ribitol. Dephosphorylated beta- RFA-P is not a substrate; [...]

MJ_0448
Conserved hypothetical protein; Similar to PID:577190 percent identity: 29.38; identified by sequence similarity; putative; Belongs to the metallo-beta-lactamase superfamily.
    
  0.902
mptA
Conserved hypothetical protein; Converts GTP to 7,8-dihydro-D-neopterin 2',3'-cyclic phosphate, the first intermediate in the biosynthesis of coenzyme methanopterin. It is also able to utilize a variety of GTP analogs as substrates, including GDP, beta,gamma-methylene-GTP and GTP-[gamma- thio]; Belongs to the GTP cyclohydrolase IV family.

MJ_1633
Conserved hypothetical protein; Similar to GP:1652055 percent identity: 37.46; identified by sequence similarity; putative.

ileS
isoleucyl-tRNA synthetase (ileS); Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile). Belongs to the class-I aminoacyl-tRNA synthetase family. IleS type 2 subfamily.

MJ_0060
Methylthioadenosine phosphorylase (mtaP); Catalyzes the reversible phosphorylation of S-methyl-5'- thioinosine (MTI) to hypoxanthine and 5-methylthioribose-1-phosphate. Involved in the breakdown of S-methyl-5'-thioadenosine (MTA), a major by-product of polyamine biosynthesis. Catabolism of (MTA) occurs via deamination to MTI and phosphorolysis to hypoxanthine.

mch
N5,N10-methenyl-tetrahydromethanopterin cyclohydrolase (mch); Catalyzes the reversible interconversion of 5-formyl-H(4)MPT to methenyl-H(4)MPT(+); Belongs to the MCH family.
       0.638
MJ_0107
Dihydropteroate synthase; Unknown. Does not possess dihydropteroate synthase (DHPS) activity since it does not catalyze the condensation of 6- hydroxymethyl-7,8-dihydropterin pyrophosphate (DHPP) and 4- aminobenzoate to form 7,8-dihydropteroate.
