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

mptDConserved hypothetical protein; Catalyzes the conversion of 7,8-dihydroneopterin (H2Neo) to 6-hydroxymethyl-7,8-dihydropterin (6-HMD). (121 aa)    
Predicted Functional Partners:
mptE
Conserved 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.
 
  
 0.994
MJ_0409
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ0409.
       0.907
nadA
Quinolinate synthetase (nadA); Catalyzes the condensation of iminoaspartate with dihydroxyacetone phosphate to form quinolinate.
       0.902
MJ_0410
Hypothetical protein; Similar to PID:1174351 percent identity: 32.34; identified by sequence similarity; putative.
       0.778
mptB
Cmp-binding-factor 1 isolog; Cyclic phosphodiesterase that hydrolyzes the cyclic phosphate of 7,8-dihydroneopterin 2',3'-cyclic phosphate (H2N-cP) and converts it to a mixture of 7,8-dihydroneopterin 2'-phosphate (H2N-2'P) and 7,8- dihydroneopterin 3'-phosphate (H2N-3'P). Is also able to utilize other phosphodiesters as substrates in vitro: hydrolysis of bis-pNPP and pNPPC produces nitrophenyl phosphate, and that of 2',3'-cAMP produces 3'-AMP. ATP, 3',5'-cAMP, GTP, 3',5'-cGMP, and 4',5'-cFMN cannot serve as substrates.
      
 0.763
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.
     
 0.753
hisF
Imidazoleglycerol-phosphate synthase, cyclase subunit (hisF); IGPS catalyzes the conversion of PRFAR and glutamine to IGP, AICAR and glutamate. The HisF subunit catalyzes the cyclization activity that produces IGP and AICAR from PRFAR using the ammonia provided by the HisH subunit (By similarity).
       0.739
MJ_1427
Hypothetical protein; Catalyzes the condensation of 4-aminobenzoate (pABA) with 5- phospho-alpha-D-ribose 1-diphosphate (PRPP) to produce beta- ribofuranosylaminobenzene 5'-phosphate (beta-RFA-P).
     
 0.732
purB
Adenylosuccinate lyase (purB); Similar to GB:J02732 SP:P12047 PID:143366 GB:AL009126 percent identity: 42.51; identified by sequence similarity; putative.
     
 0.650
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.
