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

mptAConserved 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. (316 aa)    
Predicted Functional Partners:
queD
Conserved hypothetical protein; Catalyzes the conversion of 7,8-dihydroneopterin triphosphate (H2NTP) to 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) and acetaldehyde.

MJ_0774
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ0774.
     
 0.956
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.

moaA
Molybdenum cofactor biosynthesis protein (moaA); Catalyzes the cyclization of GTP to (8S)-3',8-cyclo-7,8- dihydroguanosine 5'-triphosphate; Belongs to the radical SAM superfamily. MoaA family.

MJ_0776
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 33.05; identified by sequence similarity; putative.

tfe
Putative transcription initiation factor (TFIIE, subunit alpha); Transcription factor that plays a role in the activation of archaeal genes transcribed by RNA polymerase. Facilitates transcription initiation by enhancing TATA-box recognition by TATA-box-binding protein (Tbp), and transcription factor B (Tfb) and RNA polymerase recruitment. Not absolutely required for transcription in vitro, but particularly important in cases where Tbp or Tfb function is not optimal. It dynamically alters the nucleic acid-binding properties of RNA polymerases by stabilizing the initiation complex and d [...]

MJ_0108
Pyruvate kinase; Similar to GB:D13095 SP:Q02499 GB:X57859 PID:285623 percent identity: 38.82; identified by sequence similarity; putative.
 
  
  0.848
MJ_0832
Anaerobic ribonucleoside-triphosphate reductase (nrdD); Similar to SP:P28903 GB:L06097 GB:U06195 GB:Z46865 PID:146970 percent identity: 28.17; identified by sequence similarity; putative.
 
  
  0.838
ndk
Nucleoside diphosphate kinase, (ndk); Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.

MJ_0240
Conserved hypothetical protein; Could catalyze the biosynthesis of cyclic AMP (cAMP) from ATP.
