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.

MJ_1646Pyrimidine biosynthesis protein, putative; Similar to GP:340170 percent identity: 31.30; identified by sequence similarity; putative; Belongs to the purine/pyrimidine phosphoribosyltransferase family. (211 aa)    
Predicted Functional Partners:
purQ
Phosphoribosylformylglycinamidine synthase I, (purQ); Part of the phosphoribosylformylglycinamidine synthase complex involved in the purines biosynthetic pathway. Catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to yield formylglycinamidine ribonucleotide (FGAM) and glutamate. The FGAM synthase complex is composed of three subunits. PurQ produces an ammonia molecule by converting glutamine to glutamate. PurL transfers the ammonia molecule to FGAR to form FGAM in an ATP- dependent manner. PurS interacts with PurQ and PurL and is thought to [...]

hmvA
DNA binding protein; Binds and compact DNA (95 to 150 base pairs) to form nucleosome-like structures that contain positive DNA supercoils. Increases the resistance of DNA to thermal denaturation (in vitro).
     
 0.754
nob1
Ribosomal protein S15A isolog; Toxic component of a type II toxin-antitoxin (TA) system. Processes pre-16S-rRNA at its 3' end (the D-site) to yield the mature 3' end (By similarity); Belongs to the PINc/VapC protein family.
 
     0.750
queE
Coenzyme PQQ synthesis protein III isolog (Haemophilus influenzae}; Catalyzes the complex heterocyclic radical-mediated conversion of 6-carboxy-5,6,7,8-tetrahydropterin (CPH4) to 7-carboxy-7- deazaguanine (CDG), a step common to the biosynthetic pathways of all 7-deazapurine-containing compounds.

lysS
tRNA synthetase, putative; Similar to GB:D26185 SP:P22250 GB:L14580 GB:M55073 PID:143006 percent identity: 35.54; identified by sequence similarity; putative; Belongs to the class-I aminoacyl-tRNA synthetase family.

MJ_1644
Hypothetical protein; Identified by GeneMark; putative; M. jannaschii predicted coding region MJ1644.
       0.657
MJ_0558
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 41.96; identified by sequence similarity; putative.
  
     0.637
hemC
Porphobilinogen deaminase (hemC); Tetrapolymerization of the monopyrrole PBG into the hydroxymethylbilane pre-uroporphyrinogen in several discrete steps.
       0.614
rpl40e
LSU ribosomal protein L40E (CEP52); Similar to PIR:B48470 percent identity: 61.11; identified by sequence similarity; putative; Belongs to the eukaryotic ribosomal protein eL40 family.
  
     0.498
arcS
Alignment in; Is responsible for the final step in the biosynthesis of archaeosine, a modified nucleoside present in the dihydrouridine loop (D-loop) of archaeal tRNA. Catalyzes the conversion of 7-cyano-7- deazaguanine (preQ0)-modified tRNA to archaeosine-tRNA, transforming a nitrile group to a formamidine group. Can use either glutamine, asparagine or ammonium as amino donor.
