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

Score
MJ_0806X-pro aminopeptidase (pepQ); Similar to SP:P46545 PID:1150454 PID:609078 percent identity: 33.33; identified by sequence similarity; putative. (347 aa)    
Predicted Functional Partners:
MJ_0807
Conserved hypothetical protein; Similar to GB:AE000782 percent identity: 44.68; identified by sequence similarity; putative; Belongs to the chorismate pyruvate-lyase type 2 family.
       0.857
map
Methionyl aminopeptidase (map); Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val); Belongs to the peptidase M24A family. Methionine aminopeptidase archaeal type 2 subfamily.

rio1
Conserved hypothetical protein; Despite the protein kinase domain is proposed to act predominantly as an ATPase (By similarity).
    
 0.759
guaB
Inosine-5'-monophosphate dehydrogenase, (guaB); Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth. Belongs to the IMPDH/GMPR family.
   
 
 0.757
gatA
Amidase; Allows the formation of correctly charged Gln-tRNA(Gln) through the transamidation of misacylated Glu-tRNA(Gln) in organisms which lack glutaminyl-tRNA synthetase. The reaction takes place in the presence of glutamine and ATP through an activated gamma-phospho-Glu- tRNA(Gln) (By similarity).
   
 
 0.753
eif5a
Translation initiation factor aIF-5A; Functions by promoting the formation of the first peptide bond; Belongs to the eIF-5A family.
  
 
 0.688
MJ_1130
O-sialoglycoprotein endopeptidase (gcp); Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Is a component of the KEOPS complex that is probably involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37. The Kae1 domain likely plays a direct catalytic role in this reaction (By similarity). The Bud32 domain probably displays kinase activity that regulates Kae1 function. In vitro, exhibits low ATPase activity, but does not bind DNA and does [...]

MJ_1411
Glyceraldehyde-3-phosphate dehydrogenase, NADP-dependent (gapN); Involved in F420 biosynthesis through the oxidation of lactaldehyde to lactate. The substrate preference order is propionaldehyde > DL-lactaldehyde, DL-glyceraldehyde > crotonaldehyde > glycolaldehyde > acetaldehyde, acrolein > formaldehyde. No activity was observed towards methylglyoxal or glyceraldehyde-3-phosphate. Has a preference for NAD over NADP.

MJ_0221
H+-transporting ATP synthase, subunit K (atpK); Similar to GB:D16334 GB:X76913 SP:P43457 PID:416405 PID:472919 percent identity: 45.21; identified by sequence similarity; putative.

hisC
Histidinol-phosphate aminotransferase (hisC); Similar to SP:P06986 GB:U02071 GB:X03416 PID:41695 PID:41710 percent identity: 29.00; identified by sequence similarity; putative.
