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

egtDConserved hypothetical protein; Catalyzes the SAM-dependent triple methylation of the alpha- amino group of histidine to form hercynine, a step in the biosynthesis pathway of ergothioneine; Belongs to the methyltransferase superfamily. EgtD family. (321 aa)    
Predicted Functional Partners:
egtB
Conserved hypothetical protein; Catalyzes the oxidative sulfurization of hercynine (N- alpha,N-alpha,N-alpha-trimethyl-L-histidine) into hercynyl-gamma-L- glutamyl-L-cysteine sulfoxide, a step in the biosynthesis pathway of ergothioneine. Ergothioneine is an antioxidant that protects mycobacteria from oxidative stress.
 
 0.999
egtC
Conserved hypothetical protein; Catalyzes the hydrolysis of the gamma-glutamyl amide bond of hercynyl-gamma-L-glutamyl-L-cysteine sulfoxide to produce hercynylcysteine sulfoxide, a step in the biosynthesis pathway of ergothioneine. Ergothioneine is an antioxidant that protects mycobacteria from oxidative stress.
  
 0.996
gshA
Glutamate--cysteine ligase EgtA; Catalyzes the synthesis of gamma-glutamylcysteine (gamma-GC). This compound is used as substrate for the biosynthesis of the low-molecular thiol compound ergothioneine (By similarity).
 
  
 0.989
egtE
Conserved hypothetical protein; Probably catalyzes the conversion of hercynylcysteine sulfoxide to ergothioneine. Ergothioneine is an antioxidant that protects mycobacteria from oxidative stress. Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. EgtE subfamily.
  
  
 0.982
hisD
Probable histidinol dehydrogenase HisD (HDH); Catalyzes the sequential NAD-dependent oxidations of L- histidinol to L-histidinaldehyde and then to L-histidine.
