GGH2

Gene
GGH2
Protein
Gamma-glutamyl hydrolase 2
Organism
Arabidopsis thaliana
Length
347 amino acids
Function
Cleaves the polyglutamate sidechains of folate polyglutamates in the vacuole. Is important for polyglutamyl tail length determination before vacuolar exit. Plays a role on folate stability and intracellular folate content. Has endopeptidase activity against 4-amino-10-methylpteroyl penta-, tetra-, tri- and di-gamma-L-glutamate substrates and is responsible for the production of folic acid, also called pteroylglutamic acid (PteGlu) from teroylpolyglutamates.
Similarity
Belongs to the peptidase C26 family.
