The enzyme prephenate dehydratase (EC 4.2.1.51) catalyzes the chemical reaction
- prephenate phenylpyruvate + H2O + CO2
This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is prephenate hydro-lyase (decarboxylating; phenylpyruvate-forming). This enzyme is also called prephenate hydro-lyase (decarboxylating). This enzyme participates in phenylalanine, tyrosine and tryptophan biosynthesis.
Structural studies
[edit | edit source]As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2QMX.
