The enzyme pyrazolylalanine synthase (EC 4.2.1.50) catalyzes the chemical reaction
- L-serine + pyrazole 3-(pyrazol-1-yl)-L-alanine + H2O
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 L-serine hydro-lyase [adding pyrazole 3-(pyrazol-1-yl)-L-alanine-forming]. Other names in common use include β-pyrazolylalaninase, β-(1-pyrazolyl)alanine synthase, and L-serine hydro-lyase (adding pyrazole). It employs one cofactor, pyridoxal phosphate.
