	4.2.1.50
Description	Pyrazolylalanine synthase
Alternative names	beta-(1-Pyrazol-1-yl)-L-alanine synthase; beta-(1-Pyrazolyl)alanine synthase.
Catalyzed reaction	L-serine + pyrazole = 3-(pyrazol-1-yl)-L-alanine + H(2)O.
Cofactor	Pyridoxal-phosphate.
	The enzyme from Citrullus vulgaris may be identical with EC 2.5.1.51. It may also be identical with cysteine synthase (EC 4.2.1.50).
