O3-acetyl-L-serine:pyrazole 1-(2-amino-2-carboxyethyl)transferase

O3-acetyl-L-serine + pyrazole = 3-(pyrazol-1-yl)-L-alanine + acetate [RN:R03134]

R03134

O3-acetyl-L-serine [CPD:C00979];
pyrazole [CPD:C00481]

The enzyme is highly specific for acetylserine and pyrazole. Not identical with EC 2.5.1.52 L-mimosine synthase.
