ID   2.5.1.53
DE   uracilylalanine synthase.
AN   isowillardiine synthase.
AN   O(3)-acetyl-L-serine acetate-lyase (adding uracil).
AN   willardiine synthase.
CA   O-acetyl-L-serine + uracil = 3-(uracil-1-yl)-L-alanine + acetate + H(+).
CC   -!- Both L-willardiine and L-isowillardiine are produced in the reaction.
CC   -!- Not identical with EC 2.5.1.47.
CC   -!- Formerly EC 4.2.99.16.
