ENTRY       EC 4.2.99.16
NAME        Uracilylalanine synthase
            Willardiine synthase
            Isowillardiine synthase
CLASS       Lyases
            Carbon-oxygen lyases
            Other carbon-oxygen lyases
SYSNAME     O3-Acetyl-L-serine acetate-lyase (adding uracil)
REACTION    O3-Acetyl-L-serine + Uracil = 3-(Uracil-1-yl)-L-alanine + Acetate
SUBSTRATE   O3-Acetyl-L-serine
            Uracil
PRODUCT     3-(Uracil-1-yl)-L-alanine
            Acetate
COMMENT     Both L-willardiine and L-isowillardiine are produced in the
            reaction. Not identical with EC 4.2.99.8.
