EC 2.5.1.53

Names

Accepted name:
uracilylalanine synthase
Other names:
O3-acetyl-L-serine acetate-lyase (adding uracil)
isowillardiine synthase
willardiine synthase
3-O-acetyl-L-serine:uracil 1-(2-amino-2-carboxyethyl)transferase
O3-acetyl-L-serine:uracil 1-(2-amino-2-carboxyethyl)transferase
Systematic name:
O-acetyl-L-serine:uracil 1-(2-amino-2-carboxyethyl)transferase

Reaction

Comments:

Both L-willardiine and L-isowillardiine are produced in the reaction. Not identical with EC 2.5.1.47, cysteine synthase.
