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
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
- O-acetyl-L-serine + uracil = 3-(uracil-1-yl)-L-alanine + acetate
Comments:
Both L-willardiine and L-isowillardiine are produced in the reaction. Not identical with EC 2.5.1.47, cysteine synthase.
