It is planned to determine the three-dimensional structure of carbamoyl phosphate from Escherichia coli, a high energy intermediate used in several biosynthetic pathways. This enzyme catalyzes the formation of carbamoyl phosphate from glutamine, bicarbonate, and ATP, and is one of the first steps in the biosynthesis of pyrimidines. Conditions for flash-freezing of the crystal have been established and a search for heavy atom derivatives has been initiated.

计划确定 来自大肠杆菌的氨基甲酰磷酸，一种高能中间体 用于多种生物合成途径。 这种酶催化 由谷氨酰胺、碳酸氢盐和ATP形成氨基甲酰磷酸， 并且是嘧啶类生物合成的第一步之一。 晶体的快速冷冻条件已经建立， 已经开始寻找重原子衍生物。
