Dr List worked on an enzyme called aldolase A. This catalyses what is known as the aldol reaction, an important way of forging molecular bonds between carbon atoms.

利斯特博士研究了一种缩酶A的酶，种酶催化所谓的缩反应，是一种在碳原子之间形成分子键的重。

Aldolase A is made of 350 amino acids, the building blocks of proteins, but the bit that does the work consists of only three of these: lysine, glutamic acid and tyrosine. The rest of the enzyme is packaging.

缩酶A由350种氨基酸组成，些氨基酸是蛋白质的组成成分，但起作用的部分只有三个：赖氨酸、谷氨酸和酪氨酸。剩下的酶是包装的。
