摘要：

Neutral lipases constitute one of the most ubiquitous and diverse families of enzymes. The recently solved crystal structures of three lipases show that enzymatic hydrolysis occurs with the assistance of a catalytic triad, which is structurally reminiscent of serine proteinases. However, these lipases only become active at the oil-water interface through a conformational change that exposes the active centre of the enzyme.
