    The family of lipases (triacylglycerol-acyl-hydrolases EC 3.1.1.3) constitutes an interesting class of enzymes because of their ability to interact with lipid-water interfaces, their wide range of substrate specificities, and their potential industrial applications. Here we report the first crystal structure of a bacterial lipase, from Pseudomonas glumae. The structure is formed from three domains, the largest of which contains a subset of the alpha/beta hydrolase fold and a calcium site. Asp263, the acidic residue in the catalytic triad, has previously been mutated into an alanine with only a modest reduction in activity.
