Crystal Structure of the Lipase from Proteus mirabilisCrystal Structure of the Lipase from Proteus mirabilis
Structural highlights
Publication Abstract from PubMedBacterial lipases from family I.1 and I.2 catalyze the hydrolysis of triacylglycerol between 25-45 degrees C and are used extensively as biocatalysts. The lipase from Proteus mirabilis belongs to the Proteus/psychrophilic subfamily of lipase family I.1 and is a promising catalyst for biodiesel production because it can tolerate high amounts of water in the reaction. Here we present the crystal structure of the Proteus mirabilis lipase, a member of the Proteus/psychrophilic subfamily of I.1lipases. The structure of the Proteus mirabilis lipase was solved in the absence and presence of a bound phosphonate inhibitor. Unexpectedly, both the apo and inhibitor bound forms of P. mirabilis lipase were found to be in a closed conformation. The structure reveals a unique oxyanion hole and a wide active site that is solvent accessible even in the closed conformation. A distinct mechanism for Ca(2+) coordination may explain how these lipases can fold without specific chaperones.
