Crystallization and preliminary X-ray diffraction studies of a complex of extracellular lipase from Streptomyces rimosus with the inhibitor 3, 4- dichloroisocoumarin

A recombinant lipase (triacylglycerol acylhydrolase ; EC 3.1.1.3) from the bacterium Streptomyces rimosus was inhibited by the serine protease inhibitor 3, 4-dichloroisocoumarin and crystallized by the hanging-drop vapour-diffusion method at 291 K. The crystals belonged to the monoclinic space group P21, with unit-cell parameters a = 38.1, b = 78.7, c = 56.6 Å, [beta] = 104.5° and probably two molecules in the asymmetric unit. Diffraction data were collected to 1.7 Å resolution using synchrotron radiation on the XRD beamline of the Elettra synchrotron, Trieste, Italy.
