The X-ray structure of the Mucor miehei triglyceride lipase is reported and the atomic model obtained reveals a Ser .. His .. Asp trypsin-like catalytic triad with an active serine buried under a short helical fragment of a long surface loop.
Abstract
True lipases attach triacylglycerols and act at an oil-water interface; they constitute a ubiquitous group of enzymes catalysing a wide variety of reactions, many with industrial potential. But so far the three-dimensional structure has not been reported for any lipase. Here we report the X-ray structure of the Mucor miehei triglyceride lipase and describe the atomic model obtained at 3.1 A resolution and refined to 1.9 A resolution. It reveals a Ser..His..Asp trypsin-like catalytic triad with an active serine buried under a short helical fragment of a long surface loop.

Biochemical characterization of a new thermostable lipase from Bacillus pumilus strain

TL;DR: This newly isolated lipase from bacterial strains isolated from tannery waters in the old medina of Fez is thermostable and it has a significant difference which was observed when the biochemical properties of the Bacillus pumilus lipase were compared to others microbial lipases.

Lipase-Catalyzed Regioselective Acylation and Deacylation of Glucose Derivatives

TL;DR: The lipase from Candida antarctica proved particularly efficient for catalyzing selective hydrolysis in the 1-position of 1,2,3,4,6-penta-O-acetyl-β-D-glucose (β-1), thereby providing an efficient chemo-enzymatic synthesis starting from readily available raw materials.

Molecular Mechanism behind Solvent Concentration-Dependent Optimal Activity of Thermomyces lanuginosus Lipase in a Biocompatible Ionic Liquid: Interfacial Activation through Arginine Switch.

TL;DR: Molecular dynamics simulations of TLL in aqueous solutions of a biocompatible ionic liquid (IL), cholinium glycinate (ChGly), have been carried out to investigate the microscopic reasons for the experimentally observed enhancement in the activity of T LL upon addition of a room temperature IL (RTIL), especially at an optimal concentration.

The Protein Data Bank: a computer-based archival file for macromolecular structures.

TL;DR: The Protein Data Bank is a computer-based archival file for macromolecular structures that stores in a uniform format atomic co-ordinates and partial bond connectivities, as derived from crystallographic studies.

Solvent content of protein crystals.

TL;DR: An analysis of the solvent content of 116 different crystal forms of globular proteins found that in many cases this range will be sufficiently restrictive to enable the probable number of molecules in the crystallographic asymmetric unit to be determined directly from the molecular weight of the protein and the space group and unit cell dimensions of the crystal.

A graphics model building and refinement system for macromolecules

TL;DR: A model building and refinement system is described for use with a Vector General 3400 display that has been used to assist in difference Fourier map interpretation at medium and high resolution, and to build a protein molecule into a multiple isomorphous replacement phased electron density map.

Stereochemically restrained refinement of macromolecular structures.

TL;DR: Some extensions of the current export versions of the programs that have been implemented or are envisioned are described, expected to be important in realizing the goal of producing refined structural models that reproduce the diffraction patterns to within the accuracy of the measured data and which are compatible with prior stereochemical knowledge of macromolecules.

Human lipoprotein lipase complementary DNA sequence

TL;DR: Analysis of the sequence indicates that human lipoprotein lipase, hepaticlipase, and pancreatic lipase are members of a gene family that acts to hydrolyze triglycerides, providing free fatty acids for cells and affecting the maturation of circulating lipoproteins.
