Publikováno v: Food Research International. 107:19-26

Endospores of thermophilic bacilli are a major concern for producers of dairy powders. In this study, we heat treated 10 different spore suspensions at 110 °C in skim milk and skim milk concentrate (36% dry matter) of the species Geobacillus stearot

Determination of the Translational and Rotational Diffusion Coefficients of Rodlike Particles Using Depolarized Dynamic Light Scattering

Autor: Otto Glatter, and Helmut Lindner, Dieter Lehner

Publikováno v: Langmuir. 16:1689-1695

Depolarized dynamic light scattering (DDLS) experiments are reported on three different systems: on tobacco mosaic virus as a well investigated sample; on PEO−PPO−PEO triblock copolymer micelles, which show sphere-to-rod transition with increasin

Characterization of Enzymatically Induced Aggregation of Casein Micelles in Natural Concentration byin SituStatic Light Scattering and Ultra Low Shear Viscosimetry

Autor: Lars Øgendal, Gerhard Fritz, Peder Worning, Otto Glatter, Dieter Lehner, Rogert Bauer

Publikováno v: Journal of Colloid and Interface Science. 213:445-456

The aggregation of casein micelles in undiluted skim milk after the addition of chymosin was studied by static light scattering and ultra low shear viscometry. The static light scattering measurements were made with two different sample thicknesses,

Static Light Scattering on Dense Colloidal Systems: New Instrumentation and Experimental Results

Autor: Gerhard Kellner, Otto Glatter, Heimo Schnablegger, Dieter Lehner

Publikováno v: Journal of Colloid and Interface Science. 201:34-47

Particle sizing of dense colloidal systems is a very practice-oriented problem. Using optical methods multiple scattering often makes the determination of correct particle sizes impossible. We introduce a new static light scattering instrument which

Stability of the hydroxynitrile lyase from Hevea brasiliensis: a fluorescence and dynamic light scattering study

Autor: Andrea Hickel, Herfried Griengl, Dieter Lehner, Marion Graupner, Albin Hermetter, Otto Glatter

Publikováno v: Enzyme and Microbial Technology. 21:361-366

The reasons for the deactivation of the hydroxynitrile lyase (Hnl) from the rubber tree ( Hevea brasiliensis ) at low pH values (below 4.0), and the influence of buffer salts as well as the possible stabilization of the enzyme by additives were inves

Characterization of Heme-deficient Neuronal Nitric-oxide Synthase Reveals a Role for Heme in Subunit Dimerization and Binding of the Amino Acid Substrate and Tetrahydrobiopterin

Autor: Ernst R. Werner, Barbara M. List, Bernd Mayer, Peter Klatt, Silvia Pfeiffer, Hans Peter Bächinger, Kurt Schmidt, Dieter Lehner, Otto Glatter

Publikováno v: Journal of Biological Chemistry. 271:7336-7342

Neuronal nitric-oxide (NO) synthase contains FAD, FMN, heme, and tetrahydrobiopterin as prosthetic groups and represents a multifunctional oxidoreductase catalyzing oxidation of L-arginine to L-citrulline and NO, reduction of molecular oxygen to supe

Structural analysis of porcine brain nitric oxide synthase reveals a role for tetrahydrobiopterin and L-arginine in the formation of an SDS-resistant dimer

Autor: Bernd Mayer, H P Bächinger, Peter Klatt, Otto Glatter, Dieter Lehner, Kurt Schmidt

Publikováno v: The EMBO Journal. 14:3687-3695

Nitric oxide synthases (NOSs), which catalyze the formation of the ubiquitous biological messenger molecule nitric oxide, represent unique cytochrome P-450s, containing reductase and mono-oxygenase domains within one polypeptide and requiring tetrahy

Small-angle X-ray scattering studies on cellobiose dehydrogenase from Phanerochaete chrysosporium

Autor: Peter Zipper, Gunnar Henriksson, Dieter Lehner, Göran Pettersson

Publikováno v: Biochimica et biophysica acta. 1293(1)

Limited proteolysis of cellobiose dehydrogenase (CDH) from the white rot fungus Phanerochaete chrysosporium by papain cleaves the enzyme into two fragments containing flavin (FAD) and heme, respectively. Small-angle X-ray scattering (SAXS) was employ
