  2. 1. On Catalytic Mechanisms for Rational Enzyme Design Strategies

    Author : Charlotte Kürten; Per-Olof Syrén; Rudolf Allemann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; catalytic mechanisms; terpene cyclase; triterpene cyclase; solvent dynamics; protein hydration; thermodynamics; quantum tunneling; polycyclization; natural compounds; ? ?-hydrolase; esterase; amidase; enzyme engineering; biocatalysis; Bioteknologi; Biotechnology;

    Abstract : Enzymes enable life by promoting chemical reactions that govern the metabolism of all living organisms. As green catalysts, they have been extensively used in industry. However, to reach their full potential, engineering is often required, which can benefit from a detailed understanding of the underlying reaction mechanism. READ MORE

  4. 2. Protein complexes in chlorophyll biosynthetic enzymes

    Author : Ragna Peterson Wulff; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; mass spectrometry; Rhodobacter capsulatus; barley; cyclase; magnesium chelatase; chlorophyll biosynthetic pathway; Protein complex;

    Abstract : Proteins are found on the inside, in the membrane, on the surface and on the outside of cells. They form complicated structures and they interact with other molecules and proteins. READ MORE

  5. 3. Pituitary adenylate cyclase activating polypeptide : Expression and neurotrophic activity in the rat brain

    Author : Ylva Skoglösa; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; in situ hybridisation; rat; TBI; BDNF; NGF; GDNF; PACAP; PRI; TUNEL; apoptosis; CNS; PNS; neuropeptides; neurotrophic factors; reactive oxygen species; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Abstract : Neurotrophic factors play an important role in regulating naturally occurring cell death during neurogenesis. In addition to classical neurotrophic factors, some neurotransmitters and neuropeptides have been shown to exhibit neurotrophic activities. READ MORE

  6. 4. Aspects of aqueous humor dynamics : Studies in vivo and in vitro

    Author : Maria Samuelsson-Almén; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; Aqneous humor flow; intraocular pressure; adenylate cyclase; nonpigmented ciliary epithelium; pituitary adenylate cyclase-activating polypeptide; vasoactive intestinal polypeptide; dopamine; prostaglandin; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The purpose of the present investigation was to study the effects of PGF2α-l-isopropylester, some neuropeptides, and pharmacological agents on aqueous humor dynamics and intraocular pressure (IOP) in vivo and on adenylate cyclase activity in the nonpigmented ciliary epithelium (NPE) in vitro.Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal polypeptide (VIP) caused a dose-dependent increase in cAMP formation, indicating that the NPE contains receptors for PACAP and VIP coupled to adenylate cyclase activation.
