2. 1. Trapping Tyrosine Z : Exploring the Relay between Photochemistry and Water Oxidation in Photosystem II

   Author : Johannes Sjöholm; Stenbjörn Styring; Fikret Mamedov; A. William Rutherford; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Photosystem II; Tyrosine Z; EPR; proton-coupled electron transfer; hydrogen bond; pH;

   Abstract : Photosystem II is unique! It remains the only enzyme that can oxidize water using light as energy input. Water oxidation in photosystem II is catalyzed by the CaMn4 cluster. The electrons extracted from the CaMn4 cluster are transferred to P680+ via the tyrosine residue D1-Tyr161 (YZ). READ MORE

4. 2. Non-invasive monitoring of low molecular weight biomarkers relevant to skin inflammation and cancer

   Author : Skaidre Jankovskaja; Tautgirdas Ruzgas; Johan Engblom; György Marko-Varga; Melinda Rezeli; Pawel Lukasz Urban; Malmö universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tryptophan; Kynurenine; Phenylalanine; Tyrosine; Low molecular Weight Biomarkers; Non-Invasive; Skin Surface Sampling; Skin Permeability; Hydrogels; Prussian White; Health and society; Hälsa och samhälle;

   Abstract : Development of skin inflammation and cancer in viable epidermis and dermis involve slow molecular weight (LMW) metabolites. We hypothesize that these LMW compounds can be collected on the surface of the skin and used for non-invasive diagnostics of skin disorders. READ MORE

5. 3. Using de novo design proteins to explore tyrosine radicals and cation-π interactions

   Author : Bruce W. Berry; Cecilia Tommos; Anders Hofer; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; tyrosine; radicals; cation-pi interactions; de novo designed proteins; biochemistry; biophysics; Biochemistry; biokemi;

   Abstract : Redox cofactors and amino-acid free radicals play important roles in biology. Although many of the same cofactors and amino acids that form these radicals are found across a broad range of biological systems, identical cofactors can have different reduction potentials. The local environment plays a role in defining these redox potentials.

6. 4. Signal Transduction by Proline-Rich Tyrosine Kinase Pyk2

   Author : Inga Dikic; Olli Silvennoinen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Protein phosphorylation; tyrosine kinase; Pyk2 FAK; neuronal differentiation; Ras MAP kinase pathway; Oncology; Onkologi; molekylär cellbiologi; Molecular Cellbiology;

   Abstract : The proline-rich tyrosine kinase (Pyk2) together with focal adhesion kinase (FAK) define a family of non-receptor protein tyrosine kinases that are regulated by diverse stimuli. Activation of Pyk2 has been implicated in multiple signaling events, including modulation of ion channels, activation of MAP kinase cascades and apoptotic cell death. READ MORE

7. 5. Signaling for color change in melanophores : and a biosensor application

   Author : Annika M. Karlsson; Samuel Svensson; Margareta Wallin; Linköpings universitet; []
   Keywords : color change; melanophores; tyrosine; phosphorylations; melatonin; nitric oxide; MEDICINE; MEDICIN;

   Abstract : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells. The dark melanophores can either hide colorful cells so that the animal appears dark, or let through colors from underneath. READ MORE
