1. Trapping Tyrosine Z : Exploring the Relay between Photochemistry and Water Oxidation in Photosystem II
Sammanfattning : 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). LÄS MER
Sammanfattning : Protein tyrosine kinases play an important role in the regulation of various cellular processes such asgrowth, differentiation and survival. GTK, a novel SRC-like cytoplasmic tyrosine kinase, was recently cloned from a mouse insulinoma cell line and the present work was conducted in order to find a biological function of GTK in insulin producing and neuronal cells.

Sammanfattning : 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. LÄS MER
4. Functional characterization of tyrosine and tryptophan transport in fibroblasts from healthy controls, patients with schizophrenia and bipolar disorder
Sammanfattning : .... LÄS MER
Sammanfattning : 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. LÄS MER
