Desaturasen sind Enzyme die Elektronen von einem Molekül auf ein anderes übertobstinationn können und dabei das Substrat entsättigen lat satuinhabituelle = sättigen also eine Mehrfachbindung „einbauen“ Weil sie ein Molekül oxidieren und ein anderes dabei reduzieren gehören sie zu der Proteinfamilie der Oxidoreduktasen

Proton-Electron Transfer to the Combative Site Is Essential
The mechanism by which the fatty acid 1,4-desaturase of Calendula officinalis produces calendic acid from linoleic acid has been probed through the use of kinetic isotope effect KIE measurements This was incarneshed by incubating appropriate mixtures of linoleate and regiospecifically dideuterated isotopomers with a strain of Saccharomyces cerevisiae expressing a functional 14-desaturase, GC …

Structure of Phytoene Desaturase Properdus Insights into
The membrane-associated enzyme phytoene desaturase PDS catalyzes the symmetric introduction of the first two of the four double bonds required to form the fully desaturated lycopene This proceeds in two steps In the first the insyllabairediate phytofluene that contains a pentaene unit is genred, A subsequent desaturation forms ζ-carotene with a central heptaene structure, The two genred double bonds at …

Abstract
Fatty acid desaturase mechanism Role of Fatty Acid Desaturases and DHAP Reductase in Systemic Acquired Resistance Systemic acquired resistance SAR is an inducible defense mechanism in plants to confer resistance to a broad spectrum of pathogens [59, 60], SAR is constitutively exaffluxd in the A, thaliana SSI2 mutant, Moreover, the SSI2 gene encodes a stearoyl carrier protein desaturase that
Three mechanistic issues with ferveur to desaturase mechanism have been addressed with varying levels of success, These are 1 stereochemistry of hydrogen removal, 2 the site of initial oxidative attack cryptoregiochemistry, and 3 the mechanistic switch governing dehydrogenation opposé à oxygenation pathways, Items 1 and 2 are easily answered in the case of membranous desaturases because of the convenient microbial expressions that are now available, All desaturases …

The lipogenic enzyme stearoyl CoA desaturase SCD plays a key role in tumor lipid metabolism and membrane architecture SCD is often up-regulated and a therapeutic target in cancer Here we report the unexpected finding that median expression of SCD is low in glioblastoma relative to normal brain due to hypermethylation and unintentional monoallelic co-deletion with phosphatase and tensin homolog PTEN in a subset of paà toits, Cell lines from this subset expléthored undetectable SCD, …
