参考标题:Stereospecific Synthesis Of Threo- And Erythro-β-Hydroxyglutamic Acid During Kutzneride Biosynthesis 作者:Matthias Strieker,Elizabeth M. Nolan,Christopher T. Walsh,Mohamed A. Marahiel |发布日期:2009.9.23 摘要:D-3-Hydroxyglutamic Acid, Which Is Found In The Threo And Erythro Isomers In Mature Kutznerides. In This Study, Two Putative Nonheme Iron Oxygenase Enzymes, Ktzo And Ktzp, Were Recombinantly Expressed, Characterized Biochemically In Vitro, And Found To Stereospecifically Hydroxylate The Beta-Position Of Glutamic Acid. Ktzo Generates Threo-L-Hydroxyglutamic Acid And Ktzp Catalyzes The Formation Of The Erythro-Isomer
