2024-06-18T13:57:05Z urn:hdl:10256/20600 Simultaneous screening of multiple substrates with an unspecific peroxygenase enabled modified alkane and alkene oxyfunctionalisations Knorrscheidt, Anja Soler i Parpal, Jordi Hünecke, Nicole Püllmann, Pascal Garcia Borràs, Marc Weissenborn, Martin J. Alquens Alkenes Compostos aromàtics Aromatic compounds Oxidoreductases Oxidoreductases A high throughput GC-MS approach was developed, permitting the simultaneous analysis of up to three substrates and six products quantitatively from one reaction mixture. This screening approach was applied to site-saturation libraries of the novel unspecific peroxygenaseMthUPO. Using this setup enabled substantial insights from a small mutant library. Enzyme variants were identified exhibiting selective alkene epoxidation and substantially shifted regioselectivities to 2- and 1-octanol formations. Computational modelling rationalised the observed selectivity changes M. J. W, A. K., and N.
