Ein Team der Universität Greifswald und des Helmholtz-Zentrums Berlin (HZB) hat an BESSY II die Struktur eines wichtigen Enzyms ("MHETase") entschlüsselt. Die MHETase wurde in einem Bakterium entdeckt und ist in der Lage, zusammen mit einem zweiten Enzym, der PETase, den weit verbreiteten Kunststoff PET in seine Grundbausteine zu zerlegen. Die 3D-Struktur der MHETase ermöglichte es den Forschern bereits, die Aktivität dieses Enzyms gezielt zu optimieren, um es zusammen mit der PETase für das nachhaltige Recycling von PET zu nutzen. Die Ergebnisse wurden in der Fachzeitschrift Nature Communications veröffentlicht.
