Es ist eine unerwartete Entdeckung, die Wissenschaftler:innen des Helmholtz-Instituts Würzburg in Kooperation mit Benson Hill, Inc. (Missouri) und der Utah State University in den USA gemacht haben: Sie haben eine Nuklease, genannt Cas12a2, gefunden, die eine gänzlich neue Art der CRISPR-Immunabwehr darstellt. Im Gegensatz zu jeder anderen bisher bekannten Nuklease des CRISPR-Cas-Immunsystems, geläufig als Ursprung der „Genschere“, zerstört Cas12a2 die DNA, um eine infizierte Zelle abzuschalten. Die Erkenntnisse könnten neue CRISPR-Technologien unter anderem für die molekularbiologische Diagnostik hervorbringen und wurden heute in dem Fachmagazin Nature veröffentlicht.
