Wegen seines auffallend weit geoeffneten aktiven Zentrums tauften die Forschenden das Molekuel &bdquo;Pac-Man-Enzym&ldquo;. Die Studie erschien am 2. September 2026 im Fachjournal The ISME Journal.<\/strong><\/p><h3 class=\"wp-block-heading\">Zwei Funktionen in einem Molekuel<\/h3><p class=\"wp-block-paragraph\">Bei dem Molekuel handelt es sich um eine sogenannte Familie-VIII-Esterase, die ueber einen Lipidanker fest an der Zelloberflaeche des Bakteriums sitzt. Sie zerlegt langkettige aliphatische Polyester in ihre Bausteine (Monomere) &ndash; kann aber zugleich den Beta-Lactam-Ring von Penicillin spalten. Diese Doppelfunktion erklaeren die Forschenden mit der strukturellen Verwandtschaft zu Beta-Lactamasen, jenen Enzymen, mit denen Bakterien Antibiotika unschaedlich machen.<\/p><div
