Graphical Abstract

Eine Kombination von NMR-Spektroskopie und Massenspektrometrie lieferte die entscheidenden Informationen bei der Bestimmung der Struktur einer relativ stabilen, durch Licht desaktivierten Form des Cofaktors der Hydrogenase Hmd (siehe Schema). Den Untersuchungen zufolge ist ein Pyridon-Chromophor über eine Phosphatgruppe an GMP gebunden.
