Abstract

Ovothiols are histidine-derived thiols that were first isolated from marine invertebrates. We have identified a 5-histidylcysteine sulfoxide synthase (OvoA) as the first ovothiol biosynthetic enzyme and characterized OvoAs from Erwinia tasmaniensis and Trypanosoma cruzi . Homologous enzymes are encoded in more than 80 genomes ranging from proteobacteria to animalia.
