The C2 sulfonates taurine and isethionate are also present in the anaerobic mammalian gut, where they are converted into toxic H2S by sulfate and sulfite-reducing bacteria. Here the authors characterise the O2-sensitive enzyme IseG that catalyzes the C-S bond cleavage of isethionate and show that IseG also plays a key role in converting taurine into H2S in Bilophila wadsworthia.
