Schematical Illustration (IMAGE) University of Konstanz Caption Schematical illustration of the taurine degradation pathway in anaerobic Bilophila bacteria. The newly discovered glycyl radical enzyme (IslAB) is able to cleave the sulfur-containing group of taurine from its degradation intermediate, isethionate. The sulfite released is then utilized as electron acceptor for anaerobic energy conservation (sulfite respiration), while the toxic hydrogen sulfide (H2S) is produced.
