Stick in the sulfur: The l-cystine β-lyase from P. inhibens is biochemically characterised in terms of the identification of products from the natural substrate, its substrate scope and enzyme kinetics, and by site-directed mutagenesis. The obtained results, together with feeding experiments with ³⁴S-labelled substrates, corroborate a previously suggested mechanism for sulfur incorporation into the antibiotic tropodithietic acid.
