<p> Proteins in this entry belong to the beta-eliminating lyase family and are thought to act as tryptophanases (<db_xref db="EC" dbkey="4.1.99.1"/>) (also known as L-tryptophan indole-lyases). The genes encoding these proteins are, as a rule, found with a tryptophanase leader peptide TnaC (<db_xref db="INTERPRO" dbkey="IPR013439"/>) encoded upstream. </p> Tryptophanase, proteobacteria
