abstract Some lactic acid bacteria contain a tyrosine decarboxylase (TDC) which converts tyrosine to tyramine, a biogenic amine frequently encountered in fermented food and wine. Purification and microsequencing of the TDC of Lactobacillus brevis IOEB 9809 allowed us to determine a partial sequence of the TDC gene encoding 264 amino acids of the enzyme. Analysis of this protein sequence revealed typical features of pyridoxal phosphate-dependent amino acid decarboxylases while not any known decarboxylase was closely related to the TDC of L. brevis IOEB 9809. In addition, we could detect other L. brevis strains carrying a TDC gene in a rapid assay based on the polymerase chain reaction.
