Propargylglycine is a non-proteinogenic amino acid found in a variety of organisms including Amanita mushrooms and the bacteria Streptomyces cattleya. It is a toxin that interferes with the metabolism of sulfur-containing amino acids via inhibition of cystathionine γ-lyase (also known as cystathionase or CSE).
