Abstract 1,5- d -Anhydrofructose, the precursor of the antibiotic pyrone microthecin in morels and other fungi, is produced in Morchella vulgaris by a novel enzymic activity, presumably a lyasic one, which acts specifically on open-chain 1,4-α- d -glucans; it can be prepared enzymatically in vitro from starch in 40 to 50% yield.
