Fungal enzymic activity degrading 1,4-α- d-glucans to. 1,5- d-anhydrofructose

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...
