A mycotoxin, (E)-ascladiol, was established as a direct precursor of patulin in cell-free preparations of Penicillium urticae patulin-minus mutants J1 and S11, but not S15. Isomerization to a side product, (Z)-ascladiol, was nonenzymatically catalyzed by sulfhydryl compounds.
霉菌毒素(E)-天冬氨酸被确立为无青霉菌青霉病patulin-minus突变体J1和S11的无细胞制剂中的patulin的直接前体,但不是S15。巯基化合物非酶催化异构化为副产物(Z)-天冬醇。
