  • Neurospora expression system
    Patent number: 5695965
    Abstract: Neurospora crassa transformations are employed for production of heterologous proteins, where DNA constructs are prepared using a foreign gene under transcriptional and translational regulatory regions functional in Neurospora. A functional signal sequence is provided for secretion of the heterologous gene product. An auxotrophic Neurospora host is employed and transformed by the combination of the subject construct and a complementing gene. The resulting transformants provide for efficient secretion of the heterologous product.
