Abstract: A novel transformation system in the field of filamentous fungal hosts for expressing and secreting heterologous proteins or polypeptides is described. The invention also covers a process for producing large amounts of polypeptide or protein in an economical manner. The system comprises a transformed or transfected fungal strain of the genus Chrysosporium, more particularly of Chrysosporium lucknowense and mutants or derivatives thereof. It also covers transformants containing Chrysosporium coding sequences, as well expression-regulating sequences of Chrysosporium genes. Also provided are novel fungal enzymes and their encoding sequences and expression-regulating sequences.

Abstract: The invention pertains to novel proteins corresponding to Chrysosporium glycosyl hydrolases of families 7 and 10, exhibiting a minimum aminoacid identity of 70 and 75%, respectively, with the amino acid sequence of SEQ ID No's 2 and 4, and to a protein corresponding to a Chrysosporium glyceraldehyde phosphate dehydrogenase, exhibiting at least 86% amino acid identity with the partial amino acid sequence of SEQ ID No. 6. The invention further relates to nucleic acid sequences encoding these proteins, and especially to promoter sequences regulating the expression of the corresponding genes. The preferred host for expressing these genes is a fungus, especially a Chrysosporium strain.
