    • Novel circular vectors containing a recplicable DNA sequence and DNA sequences encoding all or part of at least two distinct parental polypeptides are disclosed. Such vectors are used in novel processes utilizing in vivo recombination to produce recombined circular vectors containing said replicable DNA sequences and hybrid DNA sequences comprising: (1) a first DNA sequence encoding the amino-terminal portion of a hybrid polypeptide corresponding to a first part of a first parental polypeptide sequence and (2) a second DNA sequence encoding a carboxy-terminal portion of said hybrid polypeptide corresponding to a first part of a second parental polypeptide sequence. The hybrid DNA sequences of such recombined circular vectors can exprress novel hybrid polypeptides such as hybrid enzymes in general and in particular hybrid amylases and proteases. Various other processes are disclosed to isolate the recombined circular vector containing said hybrid DNA sequences.

    • Novel vectors are disclosed for expressing and secreting heterologous polypeptides from filamentous fungi. Such vectors are used in novel processes to express and secrete such heterologous polypeptides. The vectors used for transforming a filamentous fungus to express and secrete a heterologous polypeptide include a DNA sequence encoding a heterologous polypeptide and a DNA sequence encoding a signal sequence which is functional in a secretory system in a given filamentous fungus and which is operably linked to the sequence encoding the heterologous polypeptide. Such signal sequences may be the signal sequence normally associated with the heterologous polypeptides or may be derived from other sources. The vector may also contain DNA sequences encoding a promoter sequence which is functionally recognized by the filamentous fungus and which is operably linked to the DNA sequence encoding the signal sequence. Preferably functional polyadenylation sequences are operably linked to the 3' terminus of the DNA sequence encoding the heterologous polypeptides. Each of the above described vectors are used in novel processes to transform a filamentous fungus wherein the DNA sequences encoding the signal sequence and heterologous polypeptide are expressed. The thus synthesized polypeptide is thereafter secreted from the filamentous fungus.
