Abstract
The subject invention provides for the production of lactoferrins and lactoferrin polypeptide fragments using the host cells Aspergillus in combination with novel plasmid constructs. More specifically, the subject invention provides novel vector constructs capable of producing lactoferrins and lactoferrin polypeptide fragments in Aspergillus host cells. More particularly, the subject invention provides for novel plasmid constructs suitable for use with Aspergillus and especially Aspergillus awamori, niger and oryzae host cells, which enables them to produce large amounts of recombinant lactoferrins and lactoferrin polypeptide fragments.
