A method of preparing a conditionally active biologic protein by selecting a wild-type biologic protein, evolving the DNA which encodes the wild-type biologic protein using one or more evolutionary techniques to create mutant DNAs, expressing the mutant DNAs in a eukaryotic cell production host to obtain a mutant protein, subjecting the mutant protein and the wild-type protein to an assay under a normal physiological condition and to an assay under an aberrant condition, selecting a conditionally active mutant protein which exhibits at least one of: (a) a decrease in activity in the assay at the normal physiological condition compared to the wild-type protein, and (b) an increase in activity in the assay under the aberrant condition compared to the wild-type protein; and producing the conditionally active biologic protein in the same eukaryotic cell production host used in the expression step.

The present invention relates to mutants of a parent Trichoderma strain, comprising a polynucleotide encoding a polypeptide and one or more (several) genes selected from the group consisting of a first subtilisin-like serine protease gene, a first aspartic protease gene, a trypsin-like serine protease gene, a second subtilisin-like serine protease gene, and a second aspartic protease gene, wherein the one or more (several) genes are modified rendering the mutant strain deficient in the production of one or more (several) enzymes selected from the group consisting of a first subtilisin-like serine protease, a first aspartic protease, a trypsin-like serine protease, a second subtilisin-like serine protease, and a second aspartic protease, respectively, compared to the parent Trichoderma strain when cultivated under identical conditions. The present invention also relates to methods of producing a polypeptide in such mutants and methods for producing such mutants.
