Cytotoxic variants of human ribonuclease 1 (RNase 1) identified through analysis of the interaction between RNase 1 and the human ribonuclease inhibitor (hRI) as defined by the three dimensional (3-D) atomic structure of the RNase1 hRI complex are disclosed. Also disclosed is the 3-D structure of the hRI.RNase 1 complex and methods for designing and using the RNase 1 variants.

This invention relates to cytotoxic variants of human ribonuclease 1 (RNase 1) identified through analysis of the interaction between RNase 1 and the human ribonuclease inhibitor (hRI) as defined by the three dimensional (3-D) atomic structure of the RNase1 hRI complex. Also disclosed is the 3-D structure of the hRI&#x2022;RNase 1 complex and methods for designing the RNase 1 variants.

The disclosure relates to recombinant adult human apohemoglobin (apo-rHb) in which the stability has been increased by replacement of an amino acid with a counterpart from another organism, such as a deep sea diving mammal. This mutated apo-rHb may be more stable and/or give higher production yields than unmutated adult human apo-rHb. The mutated apo-rHb may be produced in microorganisms, such asor yeast cells, or animal erythroid cells. Some apo-rHb of the present disclosure may be used as part of a blood substitute.
