ZymoGenetics is a biotechnology/pharmaceutical company based in Seattle, Washington, involved in the development of therapeutic proteins.

The company was founded in 1981 by Professors Earl W. Davie and Benjamin D. Hall of the University of Washington and 1993 Nobel Laureate in Chemistry Michael Smith of the University of British Columbia. Soon after its founding, ZymoGenetics began working on recombinant proteins with Danish company Novo Nordisk, and was acquired by that company in 1988. It was spun off as a public company in 2000. Bristol-Myers Squibb acquired the company in 2010.

ZymoGenetics' headquarters are in the landmark Lake Union Steam Plant building, built from 1914 to 1921 by Seattle City Light, the municipal electric utility.

In the way of speaking it was the first science that ever gained some credibility, though not everyone can fully comprehend it's vastness. It isn't actually as complicated as it sounds when carefully examined.
