My name is Charles Craik. I'm a professor at the University of California San Francisco. I'm going to be speaking to you on the fundamentals and principles for engineering proteolytic activity. What is protein engineering?

It is the creation of new proteins. The field of protein engineering began in earnest during the early 1980s with the advent of site directed mutagenesis. This powerful new tool provided protein chemists and structural biologists with the ability to alter proteins in a predictable fashion, much in the same way that an engineer can alter his or her surroundings. The techniques for engineering proteins that are predominantly recombinantly based, are established and readily available in various kits from numerous inventors. So I will focus my talk on the applications of protein engineering.

What are some of the goals of protein engineering? Well, one of them is to understand structure-function relationships of proteins. Using protein engineering, you can surgically dissect the relationship between the structure and the function of a protein. Also, you can use protein engineering to create proteins with novel properties. And finally, to define the fundamental roles of de novo protein design, pretty much the holy grail of protein engineering.
