Design Notes

While designing the sequence of the recombinant chitinase, there were several considerations that we needed to keep in mind. Firstly, since we planned to express the chitinase in E. coli, it became necessary that the final molecular weight was less than 100 kDa to enable robust protein folding post expression in the chassis. This imposed a constraint on the size and number of wild-type domains we could join. Secondly, since we aimed to use the chitinase as a therapeutic, the activity of our enzyme as a function of temperature and pH were essential parameters to keep in mind. Our interactions with distinguished crystallographers made us realize that these parameters would depend heavily on the temperature and pH activity curves of the wild-type chitinases we chose. Hence, we decided on wild-type enzymes that retained a significant fraction of their activities at physiological temperatures and pH.
