7. We saw in lecture that Src kinase is regulated by phosphorylation. a. Phosphorylation is a covalent modification. Based on what we learned in lecture, where does this occur in Src kinase? b. How does the addition of a phosphate group affect the overall structure of Src kinase? c. What stabilizes this new structure? d. What are the regulatory consequences of the structural change that results from phosphorylation? Briefly explain your
