Green indicates kinases that phosphorylate tyrosines in a poly(tyrosine-glutamate) substrate; “blue kinases” phosphorylated the same substrate weakly; “yellow kinases” could not phosphorylate this substrate. a. What correlation do you see between primary structure and substrate preference? b. If you could see the 3D structures for all of these kinases, hypothesize what you would expect to see for all the “green kinases.” c. Hypothesize what you would see when you compared the 3D structure of a “green kinase” and a “blue” one, a “green kinase” and a “yellow” one.
