Protein modification discussion
The combination of protein phosphorylation by kinases and dephosphorylyation by phosphatases can afford a fine level of control over enzyme activity. We discuss protein post-translational modification (ptm) from an information processing perspective ptm at multiple sites on a protein creates a combina. And actually, most protein modifications fall into this category, and the examples we're going to discuss in this video are all post-translational modifications.
