Sometimes, phosphorylation will make a protein more active (for instance, increasing catalysis or letting it bind to a partner). In other cases, phosphorylation may inactivate the protein or cause it to be broken down. [How does a phosphate group do all this?]
Web7. A signaling kinase (kinase A) in a signaling pathway phosphorylates another kinase called kinase B, activating it. Kinase B in turn phosphorylates kinase C (another kinase in the pathway), activating it. Kinase B also phosphorylates phosphatase B, which has kinase B as its substrate. This is an example of: Answer: a. Signal amplification. 8.
