True or False: 1. Post-translational modification is usually a quick and reversible way to regulate the activity of proteins. [1] 2. All proteins in any given cell are modified in the presence of the enzyme capable of post-translational modification. [2] 3. Phosphorylation can occur on the side chains of arginine. [3] 4. The enzymes responsible for acetylation are generally called kinases. [4] 5. The most abundant mode of phosphorylation is via two-component systems. [5] 6. There is at least 1 example of a Ser/Thr kinase that is secreted into the host cell from a bacterium during infection. [6] 7. BY kinases phosphorylate threonine residues in the substrate proteins. [7] 8. N-linked glycosylation indicates the attachment of glycan to the hydroxyl group of Ser or Thr. [8]
