Some enzymes can be regulated by covalent modification, in which a group is covalently bonded to an amino acid side chain. Phosphorylation of side chains is a common regulatory covalent modification. In this essay, you will explore phosphorylation of side chains.  Compare and contrast the types of interactions a free alcohol side chain such as serine could make with that of a phosphorylated alcohol such as phosphoserine (pSer). Could this modification affect the 3D structure of the protein? How?  Imagine you are trying to separate a protein containing an unphosphorylated S residue from the same protein containing a pSer residue. Discuss how you could use ion-exchange chromatography to separate these two proteins

Question

Some enzymes can be regulated by covalent modification, in which a group is covalently bonded to an amino acid side chain. Phosphorylation of side chains is a common regulatory covalent modification. In this essay, you will explore phosphorylation of side chains.

  1.  Compare and contrast the types of interactions a free alcohol side chain such as serine could make with that of a phosphorylated alcohol such as phosphoserine (pSer). Could this modification affect the 3D structure of the protein? How?
  2.  Imagine you are trying to separate a protein containing an unphosphorylated S residue from the same protein containing a pSer residue. Discuss how you could use ion-exchange chromatography to separate these two proteins
