Answer #1

Because polar amino acids have amino and carboxylic acid groups as side chains, these will contribute in acid base catalysis. Examples for such amino acids are serine (Ser), threonine (Thr), cysteine (Cys), asparagine (Asn), glutamine (Gln), and tyrosine (Tyr). Proton transfer is the commonest reaction that enzymes perform. Such reactions are typically acid or base catalysed.

The active site of lysozyme contains two amino acid residues essential for catalysis: Glu-35 and Asp-52. The pKa values of the carboxyl side chains of these residues are 6.5 and 4.2, respectively. What is the pH optimum of lysozyme based on the plot of pH versus rate, below? What is the ionization state (protonated or deprotonated) of each residue at this pH optimum? Which of these residues, either Glu-35 or Asp-52 act as a base in the catalytic mechanism, consistent...

Proteins are long-chains of amino acids linked together. In solution, these chains tend to fold in certain ways to give the protein a structure. This folding depends on the intermolecular forces (IMFs) between water (or other molecules) and the various amino acid side-chains, as well as the IMFs between different side chains. 1.The amino acid asparagine has a melting point of 241oC whereas that of isoleucine is 295oC. Explain this difference on the basis of IMFs. HINT: it may not...
