Each ionizable group of an amino acid can exist in one of two states, charged or neutral. The electric charge on the functional group is determined by the relationship between its p Ka and the pH of the solution. This relationship is described by the Henderson-Hasselbalch equation. (a) Histidine has three ionizable functional groups. Write the equilibrium equations for its three ionizations and assign the proper p Ka for each ionization. Draw the structure of histidine in each ionization state.

SOLVED: Canavanine is an amino acid similar to arginine (see accompanying figure) that is normally synthesized by some plants. Usually, in plants or animals that don't make canavanine, arginine aminoacyl-tRNA synthetase cannot distinguish between canavanine and arginine, and t R N A^∧v can be charged with canavanine. Incorporation of canvanine in proteins in place of arginine can cause misfolding and destroys protein structure and function. a. Can you think of a reason why a plant might have evo

SOLVED:A histidine is involved in an interaction with a glutamic acid that stabilizes the charged form of the histidine, such that the value of A G^∘ for deprotonation is 15 kJ ·mol^-1 at pH 7.0 and 293 K (calculated using the biochemical standard state). What is the p Ka of this histidine?

In certain bacterial species, pyrrolysine (Pyl), sometimes called amino acid 22, is incorporated into polypeptides through an unusual use of the genetic code: Pyl is specified by UAG triplets in the middle of the open reading frame of certain rare genes. These bacteria have a pyrrolysine tRNA synthetase that attaches Pyl to a tRNA with the anticodon 5^' CUA 3^' (see accompanying diagram). For Pyl to be incorporated into a protein, Pyl-charged tRNA ribosome before translation is terminated. a. Ex

SOLVED:Heparin, a highly negatively charged glycosaminoglycan, is used clinically as an anticoagulant. It acts by binding several plasma proteins, including antithrombin III, an inhibitor of blood clotting. The 1: 1 binding of heparin to antithrombin III seems to cause a conformational change in the protein that greatly increases its ability to inhibit clotting. What amino acid residues of antithrombin III are likely to interact with heparin?

SOLVED:Charged or Not: Does It Make a Difference? Many solutes that must move into and out of cells exist in either a protonated or ionized form, or they have functional groups that can be either protonated or ionized. Simple molecules such as CO2 H3 PO4( phosphoric acid ), and NH3( ammonia) are in this category, as are organic molecules with carboxylic acid groups, phosphate groups, and/or amino groups. (a) Consider ammonia as a simple example of such compounds. What is the charged form of ammo
