Question 19

A copper-containing oxygen transport protein from a deep-sea hydrothermal vent tube worm is a quaternary protein consisting of three α\alphaα-polypeptide chains and three β\betaβ-polypeptide chains.

The number of amino acids in each of the β\betaβ-polypeptide chains is 8.235%8.235\%8.235% greater than in each of the α\alphaα-polypeptide chains. Each α\alphaα-polypeptide chain contains 170170170 amino acids.

Calculate the total number of amino acids in this entire quaternary protein. Give your answer to the nearest whole number.
