the major changes during the process of metamorphosis were ( 1 ) the total contents of alpha- and gamma-crystallins decrease from more than 70 % to less than 60 % and ( 2 ) one of the major beta-crystallin polypeptides increases from less than 1 % to about 6 % and ( 3 ) an amphibian-specific rho-crystallin also increases from about 6 % to more than 10 % of total soluble proteins of the lens .
