RI is also rich in leucine (21.5%, compared to 9% in typical proteins) and commensurately lower in other hydrophobic residues, esp. valine, isoleucine, methionine, tyrosine, and phenylalanine.
RI je isto tako bogat leucinom (21.5%, u poređenju sa 9% kod tipičnih proteina) i ima proporcionalno niži udeo drugih hidrofobnih ostataka, posebno valina, izoleucina, metionina, tirozina, i fenilalanina.
