Studies on Rat Liver Catalase

Abstract
The amino acid composition of purified rat liver catalase was determined by ion exchange chromatography using a Beckman Spinco analyzer as follows (in grams of amino acid per 100g. of protein): alanine, 5.88; glycine, 4.36; valine, 6.76; leucine, 6.93; isoleucinc, 4.26; proline, 7.95; phenylalanine, 8.27; tyrosine, 5.67; tryptophan, 2.64; serine, 4.29; threonine, 5.00; cysteine, 0.37; half cystine, 0.59; methionine, 3.01; arginine, 8.54; histidine, 4.90; lysine, 7.45; aspartic acid, 14.89; glutamic acid, 13.27; amide NH3, 2.05.
