Four unique carboxymethylcysteine-containing peptides were isolated from tryptic and chymotryptic digests of trout muscle actin carboxymethylated with iodo[2-(14)C]acetic acid in 6m-guanidinium chloride. The amino acid sequences of these peptides were determined and showed a high degree of homology with the corresponding sequences from rabbit actin. One of the radioactive peptides was the C-terminal peptide and another sequence probably contained the cysteine residue from the N-terminal region of the protein.
从在6M氯化胍中用碘代[2-(14)C]乙酸羧甲基化的鳟鱼肌肉肌动蛋白的胰蛋白酶和胰凝乳蛋白酶消化物中分离出四种独特的含羧甲基半胱氨酸的肽。测定了这些肽的氨基酸序列,结果显示它们与兔肌动蛋白的相应序列具有高度同源性。其中一种放射性肽是C末端肽,另一个序列可能包含来自该蛋白质N末端区域的半胱氨酸残基。
