The primary structure of the major parvalbumin (pI = 4.45) from the cargilagenous fish Raja clavata has been determined. The amino acid sequence was deduced by the analysis of peptides derived from tryptic digestion of the oxidized protein. These peptides were aligned by comparison with (a) overlapping peptides produced by limited tryptic and chymotryptic digestion, and (b) by comparison with the known structures of other fish parvalbumins. The molecular evolution of thornback ray parvalbumin is briefly discussed.
已确定来自软骨鱼类皱鳃鲨的主要小白蛋白（等电点 = 4.45）的一级结构。通过对氧化蛋白胰蛋白酶消化产生的肽段进行分析推导氨基酸序列。这些肽段通过与（a）有限胰蛋白酶和胰凝乳蛋白酶消化产生的重叠肽段，以及（b）与其他鱼类小白蛋白的已知结构进行比较来排列。简要讨论了棘背鳐小白蛋白的分子进化。
