Previously we reported the amino acid sequences of 4 well-defined sacroplasmic, high-affinity Ca(2+)-binding proteins in the protochordate amphioxus, Branchiostoma lanceolatum [1]. Here we report on the complete amino acid sequence determination of 3 additional minor isoforms. The seven isoforms differ from each other in 9 positions of a contiguous 17-residue-long segment (positions 20-36) and can be classified in a alpha (ASCP I, III and IV) and a beta lineage (ASCP II, V, VI and VII).
此前我们报道了原索动物文昌鱼（Branchiostoma lanceolatum）中4种明确的肌浆高亲和力Ca(2+)结合蛋白的氨基酸序列[1]。在此我们报告另外3种次要同工型的完整氨基酸序列测定结果。这7种同工型在一个连续的17个残基长的片段（第20 - 36位）的9个位置上彼此不同，可分为α谱系（ASCP I、III和IV）和β谱系（ASCP II、V、VI和VII）。
