The determination of the first 33 amino acids of the Cd-binding-protein (MP II) of Nereis diversicolor (Annelida, Polychaeta) shows a homology of 79 and 61% with 2 respiratory proteins of sipunculids, respectively the myohemerythrin and the hemerythrin. The positive reaction obtained by immunocytochemistry over the hemerythrocytes of Sipunculus nudus using antibodies raised against MP II and the presence of iron on the MP II reinforce this similarity.
对多毛纲沙蚕（环节动物门，多毛纲）镉结合蛋白（MP II）前33个氨基酸的测定表明，它与星虫动物的两种呼吸蛋白，即肌血球素和血球素分别具有79%和61%的同源性。使用针对MP II产生的抗体，通过免疫细胞化学方法在裸体方格星虫的血红细胞上获得的阳性反应以及MP II上铁的存在进一步证实了这种相似性。
