A biochemical polymorphism of coelomic hemerythrin has been found in the sipunculid Golfingia gouldii; the electrophoretically "fast" and "slow" coelomic hemerythrins differ in their oxygen equilibria and by a single peptide in tryptic and chymotryptic "fingerprints." All individuals of this sipunculid have the same vascular hemerythrin, which is electrophoretically different from any of the coelomic hemerythrins. Vascular and coelomic hemerythrins of another sipunculid, Dendrostomum cymodoceae, have quite different "fingerprints." Thus, on the basis of two separate types of evidence the tissue-specific hemerythrins appear to have a distinct genetic basis. The embryological and phylogenetic implications are discussed.
在星虫动物门的有孔虫类 Golfingia gouldii 中发现了体腔血蓝蛋白的生化多态性；电泳上的“快”和“慢”体腔血蓝蛋白在氧平衡和胰蛋白酶及糜蛋白酶“指纹”中的单个肽段上有所不同。这种星虫动物的所有个体都具有相同的血管血蓝蛋白，其电泳与任何一种体腔血蓝蛋白都不同。另一种星虫动物 Dendrostomum cymodoceae 的血管和体腔血蓝蛋白的“指纹”有很大差异。因此，基于两种不同类型的证据，组织特异性血蓝蛋白似乎具有明显的遗传基础。讨论了胚胎学和系统发生学的意义。
