Myoglobin has been identified in the myocardium of the lamprey Petromyzon marinus, one of the most primitive of all vertebrates. This protein was isolated by ammonium sulphate fractionation and purified by successive chromatography on Ultrogel AcA 54, DEAE-Sephadex and CM-23 cellulose. The molecule differs substantially from the monomeric hemoglobins found in the lamprey as evidenced by its elution profile on DEAE-Sephadex and the fingerprint pattern of its enzymically-produced peptides. The functional significance of this protein in Agnatha is discussed.
在七鳃鳗（Petromyzon marinus）的心肌中已鉴定出肌红蛋白，七鳃鳗是所有脊椎动物中最原始的物种之一。该蛋白质通过硫酸铵分级分离法分离，并通过在Ultrogel AcA 54、DEAE - 葡聚糖凝胶和CM - 23纤维素上连续色谱法进行纯化。该分子与七鳃鳗中发现的单体血红蛋白有很大不同，这一点从其在DEAE - 葡聚糖凝胶上的洗脱图谱及其酶促产生的肽的指纹图谱中可以看出。本文讨论了这种蛋白质在无颌类动物中的功能意义。
