Abstract
The extracellular haemoglobins of Lumbricus and Tylorrhynchus contain 50 and 61 tightly bound calcium atoms per molecule, respectively. In addition, they contain one to four tightly bound copper and zinc atoms. Although the role of the latter is unknown, that of calcium is probably structural, assisting in the maintenance of the native hexagonal bilayer structure.
摘要
蚯蚓和双胸蚓的细胞外血红蛋白每分子分别含有50个和61个紧密结合的钙原子。此外，它们还含有一到四个紧密结合的铜和锌原子。尽管后者的作用尚不清楚，但钙的作用可能是结构性的，有助于维持天然的六边形双层结构。
