Abstract
  1. The preparation and characterization of manganese, iron, cobalt, nickel, copper and zinc metalloporphyrins is described. Ferrihaem was also esterified with pyrid-4-ylpropanol and the derivative characterized as the diester. 2. Complexes of these various porphyrins, as well as protoporphyrin IX, with apomyoglobin were formed and the resulting artificial myoglobins characterized. 3. Very little complex-formation was obtained with nickel, cobalt and manganese metalloporphyrins and apomyoglobin. 4. Myoglobin prepared with copper metalloporphyrin was immunochemically identical with native ferrimyoglobin. All the other artificial myoglobins were less reactive to varying degrees. 5. The changes in antigenic reactivities were attributed to conformational reorganization caused by the different co-ordination tendencies of the various metals or by the modification of the side chains of the haem.
摘要
  1. 描述了锰、铁、钴、镍、铜和锌金属卟啉的制备及表征。高铁血红素也用4-吡啶基丙醇进行酯化,并将该衍生物表征为二酯。2. 这些各种卟啉以及原卟啉IX与脱辅基肌红蛋白形成复合物,并对所得的人工肌红蛋白进行表征。3. 镍、钴和锰金属卟啉与脱辅基肌红蛋白形成的复合物很少。4. 用铜金属卟啉制备的肌红蛋白在免疫化学上与天然亚铁肌红蛋白相同。所有其他人工肌红蛋白在不同程度上反应性较低。5. 抗原反应性的变化归因于各种金属不同的配位倾向或血红素侧链的修饰引起的构象重组。
