They are rate-limiting enzymes that degrade heme into same moles of dehydrobilirubin(biliverdin),CO and Fe.

血红素氧合酶催化血红素降解为的一氧化碳、胆绿素和铁,胆绿素在胆绿素还原酶作用下,迅速生成胆红素。

The porphyrin compound in human body mainly includes hemoglobin, protoheme, protoporphyrin, coproporphyrin, uro-porphyrin and so on.

人中含有的卟啉化合物主要有血红蛋白、血红素、原卟啉、粪卟啉、尿卟啉等。

Moreover, it is find that the optimum length between deuterohemin and His is one residue, and all of the monomers are more active than their corresponding dimmers.

Dh与 His之间隔一个氨基酸是两者在一级结构上的最佳相对位置，结构的酶活力均高于相应的双结构，因此确定了含有亚血红素和组氨酸的最佳过氧化物模拟酶DhHP-6（Dh-AlaHisThrValGluLys）。
