Heme-containing catalase sequences from 20 different organisms representing prokaryotes, fungi, animals, and plants have been compiled for phylogenetic reconstruction. Phylogenies based on distance and parsimony analysis show that fungal and animal catalases can be derived from one ancestor, whereas bacterial catalases fail to form a monophyletic group. Plant catalases appear to form a second class of catalases that arose independently from a possible prokaryotic ancestor.
为了进行系统发育重建，已收集了来自代表原核生物、真菌、动物和植物的20种不同生物体的含血红素过氧化氢酶序列。基于距离和简约分析的系统发育表明，真菌和动物过氧化氢酶可源自一个共同祖先，而细菌过氧化氢酶未能形成一个单系类群。植物过氧化氢酶似乎形成了第二类过氧化氢酶，它们独立起源于一个可能的原核祖先。
