title: Anomalous phylogenies based on bacterial catalase gene sequences.
abstract: Phylogenies based on nine prokaryotic catalase sequences demonstrate no relationship to phylogenies based on rDNA sequences or other known criteria. When this observation is considered together with the monophyletic relationship observed for eukaryotic catalase sequences, it seems likely that the catalase gene sequence has migrated repeatedly from eukaryotes to prokaryotes.
