Phylogeny of the mammalian heme peroxidases before treatment for long branch attraction and after treatment. (a) Initial unresolved ML tree for mammalian heme peroxidases and peroxidasin from Pan troglodytes and Gallus gallus from the entire dataset. The bootstrap support values from 1000 replicates are shown on all nodes. (b) Resolved phylogeny following site stripping, the cow sequence for LPO can be seen to take an unusual place on the phylogeny.
