Fig. 6: G-type lysozymes are widely distributed over the animal tree of life and the only lysozyme of all early branching metazoans except ctenophores.
From: An ancient lysozyme in placozoans participates in acidic extracellular digestion
Overview phylogram of metazoans according to Laumer et al.7 that shows the distribution of the most abundant lysozyme families (closed circles). The status of lysozyme abundance is based on Callewaert and Michiels2, Berndt et al.32 and this study. As only one GH22i lysozyme has been reported for poriferans33, the respective circle is dotted.
