Figure 5From: Evidence that the intra-amoebal Legionella drancourtii acquired a sterol reductase gene from eukaryotesEukaryotic sterol biosynthesis. Ergosterol and cholesterol are synthesized in fungi and all eukaryotes respectively. Enzymes present in L. drancourtii (L), C. burnetii (C) and Candidatus "P. amoebophila" (P) are represented in italics and enzymes present in the previous phylogenetic tree are framed.Back to article page
