Figure 2From: Amino acids biosynthesis and nitrogen assimilation pathways: a great genomic deletion during eukaryotes evolutionLysine anabolic pathways. Schematic representation for presence/absence of enzymes involved in lysine biosynthesis. K(1) represents Fungi α-aminoadipate (AAA) pathway; K(2) bacteria, plants, and algae diaminopimelate (DAP) pathway; K(3) archaea α-aminoadipate (AAA) variant pathway. Taxonomic tree displayed at phyla level. Circles represent detection of complete proteins and triangles detection of complete and fragmented proteins. Colors are as for Figure 1. Saccharomyces cerevisiae (Ascomycota), Arabidopsis thaliana (Streptophyta) and Pyrococcus horikoshii (Euryarchaeota) were used as seeds.Back to article page
