FIG 7 .
Absence of MurI homologues is prevalent in microbes of the PVC group superphylum. Shown is a list of representative species comprising the PVC group superphylum. Species possessing homologues of the DAP epimerase encoded by P. acanthamoebae (DapFPA) but lacking homologues of the glutamate racemase (MurIPA) are black. Species lacking both DapFPA and MurIPA homologues are blue. Species encoding homologues of both DapFPA and MurIPA are red. More comprehensive lists of PVC group members arranged by DAP epimerase/glutamate racemase status are provided in Tables S3 and S4.
