GENETIC INFORMATION

NOTE
Since the name aphanizophyll can not specify the sugar moiety and the identification of the sugar moiety is unfeasible in many cyanobacteria, the following naming convention is proposed by (Ref. 1222) and S. Liaaen-Jensen: when the sugar moiety is unknown, the name is 4-hydroxymyxol 2'-glycoside, when known, as in the case of rhamnose, it should be named 4-hydroxymyxol 2'-rhamnoside.
