From: Signature proteins for the major clades of Cyanobacteria
Partial sequence alignment of the protein protochlorophyllide oxidoreductase showing a 1 aa deletion that is commonly shared by all Prochlorococcus strains except MIT 9303 and MIT 9313. This indel provides evidence for the deep branching of these Prochlorococcus strains relative to all other strains.
