Figure 2From: An extended phylogenetic analysis reveals ancient origin of "non-green" phosphoribulokinase genes from two lineages of "green" secondary photosynthetic eukaryotes: Euglenophyta and ChlorarachniophytaTaxon-specific gaps in alignment of phosphoribulokinase amino acid sequences from 56 operational taxonomic units (Figure 1) plus 4 dinoflagellates. Numbers at the top represent amino acid positions of the Chlamydomonas reinhardtii PRK protein (AAA33090).Back to article page
