aSee notes for Table 1 for a general description of column entries.
bThe sequence Z99832 (Cryptoglena pigra) is not shown in the table. Its 102 amino acids are homologous to the C-terminus of other euglenoid psbCI4 intron-encoded proteins but the DNA sequence encoding the N-terminus was not reported.
cAccession number is for the protein database entry. The DNA sequence was reported by Kück (49).
dThe published size is 274 amino acids; three frameshifts add 204 amino acids with similarity to group II intron-encoded proteins (8).
eTranslation of the DNA database entry was reported by Doetsch et al. (50).
