Amino acid sequence of the ribulose-1,5-bisphosphate carboxylase/oxygenase small subunit from Euglena

Abstract: The amino acid sequence of the ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) small subunit (SSU) from Euglena has been established by alignment of the sequence of peptides obtained by cleavage with chymotrypsin, trypsin, Staphylococcus aureus protease or formic acid. The Euglena SSU has 138 amino acids and thus represents longest SSU sequence described so far. Homology is only 41% with cyanobacteria SSU and about 51% with higher plant SSU, whereas it is around 75% between higher plants. The largest… Show more

“…When compared to the Fucus small subunit, however, 83 ~o similarity is observed. The similarity between land plant small subunits is usually greater than 70~o [18]. The Fucus sequence is much more closely related to that from Cryptomonas 4) than to those from any of the other organisms in the comparison.…”

“…Indeed, the E. gracilis psaA sequence appears to be no more homologous to the higher plant psaA sequences than to the cyanobacterial psaA sequence. The distinctive phylogenetic position of E. gracilis has been noted before in sequence comparisons of psaA [31], rbcL [19], and rbcS [52] gene products. The E. gracilis psaA gene does differ from all other psaA genes sequenced to date in having three introns [11].…”

“…In addition, the derived amino acid sequence of Olisthodiscus (Boczar et al 1989) and Cryptomonas (Douglas and Durnford 1989) Chromophytic and rhodophytic SS polypeptides show minimal similarity (20-40% identity) to chlorophytic plant and blue-green algal proteins (Boczar et al 1989). In contrast, land plant, green algal (Sailland et al 1986, Simard et al 1988) and blue-green algal Rubisco SS amino acid sequences are 40-78% similar (Miziorko and Lorimer 1983), although homologies are greater among organisms within a group than between groups (Simard et al 1988). Thus, chromophytic and rhodophytic SS polypeptides are more similar to each other (and to Alcaligenes) than they are to the cyanobacterial or chlorophytic plant Rubisco small subunits.…”
