Abstract

The psaI gene encoding the 5.2 kDa protein component (PsaI) of the photosystem I complex was cloned from the cyanobacterium Anabaena 29413. The gene is present in single copy in this cyanobacterial genome. The nucleotide sequence of a 500 bp region of the cloned DNA revealed the presence of an open reading frame encoding a 46 amino acid long polypeptide. The N-terminal 11 residues are absent in the mature polypeptide and thus represents the first identified cleavable presequence on the PsaI protein. We suggest that this presequence directs the N-terminus of the protein to the thylakoid lumen.
