Abstract

The small polypeptides present in the pea photosystem II reaction centre complex have been separated by high-resolution SDS-polyacrylamide gel electrophoresis and characterised by N-terminal amino acid sequencing. Two polypeptides are identified as the α- and β-subunits of cytochrome b559 which are the products of the pdbE and psbF genes. A third polypeptide, of 4.5 kDA, is identified as the product of a small open reading frame in chloroplast DNA. The gene for this polypeptide, psbI, is located just downstream of the psbK gene chloroplast DNA.
