Protein PSII-G. An additional component of photosystem II identified through its plastid gene in maize.
An unidentified open reading frame, 248 or 255 amino acids in length, on the maize chloroplast DNA fragment Bam5 was sequenced. It encodes a protein which contains a high proportion of hydrophilic amino acids, of which 22% are hydroxylated, interrupted by hydrophobic domains. A synthetic peptide corresponding to a hydrophilic sequence was used to generate antibodies. Western blots of photosystem I and II complexes prepared from maize and spinach thylakoids indicate that the psbG gene product is a membrane-associated protein of the photosystem II complex that migrates as a 24-kDa species on polyacrylamide gel electrophoresis.
