Exposed portions of the 32 kd chloroplast membrane quinone-binding and triazine herbicide-binding protein of photosystem II have been mapped to the lumenal or to the outer (stromal) surface of the thylakoid by following reactions of antibodies generated against synthetic peptides corresponding to predicted hydrophilic amino acid sequences with normally oriented or everted membrane vesicles. These data have led to the construction of a model with
five membrane-spanning domains
. The model has been verified, in part, by immunoblots of fragments of the protein produced by
trypsin
treatment of thylakoids with peptide-specific antibodies. Some of the hydrophilic loops appear to be in close contact with proteins of the oxygen evolving complex of photosystem II inasmuch as their removal increases the antibody reaction.
