 Title    Binding o f Antibodies onto the Thylakoid Membrane VII. Localization o f Coupling Factor o f Photophosphorylation in the Lamellar System o f Chloroplasts from Antirrhinum majus  
 Abstract    The maximal binding o f antibodies against the subunits o f the coupling factor o f photo­ phosphorylation onto the ultrasonic sediment and to stroma-freed chloroplasts o f Antirrhinum majus was determined. Different surfaces o f the thylakoid membrane are accessible to antibodies in both chloroplast preparations. Stroma-freed chloroplasts bind antibodies only at the outer sur­ face, which is directed towards the stroma in intact chloroplasts. In the ultrasonic sediment, which is the product of ultrasonication and centrifugation, as was demonstrated by electronmicroscopy, the major part o f the surface directed towards the inside o f the thylakoids is accessible. Both chloroplasts preparations are able to bind different amounts o f antibodies to the five sub­ units of the coupling factor. While antigenic determinants o f all five subunits are present on the surface directed to the outside, the «^-components seems to be lacking on the surface directed
