It should be noted, however, that several LHCPs accumulate in chloroplasts in the absence of Chl b [ 5 8 ] , perhaps because they integrate more easily into membranes, which implies that other features of the proteins are involved.
This result, obtained with cells incubated at 25°C, was consistent with localization of LHCPs on envelope membranes in cells immediately after initiation of thylakoid biogenesis at 38°C [ 16 ] . At the higher temperature, not all the newly synthesized LHCPs were incorporated into envelope membranes, and the excess accumulated in cytosolic vacuoles [ 16 17 ] . This evidence for the envelope as the site of initial interaction of LHCPs with Chl was also supported by proliferation of envelope-derived vesicles in dark-grown Chlamydomonas cells exposed to only a few minutes of light [ 18 ] and the lack of thylakoids in a mutant of Arabidopsis deficient in a protein apparently required for formation of vesicles from the inner membrane of the envelope [ 19 ] .
A stable complex should be achieved with only Chl a, in a Chl b -less plant or by in vitro reconstitution, when weak ligands in LHCPs are replaced with stronger Lewis bases.
Several groups developed a more direct approach for determining occupancy by analyzing effects on the composition of the final complex, after in vitro reconstitution, when amino acid residues in LHCPs were replaced with substitutes that are unable to serve as a ligand.
The work already done has established that several LHCPs are imported into the chloroplast at a substantial rate only when sufficient Chl b is available and they accumulate initially in the envelope membrane.
