In quiescent cells, proteins with EF-hands are in an apoprotein form; when [Ca 2+] cyt increases they bind Ca 2+and change their conformation.
Less strong Lewis bases are the charge-compensated Glu in an ion-pair with Arg, the amide group of Gln and Asn, and finally the carbonyl of the peptide backbone as the weakest [ 29 ] . The importance of the ligand was demonstrated by substitution of His with the weaker Lewis base Asn in the apoprotein of the bacterial light-harvesting complex LH1, which eliminated assembly of the complex in vivo and reconstitution in vitro [ 30 ] . Formation of a stable coordination bond with a weaker Lewis base is expected to require a stronger Lewis acid.
Lhcb6, a minor LHCP, contains Gly instead of Pro at the position analogous to 82 in Lhcb1, thus eliminating the peptide bond carbonyl of Gly as a ligand, but Lhcb6 has a potential ligand for Chl b in Gln83 [ 39 40 ] . These two LHCP sub-species, along with Lhca4 are most affected by the lack of Chl b in vivo [ 5 ] . Lhcb4 (apoprotein of CP29) has Val instead of Pro at 'position 82', and the absence of site a 6 in Lhcb4 may contribute to its drastic reduction in Chl b -less mutants [ 5 8 ] . However, Lhcb2, Lhcb3, Lhca1, Lhca2 and Lhca3 contain the Gly peptide carbonyl as a ligand (each has Pro at 'position 82' [ 40 ] ) but are reduced only slightly, if any, in amount by the lack of Chl b.
