Br. Green et W. Kuhlbrandt, SEQUENCE CONSERVATION OF LIGHT-HARVESTING AND STRESS-RESPONSE PROTEINS IN RELATION TO THE 3-DIMENSIONAL MOLECULAR-STRUCTURE OF LHCII, Photosynthesis research, 44(1-2), 1995, pp. 139-148
The structure of pea light-harvesting complex LHCII determined to 3.4
Angstrom resolution by electron crystallography (Kuhlbrandt, Wang and
Fujiyoshi (1994) Nature 367: 614-621) was examined to determine the re
lationship between structural elements and sequence motifs conserved i
n the extended family of light-harvesting antennas (Chl a/b, fucoxanth
in Chl a/c proteins) and membrane-intrinsic stress-induced proteins (E
LIPs) to which LHCII belongs. It is predicted that the eukaryotic ELIP
s can bind at least four molecules of Chi. The one-helix prokaryotic F
LIP of Synechococcus was modelled as a homodimer based on the high deg
ree of conservation of residues involved in the interactions of the fi
rst (B) and third (A) helices of LHCII.
