TABLE 2.

Tentative site energy assignments for Lhca chlorophylls

	Chlorophyll a	Chlorophyll b	Tentative chlorophyll b sites
Lhca1	677.6	646.5	1017, 1026, 1031
Lhca2	678.6	646.9	1017, 1021, 1026, 1031, 1033
Lhca3	676.4	647.3	1031, 1032, 1033
Lhca4	676.2	646.9	1017, 1021, 1026, 1031, 1032, 1033
PSI core avg.	678.8	—	—

Energies are reported in corresponding wavelengths in nm. A uniform site energy value as stated in the table was assigned to all chlorophylls of a given type (a or b) within a given chain (i.e., Lhca1, Lhca2, Lhca3, and Lhca4), including the associated linker chlorophylls, with the exception of four specific chlorophylls; chlorophylls 1015 and 1025 in chains 3 and 4 are assigned a site energy of 695 nm rather than the stated uniform value for the other chlorophyll a units of the same chains. All Lhca chlorophylls are assumed to be chlorophyll a with the exception of the ones denoted in the table to be tentatively assigned to be chlorophyll b (see text). As a point of reference, the average site energy value for PSI core chlorophylls taken from the cyanobacterial model (38) is set to 678.8 nm. The site energy for non-conserved chlorophylls of the PSI core, including the gap chlorophylls, is also set to this uniform value. The values in this table were used for the results in Column C of Table 1.
