Fig. 6: Chlorophyll clusters in the stromal and lumenal layers of the Lhcp trimer.

Chlorophyll (Chl) molecules in the stromal Chl layer (a) and lumenal Chl layer (b) of the Lhcp trimer are shown, viewed from the stromal and lumenal sides, respectively. Only the chlorin macrocycles are displayed. Mg–Mg distances between Chl molecules in asymmetric regions of the trimer are indicated with bold numbers.
