A typical purple bacterial photosynthetic unit consists of two types of light‐harvesting complex (LH1 and LH2) together with a reaction centre. This short review presents a description of the structure of the LH2 complex from Rhodopseudomonas acidophila , which has recently been improved to a resolution of 2.0 Å [Papiz et al., J. Mol. Biol. 326 (2003) 1523–1538]. We show how this structure has helped to reveal the details of the various excitation energy transfer events in which it is involved.
