In addition, several cofactors, such as chlorophylls, phylloquinones, carotenoids and iron-sulfur clusters are bound by this complex. We now have a detailed understanding of the structural basics, yet we know very little about the molecular details of the assembly process that finally yields functional PS I<span style="font-size:14.0pt; font-family:Arial;mso-fareast-font-family:HiddenHorzOCR;mso-ansi-language:EN-US; mso-fareast-language:EN-US;mso-bidi-language:AR-SA">. Moreover, not much is known about the molecular dynamics of PS I in the thylakoid membrane or its regulated degradation. These areas have become the focus of recent work and first results have emerged. In this minireview we describe the latest findings in this fascinating and rapidly evolving field.</span
