Abstract

In the present work a thorough examination of the oligomeric antenna of P. tricornutum was performed. Solubilisation of thylakoids with n-dodecyl β-d-maltoside in combination with gelfiltration and sucrose density gradient centrifugation revealed the existence of two oligomeric antenna states, the FCPo and FCP complex. Calculation of the molecular masses showed that these complexes are organized as hexamers and trimers, respectively. By MS/MS analysis a specific assignment of the FCPs to their respective genes was achieved. The peripheral antenna contained the majority of the xanthophyll cycle pigments diadinoxanthin and diatoxanthin, while an additional small pool was tightly bound to the photosystem core complexes, indicating the existence of two distinct xanthophyll cycle pigment binding proteins.
