Ultrafast exciton energy transfer dynamics in the cryptophyte light-harvesting antenna phycoerythrin 566.

ABSTRACT:

Introduction

Cryptophytes obtain energy through photosynthetic pigments and transfer it to the photosynthetic center on an ultrafast timescale. The mechanisms of such ultrafast excitation energy transfer (EET) in light-trapping complexes are a major focus of algal research. The closed-form phycoerythrin 566 (PE566) binds chemically distinct chromophores, exhibiting spectral properties that differ from those of other closed-form phycobiliproteins in cryptophytes. Elucidating the ultrafast energy transfer pathway of PE566 may provide a deeper understanding of the mechanisms involved in the initial stages of photosynthesis.

Method

We present a comprehensive description of the ultrafast energy transfer kinetics of PE566 under physiological conditions. A combined approach using u
