Putting it together: CEPA1 functions as a Photosystem I assembly factor
The Plant Cell: In a NutshellBackground:
Photosystem I (PSI) is a large pigment-protein complex that participates in photosynthetic electron transfer. While its structure is well resolved, its assembly pathway is less clear. A set of proteins mediating the step-wise assembly of PSI subunits, known as PSI assembly factors, has…
