The PufX quinone channel enables the light-harvesting 1 antenna to bind more carotenoids for light collection and photoprotection.

FEBS letters - 1 Feb 2017

Olsen John D, Martin Elizabeth C, Hunter C Neil

Abstract excerpt

Photosynthesis in some phototrophic bacteria requires the PufX component of the reaction centre-light-harvesting 1-PufX (RC-LH1-PufX) complex, which creates a pore for quinone/quinol (Q/QH2 ) exchange across the LH1 barrier surrounding the RC. However, photosynthetic bacteria such as Thermochromatium (T.) tepidum do not require PufX because there are fewer carotenoid binding sites, which creates multiple pores in...
