Lhcb4 — Pisum sativum

Summary

PSAT5G126240 (Lhcb4) in garden pea encodes a chlorophyll a-b binding protein, a component of the light-harvesting complex. The gene is associated with photosynthesis, specifically light harvesting in both photosystem I and photosystem II, and is localized to the thylakoid membrane. It has been connected to the xanthophyll cycle, photoprotection, chlorophyll fluorescence, and response to light stimulus. The encoded protein also binds metals. Studies of related genes in other species link the Lhcb4 family to these photosynthetic and photoprotective processes.
