PSI — Capsicum annuum

Summary

CaPSI (T459_02536) on pepper chromosome 1 encodes a chlorophyll-binding protein of the photosystem II antenna-like superfamily. The gene is annotated to photosynthetic electron transport in photosystem II, nonphotochemical quenching, and the photosynthetic electron transport chain, and its product localises to photosystem II, the thylakoid, and the chloroplast thylakoid membrane. CaPSI is also associated with digestion and homeostasis, as well as with glucose content and photochemical quenching. Studies of related genes in other species link the family to the photosystem II CP47 reaction center protein and to rubisco and protein content.
