FTSH — Capsicum annuum

Summary

CaFTSH (T459_13473) on pepper chromosome 4 encodes an ATP-dependent zinc metalloprotease FTSH, chloroplastic, belonging to the FtsH peptidase M41 family. The enzyme exhibits ATP-dependent peptidase, metalloendopeptidase, and ATP hydrolase activities, binds ATP, metals, zinc, and mRNA, and localizes to the chloroplast thylakoid membrane, chloroplast membrane, and mitochondria. CaFTSH is associated with photosynthesis light reaction, PSII-associated light-harvesting complex II catabolic process, chlorophyll breakdown, fruit ripening, cytoplasmic male sterility, heterosis, fruit weight, pungency, stomatal resistance, and chlorophyll content. Studies of related genes in other species link the family to metalloprotease activity.
