PAP2 — Brassica oleracea var. botrytis

Summary

BoPAP2 (PAP2) on cauliflower chromosome 4 encodes a protein with a predicted alpha/beta hydrolase fold and a peptidase S33 domain, placing it in the serine protease/carboxylesterase family. The gene is annotated to pigmentation, anthocyanin metabolism and anabolism, and proteolysis, and its product localises to the vacuole and cytosol. BoPAP2 is associated with leaf senescence and anthocyanin accumulation. Related genes in other species link the family to anthocyanin biosynthesis, and sequence-similarity evidence connects the family to flower and petal colour, anthocyanin content, leaf senescence and photochemical quenching.
