PAP2 — Brassica oleracea

Summary

BoPAP2, encoded by gene BOLC102_C08P025810.1 on cabbage chromosome 8, is a purple acid phosphatase family protein containing PAPs_N, PAPs_C, calcineurin-like and metallo-dependent phosphatase domains. It exhibits phosphoenolpyruvate phosphatase, acid phosphatase, and protein phosphatase activities, binds ferric iron, manganese, cobalt, and zinc, and participates in protein dimerization. The gene is associated with anthocyanin biosynthesis and metabolism, pigmentation, regulation of anthocyanin and ethylene anabolism, mitochondrial RNA modification, mitochondrial outer membrane protein import, regulation of carbohydrate metabolism, and cellular response to phosphate starvation. It localizes to the mitochondrial and chloroplast envelopes, vacuolar lumen, Golgi, endosome, and cell wall. BoPAP2 is linked to photosynthetic rate and anthocyanin content. Related genes in other species connect the family to anthocyanin accumulation, plant growth, and seed oil yield.
