AS1 — Medicago truncatula

Summary

MTR_2G013010 (AS1) on chromosome 2 of barrel medic encodes a polyphenol oxidase with a tyrosinase-like domain and copper-binding sites, exhibiting aureusidin synthase activity and catecholase activity. The gene is associated with proanthocyanidin and anthocyanin anabolism, pigment anabolism, pigmentation, secondary metabolism, leaf morphogenesis, and nodulation. It has been linked to seed coat color, amino acid content, and protein content. The encoded protein localizes to the vacuolar lumen and chloroplast thylakoid lumen. Studies of related genes in other species connect the family to tyrosinase copper-binding domain-containing proteins and EC numbers 1.21.3.6, 1.14.99.47, and 1.10.3.1.
