概要

• 論文の詳細を見る

• IAA biosynthesis in Alaska peas is shown to be plastid localized. D-tryptophan is a much better substrate than is L-tryptophan, and IAA production is dependent on a keto acid. In line with this, a plastid localized D-tryptophan aminotransferase has been found and purified 1,500 fold. The enzyme has no activity with L-tryptophan and prefers pyruvic or oxaloacetic acid as an amino group acceptor. Activities are much higher in dark than in light grown tissues. Some possible physiological ramifications are discussed.
