Gibberellin 2-Oxidases from Seedlings of Adzuki Bean (Vigna angularis) Show High Gibberellin-Binding Activity in the Presence of 2-Oxoglutarate and Co2+
@article{Park2005Gibberellin2F, title={Gibberellin 2-Oxidases from Seedlings of Adzuki Bean (Vigna angularis) Show High Gibberellin-Binding Activity in the Presence of 2-Oxoglutarate and Co2+}, author={Seung-Hyun Park and Masatoshi Nakajima and Masayuki Sakane and Zhengjun Xu and Katsushi Tomioka and Isomaro Yamaguchi}, journal={Bioscience, Biotechnology, and Biochemistry}, year={2005}, volume={69}, pages={1498 - 1507} }
Five full-length cDNA encoding gibberellin 2-oxidases, VaGA2oxA1, VaGA2oxA2, VaGA2oxB1, VaGA2oxB2, and VaGA2oxB3, were cloned from etiolated adzuki bean (Vigna angularis cv. Dainagon) seedlings, and their enzymatic characteristics were examined using recombinant enzymes fused with glutathione S-transferase (GST). Recombinant VaGA2oxA1 (rVaGA2oxA1) and rVaGA2oxA2 showed 2β-hydroxylation activity by converting GA1, GA4, GA9, GA20, GA4-methyl ester, and 16,17-dihydro-GA4 to the corresponding 2…
