1. Suplemental Data Figure S1. Alignment of deduced amino acid sequence of CaGA2ox1 and other GA2ox homologs from the pepper EST database. Dark shading indicates amino acid residues that are conserved in CaGA2ox1. The asterisks indicate amino acid residues presumed to bind Fe at the active site. The closed triangles show the putative 2-oxoglutarate binding site.
