abstract：:We examined the substrate specificity of two mutated geranylgeranyl diphosphate synthases, I-9 and I-11, with respect to several artificial substrates. These mutated enzymes have replacements in the amino acid sequences from positions 170 to 173, which are thought to be a part of the putative substrate binding region....
