Gibberellin biosynthesis in bacteria: separate ent-copalyl diphosphate and ent-kaurene synthases in Bradyrhizobium japonicum.

abstract：:We developed a novel method to quantitatively measure GTP gamma S binding to specific G proteins in crude membranes using G-protein antibodies. The basic strategy was that the materials were initially incubated with [35S]GTP gamma S at 37 degrees C. After 4 degrees C incubation in the wells of an ELISA plate precoated...
