EC Number Cloned (Comment) Organism
3.1.3.11 fbp-II gene from Synechococcus PCC7942 is introduced into Nicotiana tabacum cv. xanthi nuclear DNA using a fusion construct with the tomato rbcS promoter and transit peptide. The FBPase-II protein is localized in the chloroplasts of six. Protein levels of FBPase-II in the transgenic plants are decreased to 40% under dark conditions compared with those under light conditions Synechococcus elongatus PCC 7942 = FACHB-805
