Abstract
In the previous presentation, we suggested the potential substrate related to wall proteins for the tobacco purple acid phosphatase (NtPAP12). In order to examine whether they are really physiological substrates in the tobacco cells, those enzyme activities in the transgenic cells overexpressing NtPAP12 were compared to those in the wild-type cells. Those activities in some wall enzymes were enhanced in the transgenic cells, on the other hand, some wall enzymes were suppressed in the transgenic cells. In this presentation, we would suppose a possible dephosphorylation-action of a wall enzyme by the purple acid phosphatase, which related to the phenotype in the transgenic cells.
