Dose-dependent GAPDH activity was detected in whole bacterial cells from exponentially growing cultures, indicating that an active form of GAPDH is located outside the plasma membrane. This activity represents roughly 10-20% of total cell activity, and it is not reduced by pretreatment of the cells with trypsin.
