Evidence of signal amplification in the signal transduction pathway. Introduction: Different genes of a cell get activated in different circumstances. Bacterial cells like Escherichia coli express a high amount of OmpC in hypertonic solutions as compared to isotonic or hypotonic solutions. Other proteins, such as membrane protein (EnvZ), act as a protein kinase and get phosphorylated. They also phosphorylate proteins like OmpR (cytoplasm protein). The amount of EnvZ and OmpR after incubation with 32 P-radiolabeled ATP is recorded in the following table: Table A An isotonic solution consisting of nutrient broth only A hypertonic solution consisting of Nutrient broth and 20% sucrose solution EnvZ 63 113 OmpR 2043 3525
