Lysozyme mode of action

WebMechanism of action. Erythropoietin or exogenous epoetin alfa binds to the erythropoietin receptor (EPO-R) and activates intracellular signal transduction pathways 3. The affinity (Kd) of EPO for its receptor on human cells is ∼100 to 200 pM 4. Upon binding to EPO-R on the surface of erythroid progenitor cells, a conformational change is ... WebThe bactericidal properties of lysozyme are primarily ascribed to its N-acetylmuramoylhydrolase enzymic activity, resulting in peptidoglycan hydrolysis and cell lysis. However, an increasing body of evidence supports the existence of a nonenzymic and/or nonlytic mode of action.
