| Popis: |
A homogenate of guinea pig polymorphonuclear leucocytes contains an enzyme system capable of oxidizing, in presence of oxygen, NADPH and NADH with the formation of hydrogen peroxide. The enzyme is much more active towards NADPH than to NADH. The presence of manganese ions strongly enhances the oxidase activity. It is suggested that the release of the NADPH oxidase in the leucocytes, during phagocytosis, accounts for the stimulation of the hexose monophosphate pathway that occurs in phagocytosis. |
