General Information | Comment | Organism |
---|---|---|
malfunction | bacteria lacking PPX exhibit increased resistance to complement-mediated killing. Loss of PPX leads to decrease in alternative pathway activation on bacterial surface | Neisseria meningitidis |
physiological function | the biochemical activity of PPX is necessary for interactions with the complement | Neisseria meningitidis |
