Pore-forming peptide of pathogenic Entamoeba histolytica.
Open accessAbstract
A polypeptide that causes pore formation in target-cell membranes is implicated in the potent cytolytic activity of pathogenic Entamoeba histolytica. Pore-forming material was purified to apparent homogeneity by a multistep procedure, and its analysis by NaDodSO4/PAGE revealed one peptide of 4-5 kDa under nonreducing or under reducing conditions. Pore-forming activity was measured by depolarization of liposome membrane potential and was found to be optimally expressed at low pH. Active material preferentially inserted into negatively charged lipid vesicles. Treatment of purified amoeba peptide in solution or bound to liposomes with glutaraldehyde revealed oligomers upon NaDodSO4/PAGE, suggesting functionally relevant peptide-peptide interactions. The NH2-terminal amino acid sequence of the amoeba peptide was determined by protein sequencing and revealed a structural similarity to melittin, the membranolytic peptide of bee venom.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
