On the Toxin Production of the Diphtheria Bacillus [PDF]

open access: yesEpidemiology and Infection, 1912
Everyone who has been occupied with the weekly production of diphtheria toxin in quantity has been struck with the great variations which may and usually do occur in the strength of the toxin from week to week. It is indeed extraordinary as Madsen remarks (1908, p.

Diphtheria toxin-based efficient target-switchable anticancer drug

open access: yes, 2018
Recombinant immunotoxins (RITs) have been extensively utilized in the field of targeted cancer therapy. RITs are composed of toxins derived from natural bacterial strains and antibodies for target specific killing of cancer cells.

proHB-EGF를 발현하는 형이전환 쥐를 만들어 Diphtheria toxin의 동물실험

open access: yes, 2003
Whereas diphtheria and the mechanism of action of diphtheria toxin, the bacterial molecule that induces the disease, have been studied and understood for some time, the receptor that allows animal cells to bind the toxin escaped identification until ...

Proteolytic activity of diphtheria toxin

open access: yes, 2005
Purified samples of diphtheria toxin spitted human fibrinogen, human serum albumin and gelatin. Splitting was completely inhibited by nitrotetrazolium blue (0.01 mol) but no other active oxygen species.

Diphtheria toxin and its mutant crm 197 differ in their interaction with lipids

open access: yes, 1987
The interaction of diphtheria toxin and its enzymatically deficient mutants crm 176 and crm 197 with liposomes has been studied by turbidity measurement and hydrophobic photolabelling with photoactivatable phosphatidylcholines.

Identification of Formaldehyde-Induced Modifications in Diphtheria Toxin

open access: yes, 2020
Diphtheria toxoid is produced by detoxification of diphtheria toxin with formaldehyde. This study was performed to elucidate the chemical nature and location of formaldehyde-induced modifications in diphtheria toxoid.

Optimization of diphtheria toxin production by Corynebacterium diphtheriae using a casein-based medium in a fermenter

open access: yes, 2016
The Td-based combined vaccine contains only small amounts of the diphtheria toxoid antigen. However, a high level of purity is necessary for this antigen.

Inactivation of diphtheria toxin by site-directed mutagenesis

open access: yes
Diphtheria toxin is a single polypeptide chain produced by toxigenic strains of Corynebacterium diphtheriae that causes the disease diphtheria in humans by gaining entry into the cytoplasm of cells and inhibiting protein synthesis.

HISTIDINE-21 IS INVOLVED IN DIPHTHERIA-TOXIN NAD+ BINDING

open access: yes, 1990
Histidine-21 is the sole histidine present in the A chain of diphtheria toxin and recent evidence suggests that it is involved in NAD+ binding. Fluorimetric assays of NAD+ binding and diethylpyrocarbonate modification performed at different pH values ...

Topology of diphtheria toxin B fragment inserted in lipid vesicles

open access: yes, 1994
Diphtheria toxin (DT) is a bacterial protein that crosses the membrane of endosomes of target cells in response to the low endosomal pH. In this paper, we have inserted diphtheria toxin in asolectin vesicles at pH 5.0 and treated the reconstituted system
