| pertussis toxin |
<protein> Protein complex (ca 117 kD). An A B toxin, the active subunit is a single polypeptide 28 kD), the binding subunit a pentamer (two heterodimers, 23 + 11.7 kD, 11.7 + 22 kD and a monomer (9.3 kD) that binds the heterodimers). The active subunit ADP ribosylates the _ subunit of the inhibitory GTP-binding protein (Gi). Crucial to the pathogenicity of Bordetella pertussis, the causative agent of whooping cough.

| cholera toxin |
<protein> A multimeric protein toxin from Cholera vibrio. The toxic A subunit activates adenyl cyclase irreversibly by ADP ribosylation of a Gs protein. The B subunit facilitates passage of the A subunit across the cell membrane.

<chemical> Conjugate of horseradish peroxidase and cholera toxin
Synonym: bhrp, horseradish peroxidase-cholera toxin b subunit, cholera toxin-horseradish peroxidase, horseradish peroxidase-cholera toxin, ib4-hrp

| scarlet fever erythrogenic toxin |
A culture filtrate of lysogenised group A strains of beta-haemolytic streptococci, erythrogenic when inoculated into the skin of susceptible persons, and neutralised by antibodies that appear during scarlet fever convalescence; three immunological types (A, B, and C) are recognised.
Synonym: Dick test toxin, erythrogenic toxin, scarlet fever erythrogenic toxin.

Corynebacterium diphtheriae toxin diluted so that the inoculated dose (0.1 or 0.2 ml) will contain 1/50 th of guinea pig minimal lethal dose.
See: Schick test.
Synonym: diagnostic diphtheria toxin.
(05 Mar 2000) |

Examples: Shiga toxin, Shiga like toxins SLT 1 and SLT 2 of Escherichia coli.
(18 Nov 1997) |
| Shiga toxin |
