The effects of single L-amino acid substitutions on the lethal potencies of the microcystins.

R D Stoner1, W H Adams, D N Slatkin, H W Siegelman.   

Abstract

Microcystin-LR and -LA are more toxic than microcystin-LY and -RR in adult mice. They induce different degrees of thrombocytopenia and leukopenia, and the lethalities of their binary and ternary mixtures are addictive. Postnatal mice are resistant to doses of microcystin-LR that are lethal to adults but they are susceptible to higher doses. Substitution of a single L-amino acid for another in a microcystin markedly affects the dosimetric potency, but not the pathophysiology of its toxicity.
