PHAGOCYTOSIS INHIBITION AND REVERSAL. I. EFFECT OF GLYCOLYTIC INTERMEDIATES AND NUCLEOTIDES ON PARTICLE UPTAKE.

abstract：:Beta toxin is a neutral sphingomyelinase secreted by certain strains of Staphylococcus aureus. This virulence factor lyses erythrocytes in order to evade the host immune system as well as scavenge nutrients. The structure of beta toxin was determined at 2.4-A resolution using crystals that were merohedrally twinned. T...
