Fumonisin B1, a fungal mycotoxin that grows on corn and other agricultural products, alters sphingolipid metabolism by inhibiting ceramide synthase. The precise mechanism of fumonisin B1 toxicity has not been completely elucidated; however, a central

The magnetization-inversion-transfer NMR technique has been used to determine the activation enthalpy (delta H not equal to) for the transport of the 7Li+, 23Na+, and 39K+ ions through the gramicidin channel incorporated into vesicle membranes. The a

Gramicidin is a 15 amino acid linear polypeptide which forms cation conducting channels in lipid membranes (Meyers and Haydon, 1972; Anderson, 1983). The gramicidin channel in a lipid bilayer membrane is shown in Figure 1. The amino acid sequence of
