2.3.1.24 | fumonisin B1 | reversible competitive inhibition, inhibits ceramide synthase in mouse brain microsomes with a competitive-like kinetic behavior with respect to both sphinganine and stearoyl-CoA. Fumonisin B1 inhibits ceramide synthase activity when palmitoyl-CoA, stearoyl-CoA, or lignoceroyl-CoA are used as the co-substrate, cf. EC 2.3.1.297 and 2.3.1.24 | Mus musculus | |
2.3.1.24 | additional information | fumonisins block sphingosine biosynthesis by inhibiting the conversion of sphinganine to dihydroceramides, which precedes introduction of the 4,5-trans-double bond of sphingosine. Fumonisins, mycotoxins produced by Fusarium moniliforme and a number of other fungi, cause neuronal degeneration, liver and renal toxicity, cancer, and other injury to animals. Fumonisin Bl inhibits complex sphirqolipid synthesis from galactose and sphinganine, effects on the amounts of free sphingosine and sphinganine and on total complex sphingolipids, overview | Mus musculus | |
2.3.1.297 | fumonisin B1 | reversible competitive inhibition, inhibits ceramide synthase in mouse brain microsomes with a competitive-like kinetic behavior with respect to both sphinganine and stearoyl-CoA. Fumonisin B1 inhibits ceramide synthase activity when palmitoyl-CoA, stearoyl-CoA, or lignoceroyl-CoA are used as the co-substrate, cf. EC 2.3.1.297 and 2.3.1.24 | Mus musculus | |
