“At concentrations below 0.8 μg/ml, nystatin inhibits glycine or arginine uptake.”
“ Nystatin , an antifungal antibiotic, inhibits the accumulation, by yeast cells, of glycine , leucine, arginine, and alanine at concentrations that have no effect on the respiration of the cells.”
“The uptake of glycine by yeast cells that have been preincubated with nystatin and then suspended in a nystatin-free medium is much lower than that of normal cells.”
