Amino acid analysis of Saccharomyces cerevisiae cells indicated that neutral amino acids such as glycine and alanine were probably excluded from the vacuoles, and that vacuolar H(+)-ATPase (V-ATPase) was involved in the vacuolar compartmentalization of these amino acids. We found that vacuolar membrane vesicles export neutral amino acids in an ATP-dependent manner. This is important in identifying vacuolar transporters for neutral amino acids.
对酿酒酵母细胞的氨基酸分析表明，甘氨酸和丙氨酸等中性氨基酸可能被排除在液泡之外，并且液泡H(+)-ATP酶（V-ATP酶）参与了这些氨基酸的液泡区室化。我们发现液泡膜囊泡以ATP依赖的方式输出中性氨基酸。这对于鉴定中性氨基酸的液泡转运体很重要。
