Abstract

alpha-Aminoisobutyric acid is actively accumulated by the epithelium of the cornea of the toad, Bufo marinus, resulting in a tissue to medium ratio of 4 to 1 after 40 min of incubation. The accumulation of alpha-aminoisobutyric acid is ouabain-sensitive and dependent upon the presence of extracellular sodium. Transport is inhibited by carbon monoxide, 6-aminonicotinamide, arsenite and n-heptyl-3-hydroxy-quinoline-n-oxide and stimulated by diamide.

摘要

α-氨基异丁酸被海蟾蜍(Bufo marinus)角膜上皮细胞主动积累,孵育40分钟后组织与培养基的比例达到4比1。α-氨基异丁酸的积累对哇巴因敏感,且依赖于细胞外钠的存在。一氧化碳、6-氨基烟酰胺、亚砷酸盐和正庚基-3-羟基喹啉-N-氧化物可抑制其转运,而二酰胺可刺激其转运。
