Taurine transport in isolated brush-border-membrane vesicles from rat kidney is concentrative and it is driven by the Na+ gradient and transmembrane potential difference; binding is not a significant component of net uptake. The Na+-dependent component of net uptake is saturable with an apparent Km of 17 microM. The taurine-transport mechanism is selective for beta-amino compounds.
从大鼠肾脏分离的刷状缘膜囊泡中的牛磺酸转运是浓缩性的,由Na+梯度和跨膜电位差驱动;结合不是净摄取的重要组成部分。净摄取的Na+依赖性成分是可饱和的,表观Km为17 microM。牛磺酸转运机制对β-氨基化合物具有选择性。
