说明

一般描述

化学结构：肽
Valinomycin is a cyclic peptide, which contains d-valine, d-α-hydroxyvaleric acid, l-valine, and l-lactic acid in the sequential order of cyclo-[(l-Val-d-Hyv-d-Val-l-Lac)3].
 

应用

Valinomycin has been used:
  • to equilibrate intracellular pH and extracellular pH of 5 (and 6-)-carboxyfluorescein succinimidyl ester (cFSE) in Escherichia coli strain B23
  • as an ionophore to equilibrate intracellular pH and extracellular pH of lactic acid bacteria (LAB) strains
  • to establish the desired pH for acid-base transition and formation of K+-valinomycin diffusion potential

生化/生理作用

K+选择性离子载体环羧酚酸肽；钾离子载体，其可解偶联氧化磷酸化、诱导鼠胸腺细胞凋亡、抑制NGF诱导的神经元分化、并拮抗ET诱导的血管收缩。
Valinomycin selectively transfers alkali metal ions via biological and synthetic membranes. The formation of a metal ion-peptide complex contributes to this ion-transporting. Valinomycin can create stable complexes with potassium, rubidium, and cesium (K+, Rb+, and Cs+) .
