應用

猪心脏来源柠檬酸合酶用于:
  • 注入蝾螈卵子,确定受精时,其在卵子激活中的重要性
  • 制备反应混合物,确定丙酮酸羧化酶活性
  • 检查其是否能够诱导未受精卵中的[Ca22+]增加和卵子激活

生化/生理作用

柠檬酸合成酶催化柠檬酸在辅酶 A 存在下转化为乙酰辅酶 A,释放 H2O和草酰乙酸。该酶分子量为 85 kDa,pI 为 6.1-6.6。可被氟乙酰辅酶 a、棕榈酰辅酶 a 和柠檬酸辅酶 a 抑制。当其被乙酸酐乙酰化或被碘碘化时也受到抑制。

單位定義

一个装置将形成 1.0μ37°C 下 pH 8.0 时每分钟由草酰乙酸和乙酰 CoA 生成的柠檬酸盐摩尔数。

外觀

用 3.2 M(NH4)2SO4 溶液 (pH 7.0) 混悬。

準備報告

溶于水,形成 1 mg/mL 浓度的澄清溶液。

Small Heat Shock Proteins (sHSPs) are a diverse family of molecular chaperones that prevent protein aggregation by binding clients destabilized during cellular stress. Here we probe the architecture and dynamics of complexes formed between an oligomeric sHSP and client by

A recently discovered group of conditionally disordered chaperones share a very unique feature; they need to lose structure to become active as chaperones. This activation mechanism makes these chaperones particularly suited to respond to protein-unfolding stress conditions, such as oxidative
