[Abstract] Histone deacetylases (HDACs) catalyzing the removal of acetyl groups from lysine residues of histone and non-histone proteins play vital roles in regulation of gene transcription. In plants, HDACs can be grouped into three families, including RPD3-type, SIR2-type and plant specific HD2-type HDACs. Here we describe a method to determine plant HDAC enzymatic activity. This protocol includes expression, purification and enzymatic activity assay of recombinant plant HDACs expressed in Escherichia coli (E. coli) and Arabidopsis thaliana (A. thaliana).
[摘要] 组蛋白脱乙酰酶（HDAC）催化从组蛋白和非组蛋白蛋白的赖氨酸残基去除乙酰基在调节基因转录中起重要作用。 在植物中，HDAC可以分为三个家族，包括RPD3型，SIR2型和植物特异性HD2型HDAC。 在这里我们描述了一种确定植物HDAC酶活性的方法。 该方案包括在大肠杆菌（大肠杆菌）和拟南芥（）中表达的重组植物HDAC的表达，纯化和酶活性测定 >拟南芥）。
