histones are proteins that regulate dna packing, and histone deacetylases are enzymes that control the way those proteins work.
组蛋白控制dna折叠,而组蛋白去乙酰酶抑制剂是种控制这些蛋白质工作的酶。
it ensures that the h4 histones have plenty of attached acetyl groups, so the dna wrapped around the histone once again becomes available for transcription.
