Histone deacetylase 5 - Wikipedia
Histone deacetylase 5 is an enzyme that in humans is encoded by the HDAC5 gene. [5][6][7] Histones play a critical role in transcriptional regulation, cell cycle progression, and developmental events. Histone acetylation/deacetylation alters chromosome structure and affects transcription factor access to DNA.

一文带你了解组蛋白去乙酰化酶(HDAC) - 知乎专栏
HDAC8和HDAC11则优先水解非乙酰酰基赖氨酸底物,HDAC10则是一种多胺去乙酰化酶。 乙酰赖氨酸底物位于一个由疏水残基围绕的狭窄通道中,其中酪氨酸残基通过构象翻转与羰基氧形成氢键(图A)。 通道的疏水特性以及酪氨酸残基的构象变化赋予了酶对乙酰赖氨酸侧链的特异性。 通道末端存在一个由天冬氨酸和组氨酸残基配位的锌离子,与一个通过电荷中继机制被激活的水分子结合。 水分子对羰基的亲核攻击生成四面体氧阴离子中间体(图B),随后该中间体坍缩,生 …

HDAC5, a Key Component in Temporal Regulation of p53 …
2013年11月7日 · K120 acetylation is a modification critical for recruitment of p53 to proapoptotic targets. Our data reveal that histone deacetylase 5 (HDAC5) binds to p53 and abrogates K120 acetylation, resulting in preferential recruitment of p53 to proarrest and antioxidant targets at early phases of stress.
