DESCRIPTION:
Human recombinant BRD4, (residues 1-744), like other human members of the BET family of chromatin-binding proteins (BRD2, BRD3, BRDT), comprises two bromodomains, protein modules that bind e-N-acetyllysine residues. The ubiquitously expressed BRD4 functions as a transcriptional regulator with roles in cell cycle progression and has recently been shown to be an atypical kinase that can phosphorylate RNA Pol II. Recent structural studies have shown that BRD4-1, like the bromodomain-1 of fellow BET family protein BRDT, can bind simultaneously to two acetyllysine residues with appropriate spacing and sequence context, for example a histone H4 peptide acetylated at lysines 5 and 8 (H4K5AcK8Ac). Chromosomal translocations that produce BRD4-NUT fusion proteins are implicated in causation of a rare and aggressive cancer, NUT midline carcinoma. Selective inhibitors of BRD4/BET family bromodomains are showing promise as possible therapeutic agents for cancer and inflammation.

决定酶促反应最大速度Vm的因素是什么?是同一底物,尽管加不同种酶,其Vmax都相同吗?可以画曲线图解释一下吗?可是根据米曼氏方程来看又有点矛盾,Km变大,Vmax也需变大,才可使v变大。所以题目所述到底应该怎么理解呢
酶促反应速率跟底物浓度,pH,温度,酶的 浓度等因素有关,当底物浓度足够高时,酶的浓度相对较低,酶只能与一部分底物结合,导致速率有一个最大值.
调节至最适合温度(一般是37度),合适的酸碱度时,酶的活性最高
反应底物——葡萄糖
反应产物——ATP、乙醇、CO2或ATP、乳酸
有氧呼吸:
反应底物——葡萄糖
反应产物——ATP、CO2、H2O
