一般說明
牛胰腺脱氧核糖核酸酶I(DNase I)是DNA小沟相互作用的核酸酶,特异性相对较低。该蛋白质由两个中心β 折叠构成,而每个折叠由六个β-链所组成。该结构被大量的环以及α-螺旋区域包围。该酶与核酸外切酶III具有结构相似性。DNase I是研究得最透彻的哺乳动物来源的内切酶之一。它是一种双链特异性内切核酸酶,需要二价阳离子激发最大活性。

Human lungs are constantly exposed to bacteria in the environment, yet the prevailing dogma is that healthy lungs are sterile. DNA sequencing-based studies of pulmonary bacterial diversity challenge this notion. However, DNA-based microbial analysis currently fails to distinguish between DNA

Nucleotide-sugar transporters (NSTs) facilitate eukaryotic cellular glycosylation by transporting nucleotide-sugar conjugates into the Golgi lumen and endoplasmic reticulum for use by glycosyltransferases, while also transferring nucleotide monophosphate byproducts to the cytoplasm. Mutations in this family of proteins can cause a
