The crystal structure of Drosophila DDC and the site-directed mutagenesis study of the enzyme demonstrate that T82 is involved in substrate binding and that H192 is used not only for substrate interaction, but for cofactor binding of drDDC as well. Through comparative analysis, the results also provide insight into the structure …

WebbOnce within a cell, these surface proteins can be either destroyed or “recycled” back to the membrane. The cell surface biotinylation assay provides researchers with a way to study these phenomena. The technique makes use of a derivative of the small molecule biotin, which can label surface proteins and then be chemically cleaved. Webb首先是概念：蛋白质和多肽： 多肽是三个或三个以上氨基酸缩水形成的肽链.多肽到一定长度后,可以被认为是蛋白质了,（这个长度不确定,有的20多个氨基酸算,有的50多个算,没有一个固定标准,只是根据多肽的功能,来确定是否为蛋白质）. 顺着上面的意思,蛋白质就是多肽,或由多肽组成的.后半句意思是,蛋白质除了多肽外,可以对：1.多肽进行修饰,比如糖基化,烷基化, …

Protein modifiers include but are not limited to BSA or serum. This article has not been copyedited and formatted. WebbHowever, we were not able to calculate the exact turnover number of rat and mouse COX-1 and COX-2 proteins because the recombinant rat and mouse COXs are not commercially available. To estimate mouse turnover numbers, we used cell lysate prepared from Raw 264.7 cells after LPS stimulation, which is a standard method to selectively induce COX-2.
