WebAdenine compounds can be converted to GMP by two routes in B. subtilis and in yeast, either via the histidine biosynthetic pathway in which AICAR, an intermediate in the purine biosynthetic pathway, is formed from ATP as a by-product or by a more direct route from adenine to hypoxanthine and then to IMP ( Figure 2 ). WebSeveral methods are commonly used to physically lyse cells to extract proteins, including mechanical disruption, liquid homogenization, high frequency sound waves (sonication), freeze/thaw cycles, and manual grinding. The choice of cell lysis method depends on the type of cells, volume, and sensitivity of proteins being extracted.
