Biochemical systematics

Cell cycle is one of the physiological processes in which the role of uhiquitin—proteasome-mediated proteolysis is well established. With the advent of yeast mutants that interfered with various phases of the cell cycle, cyclin-dependent kinases (Cdks) were found to have a critical role in regulating the cell cycle. Typically, Cdks activated hy regulatory proteins are known as cyclins. Different Cdk—cyclin complexes are formed at specific stages of the cell cycle such as the S-phase (in which DNA synthesis occurs) and the metaphase. The transition from metaphase to anaphase depends on degradation of cyclins. " " Systematic biochemical studies showed that cyclins were substrates for the uhiquitin—proteasome pathway (Table 5).

To the authors knowledge little is being done in order to explain these interesting facts. We may wonder how the Fagopyrum and Hypericum species protect themselves against radiation damage. Except for research on chlorophyll too little systematic biochemical work is done on photochemical reactions. It is hoped that the recently published... 

For this reason dual terminology is in use for the aza analogs. The first, derived from the principal pyrimidine and purine derivatives by means of the prefix aza- is used almost exclusively in biochemical papers in organic chemistry is it used together with the systematic names) wherever it is desired to compare the properties of the natural bases and of their aza analogs. The systematic terminology is naturally used in the older literature where no biochemical aspects of the compounds were considered, and in some newer work of strictly chemical nature. Since the numbering of the substituents is in some cases different for the different systems, we shall discuss this in more detail later. ... 

The 8-aza analogs are formally derived by substitution of the methine group in position 8 of the purine ring. The names thus derived preserve the numbering of the purine ring (146), and are frequently used in papers of biochemical character, but in chemical papers only along with systematic names.
