(2000b) also have emphasized the likely role of the lysine in stabilizing movement of negative charge from the orotidine carboxyl group to thepyrimidinering.From theCambridge English CorpusIt belongs to the chemical family of pyrimidines.FromWikipediaThis example is from Wikipedia and may be reused under a CC BY-SA license.This enzyme participates in purine metabolism andpyrimidinemetabolism.FromWikipediaThis example is from Wikipedia and may be reused under a CC BY-SA license.The common characteristics of the novel enzymes are their capability to bypass lesions likepyrimidinedimers.From theCambridge English CorpusFurthermore, the purine andpyrimidinebases need to be covalently bound, in b-orientation, with the 1k carbon of ribose to form nucleosides.From theCambridge English CorpusThe condensation of nucleo-bases adenine or guanine with sugar ribose gives only minute amounts of nucleosides with correct stereochemistry, and synthesis ofpyrimidinenucleosides is even more difficult.From theCambridge English CorpusPyrimidinedicarboxamides bind to this side pocket, which increases the selectivity.FromWikipediaThis example is from Wikipedia and may be reused under a CC BY-SA license.However, later he corrected himself and expanded his initial studies, showing that the end products actually were pyrimidines.FromWikipediaThis example is from Wikipedia and may be reused under a CC BY-SA license.
