11. :Lysidine base pairs with Adenosine in context of a Cytosine to Guanosine base pair. 12. The systematic name of this enzyme class is "'guanosine aminohydrolase " '. 13. This drug is the only approved antiretroviral that is active as a guanosine analogue in vivo. 14. HGPRT is a transferase that catalyzes conversion of hypoxanthine to inosine monophosphate and guanine to guanosine monophosphate. 15. As inhibitor of guanosine monophosphate synthesis in experimental models, the glutamine analogue DON can be used. 16. Thus, the two products are guanosine 5'- diphosphate, 3'- diphosphate and phosphate. 17. Carbovir is a related guanosine analogue that had poor oral bioavailability and thus was withdrawn from clinical development. 18. Two molecules of energy rich guanosine triphosphate ( GTP ) are also important components of the microtubule structure. 19. Additionally, extracellular K + concentration has been found to be controlled by guanine nucleoside guanosine ( Guo ). 20. Adding cytidine or guanosine to the electrophoresis buffer at 1 mM concentration however may protect the DNA from damage.
