Valganciclovir Action Pathway

Homo sapiens
Valganciclovir is an antiviral medication used to treat cytomegalovirus (CMV) retinitis in patients diagnosed with acquired immunodeficiency syndrome (AIDS). Valganciclovir is a prodrug of ganciclovir. After administration, valganciclovir is rapidly converted to ganciclovir in the intestine or liver by intestinal or hepatic esterases.Ganciclovir is transported into the blood and to the infected cells. It is then converted to the active form by a virus-encoded cellular enzyme, thymidine kinase, which catalyzes phosphorylation of ganciclovir to ganciclovir monophosphate. Ganciclovir monophosphate is converted into the diphosphate by cellular guanylate kinase then into the triphosphate by a number of cellular enzymes. Ganciclovir triphosphate inhibits the activity of DNA polymerase by competing with its substrate dGTP. Ganciclovir triphosphate also gets incorporated into viral DNA, but since it lacks the 3'-OH group which is needed to form the 5′ to 3′ phosphodiester linkage essential for DNA chain elongation, this causes DNA chain termination, preventing the growth of viral DNA. Less Viral DNA is transported into the nucleus, therefore, less viral DNA is integrated into the host DNA. Less viral proteins produced, fewer viruses can form.

Valine Biosynthesis

Pseudomonas aeruginosa
The pathway of valine biosynthesis starts with pyruvic acid interacting with a hydrogen ion through a acetolactate synthase / acetohydroxybutanoate synthase or a acetohydroxybutanoate synthase / acetolactate synthase resulting in the release of carbon dioxide and (S)-2-acetolactate. The latter compound then interacts with a hydrogen ion through an NADPH driven acetohydroxy acid isomeroreductase resulting in the release of a NADP and an (R) 2,3-dihydroxy-3-methylvalerate. The latter compound is then dehydrated by a dihydroxy acid dehydratase resulting in the release of water and isovaleric acid. Isovaleric acid interacts with an L-glutamic acid through a Valine Transaminase resulting in a oxoglutaric acid and an L-valine. L-valine is then transported into the periplasmic space through a L-valine efflux transporter.

Valine Degradation

Arabidopsis thaliana
The degradation of valine starts either in the mitochondria or the cytosol. L-valine reacts with 2-oxoglutarate through a branch-chain amino acid aminotransferase resulting in the release of L-glutamate and 3-methyl-2-oxobutanoate. The latter compound reacts with 2-oxoisovalerate carboxy-lyase resulting in the release of carbon dioxide and isobutanal. Isobutanal can then be turned into isobutanol through a alcohol dehydrogenase

Valine Degradation

Streptomyces avermitilis
Valine degradation is a crucial metabolic pathway involved in breaking down the essential amino acid valine into molecules that can enter the tricarboxylic acid (TCA) cycle, thereby contributing to energy production and various biosynthetic processes. This pathway involves several enzymatic reactions that sequentially convert valine into succinyl-CoA, a key TCA cycle intermediate. This degradation process not only aids in cellular energy generation but also provides precursors for the synthesis of other important biomolecules.
