Letermovir Action Pathway

Homo sapiens
Letermovir is an antiviral medication that treats cytomegalovirus (CMV) infections and disease in adult CMV-seropositive recipients of an allogeneic hematopoietic stem cell transplant.It was approved by the FDA on November 8, 2017 and is the first of the DNA terminase complex inhibitors for CMV. Cytomegalovirus requires a DNA terminase complex for processing of viral DNA. This complex consists of multiple subunits (pUL51, pUL56, and pUL89). Viral DNA is produced in a single repeating strand which is cut by the DNA terminase complex into individual genomes which can then be packaged into the mature viral particles. Letemovir inhibits the DNA terminase complex, preventing the viral DNA from cutting the DNA and packaging it inside the viral capsid. Thie produces immature, non-infective viruses.

Leucine Biosynthesis

Escherichia coli
Leucine biosynthesis involves a five-step conversion process starting with the valine precursor 2-keto-isovalerate interacting with acetyl-CoA and water through a 2-isopropylmalate synthase resulting in Coenzyme A, hydrogen Ion and 2-isopropylmalic acid. The latter compound reacts with isopropylmalate isomerase which dehydrates the compound resulting in a Isopropylmaleate. This compound reacts with water through a isopropylmalate isomerase resulting in 3-isopropylmalate. This compound interacts with a NAD-driven D-malate / 3-isopropylmalate dehydrogenase results in 2-isopropyl-3-oxosuccinate. This compound interacts spontaneously with hydrogen resulting in the release of carbon dioxide and ketoleucine. Ketoleucine interacts in a reversible reaction with L-glutamic acid through a branched-chain amino-acid aminotransferase resulting in Oxoglutaric acid and L-leucine. L-leucine can then be exported outside the cytoplasm through a transporter: L-amino acid efflux transporter. In the final step, ketoleucine can be catalyzed to form L-leucine by branched-chain amino-acid aminotransferase (IlvE) and tyrosine aminotransferase (TryB). L-Glutamic acid can also be transformed into oxoglutaric acid by these two enzymes. Tyrosine aminotransferase can be suppressed by lecuine, and inhibited by 2-keto-isovarlerate and its end product, tyrosine. 2-ketoisocaproate can not be introduced if 2-keto-isovarlerate inhibit TyrB and IlvE is absent.

Leucine Degradation

Saccharomyces cerevisiae
The degradation of L-leucine starts either in the mitochondria or the cytosol. L-leucine reacts with 2-oxoglutarate through a branch-chain amino acid aminotransferase resulting in the release of ketoleucine and glutamate. The latter compound reacts with ketoisocaproate decarboxylase resulting in the release of carbon dioxide and 3-methylbutanal. The latter compound can then be turned into 3-methylbutanol through a alcohol dehydrogenase
