Spermidine and Spermine Biosynthesis
smpdb.ca/view/SMP0000445MetabolicSpermidine and spermine are produced in many tissues, as they are involved in the regulation of genetic processes from DNA synthesis to cell migration, proliferation, differentiation and apoptosis. … The Spermidine and Spermine Biosynthesis pathway highlights the creation of these cruicial polyamines.
Phenylalanine and Tyrosine Metabolism
smpdb.ca/view/SMP0000008Metabolicinto polypeptides (via tyrosyl tRNA synthetase and phenylalyl tRNA synthetase) and the conversion of phenylalanine to tyrosine via phenylalanine hydroxylase. … Tyrosine can be converted into L-DOPA, which is further converted into dopamine, norepinephrine (noradrenaline), and epinephrine (adrenaline).

smpdb.ca/view/SMP0000032Metabolicand acetyl-CoA) and glucose (succinyl-CoA). … Leucine is ultimately converted into acetyl-CoA and acetoacetate; isoleucine into acetyl-CoA and succinyl-CoA; and valine into propionyl-CoA (and subsequently succinyl-CoA).
Threonine and 2-Oxobutanoate Degradation
smpdb.ca/view/SMP0000452Metabolic2-oxobutanoate, also known as 2-Ketobutyric acid, is a 2-keto acid that is commonly produced in the metabolism of amino acids such as methionine and threonine. … E1 binds the 2-oxobutanoate to the lipoate on E2, which then transfers the propionyl group to coenzyme A, producing propionyl-CoA and reducing the lipoate.
Apoptotic DNA Fragmentation and Tissue Homeostasis
smpdb.ca/view/SMP0063772SignalingICAD and CAD exist in the nucleus in normal cells and is a major endonuclease in apoptosis. Its activation is normally caspase dependent. … EndoG resides in mitochondria in normal cells and travels to the nucleus, where it fragments chromosomal DNA upon activation of apoptosis.

smpdb.ca/view/SMP0123283MetabolicIf not cleared, it can reduce cardiomyocyte contractility and weaken cardiac efficiency, leading to systolic dysfunction and heart failure. … Arginine from the diet is absorbed into systemic circulation and enters hepatocytes through an amino acid transporter, where it undergoes a series of metabolic reactions.
Metabolism and Physiological Effects of Xanthine
smpdb.ca/view/SMP0124865MetabolicThe purines are guanine and adenine. These undergo metabolism in the liver to form xanthine. Adenine forms adenosine through the enzyme purine nucleoside phosphorylase. … Xanthine then enters the blood where it can have detrimental effects on other organs such as the kidney (causing renal failure) and the blood vessel (causing endothelial dysfunction).
Metabolism and Physiological Effects of Kynurenine
smpdb.ca/view/SMP0125524DiseaseIn the blood it travels to the liver and is transported into a hepatocyte by an amino acid transporter. … Kynurenine is shown to activate aryl hydrocarbon receptors that can lead to renal impairment, apoptosis, and kynurenine has also been found to disrupt the electron transport chain and oxidative phosphorylation
