Ubiquitin can be attached to lysine residues of cellular proteins either as a single unit (monoubiquitin) or in the form of branched, polyubiquitin chains. It contains a positively charged arginine or lysine residue at every third position. Placental transport of leucine and lysine is reduced in intrauterine growth restriction. The first lysine is located near the -phosphate, whereas the second lysine is near the ribose moiety. Both hordeins and zeins are deficient in the essential amino acid lysine. Production of arginine dihydrolase and lysine and ornithine decarboxylases was uniform. Structural and functional demonstration of arginine-138 as a key catalytic residue that cannot be replaced by lysine. The ribose oxygens preferentially interact with mainchain atoms (39 %, 31 % of which are glycines) followed by arginine\\lysine and aspartate\\glutamate. This was also observed when labelled lysine and alanine were used instead of arginine (unpublished observations). We also determined that this phenomenon was independent of the structure of lysine molecules. Combined administration of human corticotropinreleasing hormone and lysine vasopressin induces cortisol escape from dexamethasone suppression in healthy subjects. Interactions between the hydrophobic domains contribute to correctly juxtaposing lysine residues prior to crosslink formation. Is lysine the limiting amino-acid in the proteins of wheat, maize or oats? In other words there are usually a small number of lysine-lysine crosslinks that occur between identically located residues.
