Examples of lysine

• Similarly, the basic residues (arginine and lysine) have virtually identical periods in each of the two segments.

• 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.
