Quizplus · Accepted Answer

All of the amino acids listed (Aspartate, Cysteine, Lysine, and Serine) can form a covalent bond to the coenzyme pyridoxal phosphate (PLP). PLP, a derivative of vitamin B6, acts as a coenzyme in various enzymatic reactions involving amino acids, including transamination, decarboxylation, and racemization. The covalent bond formation typically involves the amino group of the amino acid and the aldehyde group of PLP.
