Description

Lysine (abbreviated as Lys or K) is an alpha-amino acid. The L-isomer is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. It is classified as a polar, basic amino acid, because of the positively charged nature of the amino-alkyl side chain. In yeast, lysine is synthesized from aspartic acid (aspartate). Specifically, L-aspartate is first converted to L-aspartyl-4-phosphate by aspartokinase (or Aspartate kinase). Subsequently, beta-aspartate semialdehyde dehydrogenase converts this into beta-aspartyl-4-semialdehyde (or beta-aspartate-4-semialdehyde) through an NADH-dependent reaction. After this step, Dihydrodipicolinate synthase adds a pyruvate group to the beta-aspartyl-4-semialdehyde, and two water molecules are removed. This causes cyclization and gives rise to 2,3-dihydrodipicolinate. This product is reduced to 2,3,4,5-tetrahydrodipicolinate by dihydrodipicolinate reductase. Tetrahydrodipicolinate N-acetyltransferase opens this ring and gives rise to N-succinyl-L-2-amino-6-oxoheptanedionate (or N-acyl-2-amino-6-oxopimelate). N-succinyl-L-2-amino-6-oxoheptanedionate is converted into N-succinyl-LL-2,6-diaminoheptanedionate (N-acyl-2,6-diaminopimelate). This reaction is catalyzed by the enzyme succinyl diaminopimelate aminotransferase. A glutaric acid molecule is used in this reaction and an oxoacid is produced as a byproduct. N-succinyl-LL-2,6-diaminoheptanedionate (N-acyl-2,6-diaminopimelate)is converted into LL-2,6-diaminoheptanedionate (L,L-2,6-diaminopimelate) by succinyl diaminopimelate desuccinylase (acyldiaminopimelate deacylase). A water molecule is consumed in this reaction and a succinate is produced a byproduct. LL-2,6-diaminoheptanedionate is converted by diaminopimelate epimerase into meso-2,6-diamino-heptanedionate (meso-2,6-diaminopimelate). Finally meso-2,6-diamino-heptanedionate is converted into L-lysine by diaminopimelate decarboxylase. Lysine catabolism is unusual in the way that the ε-amino group is transferred to alpha-ketoglutarate and into the general nitrogen pool. The reaction is a transamination in which the ε-amino group is transferred to the alpha-keto carbon of alpha-ketoglutarate forming the metabolite, saccharopine. Saccharopine is immediately hydrolyzed by the enzyme alpha-aminoadipic semialdehyde synthase in such a way that the amino nitrogen remains with the alpha-carbon of alpha-ketoglutarate, producing glutamate and alpha-aminoadipic semialdehyde. The ultimate end-product of lysine catabolism is acetoacetyl-CoA.
