Saccharopine is an intermediate in the metabolism of amino acid lysine. It is a precursor of lysine in the alpha-aminoadipate pathway which occurs in fungi and euglenids. In mammals and higher plants saccharopine is an intermediate in the degradation of lysine, formed by condensation of lysine and alpha-ketoglutarate.

Reaction

[edit]

The reactions involved, catalysed by saccharopine dehydrogenases, are:

lysine + alpha-ketoglutarate ⇌ saccharopine ⇌ glutamate + 2-aminoadipate 6-semialdehyde

Pathology

[edit]

Saccharopinuria (high amounts of saccharopine in the urine) and saccharopinemia (an excess of saccharopine in the blood) are conditions present in some inherited disorders of lysine degradation.

History

[edit]

Saccharopine was first isolated in 1961 from yeasts (Saccharomyces, hence the name) by Darling and Larsen.[2]
