α-Ketobutyric acid is a product of the lysis of cystathionine.
It is also one of the degradation products of threonine, produced by the catabolism of the amino acid by threonine dehydratase.
It can be converted to propionyl-CoA (and subsequently methylmalonyl CoA, which can be converted to succinyl CoA, a CAC intermediate), and thus enter the citric acid cycle.
Conversion in sotolon in French Vin jaune
Vin jaune is marked by the formation of sotolon from alpha-ketobutyric acid.
