Impact of primary sequence changes on the self-association properties of mammalian cystathionine beta-synthase enzymes.

Abstract excerpt

Cystathionine beta-synthase (CBS) is an evolutionarily conserved enzyme that plays a key role in mammalian sulfur amino acid biochemistry, mutations in which are the cause of classical homocystinuria (HCU), an inborn error of metabolism. Although there is agreement in the literature that CBS is a homomultimer, its precise structure is a source of confusion. Here, we performed a series of experiments examining the...
