Deskripsi
Prew et al. uncovered a structural basis for human VLCAD deficiency that arises from point mutations within the enzyme’s membrane-binding region, which was shown to fold as a putative α-helical hairpin. Helix-breaking mutations selectively disrupt membrane interaction and thus homeostatic function.
