Molecular architecture of the multifunctional collagen lysyl hydroxylase and glycosyltransferase LH3

Abstract

Lysyl hydroxylase 3 (LH3) catalyzes collagen lysine hydroxylation and their subsequent O-linked glycosylation. Here the authors provide mechanistic insights into the lysyl hydroxylase and glycosyltransferase activities of LH3 by determining the crystal structures of full-length human LH3 bound to cofactors and donor substrates.
