Crystal of hypoxia inducible factor 1 alpha prolyl hydroxylase
View Patent ↗The crystal structure of ligand-bound EGLN1 catalytic domain of prolyl hydroxylase is disclosed. These coordinates are useful in computer aided drug design for identifying compounds that regulate EGLN1 prolyl hydroxylase and thereby regulate HIF-regulated disorders.
1. A crystal of a protein-ligand complex comprising a protein-ligand complex of an hypoxia inducible factor-1 alpha prolyl hydroxylase (EGLN1) catalytic domain and [(1-chloro-4-hydroxy-isoquinoline-3-carbonyl)amino]acetic acid, wherein the crystal effectively diffracts X-rays for the determination of the atomic coordinates of the protein-ligand complex wherein the resolution of the X-ray diffraction is greater than about 5.0 Angstroms; and wherein the EGLN1 catalytic domain comprises SEQ ID NO: 3, wherein the crystal has unit cell dimensions of a=111±1 Å, b=111±1 Å, and c=40±1 Å, α=90°, β=90°, γ=120° in the hexagonal space group P6 3 .
