The structural superposition of native EDN (PDB: 1GQV [ 62 ]), EDN-RI (PDB: 2BEX [ 41 ]), native ANG (PDB: 4AOH [ 21 ]), ANG–RI (PDB: 1A4Y [ 39 ]) against AEH molecules show that the conformat... onal changes observed are unique to AEH molecules.
4 Conclusions We have compared the solution structure of ANG (determined by nuclear magnetic resonance) (PDB: 1AWZ [ 67 ]) with the high resolution structure of ANG in the crystalline state (determined by X-ray crystallography, PDB: 4AOH [ 21 ]) and found that the loop regions retain similar conformation in both structures.
A detailed analyses of the catalytic site of AEH against a few members of the RNase A superfamily determined at atomic resolution – the prototype molecule RNase A (PDB: 2E3W, 1.05 Å resolution [ 61 ]), EDN (PDB: 1GQV, 0.98 Å resolution [ 62 ]), and ANG (PDB: 4AOH, 1.04 Å resolution [ 21 ]) showed the presence of a highly conserved solvent network involving four water molecules (labelled as 1–4 in Fig. 2 A–E).
