Abstract:
-Nerve growth factor (
-NGF) is a 118 amino acid residue polypeptide with an important role in the survival and development of certain neuronal populations. A
-NGF purified from cobra venom was crystallized by the hanging-drop vapor diffusion method. The crystals belong to the tetragonal space group P41212 (or its enantiomorph P43212) with unit-cell parameters a=b=61.75, c=154.40A
. X-ray data from these crystals were collected to 3.2 A
resolution. Analysis of the packing density shows that the asymmetric unit probably contains two molecules. The self-rotation calculation implied that a
-NGF dimer might exist in the asymmetric unit.
