CRYSTAL COMPRISING HUMAN IMMUNODEFICIENCY VIRUS ENVELOPE GLYCOPROTEIN gp120, COMPOUNDS INHIBITING CD4-gp120 INTERACTION, COMPOUNDS INHIBITING CHEMOKINE RECEPTOR-gp120 INTERACTION, MIMICS OF CD4 AND gp120 VARIANTS

摘要

The subject invention provides a crystal suitable for X-ray diffraction comprising a polypeptide having an amino acid sequence of a portion of a Human Immunodeficiency Virus envelope glycoprotein gp120. The subject invention also provides the above-described crystals, wherein the crystal is arranged in a space group P2221, so as to form a unit cell of dimensions a=71.6 ANGSTROM , b=88.1 ANGSTROM , c=196.7 ANGSTROM , and which effectively diffracts X-rays for determination of the atomic coordinates of the gp120 to a resolution of 2.5 ANGSTROM or better. The subject invention additionally provides compounds inhibiting the CD4-gp 120 interaction, compounds inhibiting chemokine receptor-gp120 interaction, mimics of CD4, gp120 variants and uses thereof.
