Nerve Growth Factor - Structure

Structure

The structure of NGF was first solved by X-ray crystallography and published in 1991 by McDonald et al. in Nature. NGF forms a cystine knot structure made up of beta strands twisted around each other and linked by disulfide bonds. Most structures are dimeric. At the time this structure was solved, this fold had never been seen before. Hence NGF is the founding member of the nerve growth factor family of structurally conserved proteins.

Famous quotes containing the word structure:

    A special feature of the structure of our book is the monstrous but perfectly organic part that eavesdropping plays in it.
    Vladimir Nabokov (1899–1977)

    The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.
    —For the State of New Jersey, U.S. public relief program (1935-1943)

    The question is still asked of women: “How do you propose to answer the need for child care?” That is an obvious attempt to structure conflict in the old terms. The questions are rather: “If we as a human community want children, how does the total society propose to provide for them?”
    Jean Baker Miller (20th century)
