    On the Intractability of Protein Folding with a Finite Alphabet of Amino Acids (1999)

    Algorithmica 25 (1999), S. 279-294

    Notes: Abstract. We describe a proof of NP-hardness for a lattice protein folding model whose instances contain protein sequences defined with a fixed, finite alphabet that contains 12 amino acid types. This lattice model represents a protein's conformation as a self-avoiding path that is embedded on the three-dimensional cubic lattice. A contact potential is used to determine the energy of a sequence in a given conformation; a pair of amino acids contributes to the conformational energy only if they are adjacent on the lattice. This result overcomes a significant weakness of previous intractability results, which do not examine protein folding models that have a finite alphabet of amino acids together with physically interesting conformations.

    Notes: [Auszug] IN his paper, “Who built the British Stone Circles?” read at the Dublin meeting of the British Association (NATURE, December 24, 1908, vol. Ixxix., p. 236), Mr. J. Gray says he believes there are few, if any, such stone circles in Ireland. The accompanying photograph shows one at Culdaff ...

    Notes: [Auszug] JUST about three o'clock this afternoon (I had a few minutes previously asked the time at the village post office) I witnessed a remarkable and very beautiful phenomenon. Coming through a woodland walk, I was caught by a heavy downpour of rain. As it was passing away, the sun shone down from a ...

    Notes: [Auszug] REFERRING to a question raised in NATURE of May 20 (P. 345), the writer of the article “Recent Studies on Animal and Plant Life” may accept it as a fact that the primrose flowers are visited both by humble-bees and by moths, among which may be particularly named the humming-bird and bee ...

    Notes: [Auszug] IT appears that in a previous note on this subject (NATURE, June 17, p. 457) clearness may have been sacrificed to brevity. It is not meant that humming-bird and bee hawk-moths can be regarded as usual or frequent agents in the pollination of the primrose. They are mentioned in proof that some ...

    Notes: [Auszug] WITH regard to the flowers of Corydalis claviculata (of the discovery of which species in this neighbourhood I have sent a note to the Journal of Botany), I think Mr. Bennett (vol. ix. p. 484) will find his suspicion that the styles may have been broken off in dissecting to be correct. This may ...

    Notes: [Auszug] A SHORT additional note on Corydalis claviculata may be of interest. A sprig placed in a glass of water and out of the way of insects continues to grow and to bear flowers and fruit with nearly as much regularity as if still rooted to its native bank. The flowers do not gape spontaneously; and, ...

    Notes: [Auszug] IN the notice (NATURE, October 7, p. 141) of the book, “A Chaplet of Herbs,” the expression “chincough” is explained in parenthesis as “(hiccough).” The word is in everyday use in this country, and never in any other sense than the whooping-cough; its etymology being understood as connected ...

    Notes: [Auszug] I HAVE noticed in the laurel and the Spanish chestnut species, in which the leaves have normally a distichous arrangement, that when a vigorous shoot takes a vertical direction—for example, after the stock has been cut down near the ground—the leafage of such a shoot is often quincuncial. The ...
