A modular Fibonacci sequence in proteins | | M. Dominy

30 Sep 2004 | | Subject: | Genomics; Biomolecules | q-bio.GN q-bio.BM | | Affiliation: | Hagerty Library, Physics Department, Drexel University | | Abstract: | Protein-fragment seqlets typically feature about 10 amino acid residue positions that are fixed to within conservative substitutions but usually separated by a number of prescribed gaps with arbitrary residue content. By quantifying a general amino acid residue sequence in terms of the associated codon number sequence, we have found a precise modular Fibonacci sequence in a continuous gap-free 10-residue seqlet with either 3 or 4 conservative amino acid substitutions. This modular Fibonacci sequence is genuinely biophysical, for it occurs nine times in the SWISS-Prot/TrEMBL database of natural proteins. | | Source: | arXiv, q-bio.GN/0409038 | | Services: | Forum | Review | PDF | Favorites | |
