Consistencies Of Individual Dna Base-Amino Acid Interactions In Structures And Sequences, Brooke Lustig, R L. Jernigan

Faculty Publications, Chemistry

Amino acid-amino acid interaction energies have been derived from crystal structure data for a number of years. Here is reported the first derivation of normalized relative interaction from binding data for each of the four bases interacting with a specific amino acid, utilizing data from combinatorial multiplex ONA binding of zinc finger domains [Desjarlais, J. R. and Berg, J. M. (1994) Proc. Natl. Acad. Sci. USA, 91, 11099–11103]. The five strongest Interactions are observed for lysine-guanine, lysine-thymine, arginine- guanine, aspartic acid-cytosine and asparagineadenine. These rankings for interactions with the four bases appear to be related to base-amino acid partial charges. …
