L'évolution biologique de mon nom

For the heck of it, I did a BLAST query with my name. BLAST is a fast search algorithm to look up biological sequences in massive databases. The amino acid abbreviations corresponding to the letters my name have arisen throughout millions of years of evolution to find themselves in.... a protein from a bacterial pathogen of plants called Botryotinia fuckeliana (MVRTVNSMIT). Pretty cool eh? The second best (MARTINNMSSSIT) hit is a protein fragment from Coprococcus comes, another dirty sounding name.
========================
Pour le plaisir, j'ai fait une recherche de bases de données avec mon nom. Plus précisement, les abbreviations d'acides aminés (les monomeres de protéines) qui forment les lettres de mon nom. Il s'avere que quelques especes ont evolué d'une maniere a ce que les lettre de mon nom apparaissent dans leur proteines. Ok, ce n'est pas 100% exact, mais presque! La plus apparentée est Botryotinia fuckeliana (serieux!), une bacterie pathogene de plantes. Voir les resultats ci-apres:
