This evening, at the ISACS Challenges in Chemical Biology event in Boston, I was part of a conversation suggesting that the concept of chemical biology needed a rebrand. The kids aren’t into chemical biology any more, that scene’s old, man. Of course earlier in the day, I’d been discussing how ‘molecular biologists’ have become ‘chemical biologists’ as the understanding of chemical mechanisms in biology has improved.
The truth is that over the last 48 hours I’ve watched talk after talk illustrating how the mechanics of life are molecular. They are chemical. Bacteria talk to each other using small molecules and peptides that interact with specific residues in a protein, that induces a conformational change, which changes the protein’s available residues within the cell which… and then… and that activates the hydrogen of… etc. The chemical modification of histones by enzyme x alters the reaction landscape of genes by… and so on.
