Invited Speaker International Peptide Symposium 2023

Our work studies the interplay of biomolecules – proteins, sugars, lipids and their modifications.
Synthetic Biology’s development at the start of this century may be compared with Synthetic
Organic Chemistry’s expansion at the start of the last; after decades of isolation, identification,
analysis and functional confirmation, the future logical and free-ranging redesign of biomacromolecules
offers tantalizing opportunities to dissect mechanism and control function in physiology
and biology.
This lecture will cover past and emerging areas in our group in the manipulation of biomolecules
with an emphasis on new bond-forming and bond-breaking processes compatible with biology
and using those to understand molecular mechanisms.
:
(i) New methods: the development of precise methods that may be applied to biology at a posttranslational
level, generating minimal ‘scars’ or ‘traces’ (ideally ‘trace’-less), could allow broad
control of function. This will allow applications beyond simple ‘labeling biology’ or retrieval biology’.
The development of chemo- and regio-selective methods with potential to posttranslationally
‘edit’ biology in this way, applied under benign conditions to redesign and reprogramme
the structure and function of biomolecules, will be presented.
(ii) ‘Synthetic Biologics’ and their applications: biomimicry; functional recapitulation; effector
[drug/agrochemical/gene/radio-dose] delivery; selective protein degradation; inhibitors of pathogen
interactions; non-invasive presymptopmatic disease diagnosis; probes and modulators of in
vitro and in vivo function illustrate possible resulting technologies.
