ResearchÌýAbstract

Antimicrobial Peptides (AMPs) are usually broad spectrum antimicrobials that are being investigated by various groups for use to treat antibiotic-resistant infections. However, the application of AMPs is limited due to their susceptibility to degradation and toxicity to host cell. These deficiencies may be overcome by the incorporation of non-canonical amino acids (NCAA) into the amino acid sequence of AMPs. This is an attractive route for improving the properties of antimicrobial peptides and to expand their applications beyond the clinical setting.

Whilst solid-state chemical synthesis of peptides are used for such incorporations in small peptides it would be a challenge to synthesise larger ones in this fashion. The expansion of the genetic code for the incorporation of NCAA is an alternative method that is gaining traction. It offers a more sustainable and environmentally friendly way of producing peptides containing modified amino acids. My research will entail enhancing the properties of AMPs by introducing NCAAs and eventually engineering microbial cell factories (E. coli or other agents) to produce NCAA-containing AMPs.

BIOGRAPHY

George Enninful holds a Masters’ of Engineering degree from the Hanbat National University South Korea (HBNU, 2020). Prior to that he was a research trainee in the Molecular Biotechnology lab, Department of Chemical and Biological Engineering at HBNU. After a bachelors in Biochemistry in 2015 from Kwame Nkrumah University of Science and Technology (KNUST, Ghana), George took up the role of research assistant in microbiology for 2 years.

His research interests lie in recombinant protein expression systems, engineering microbial cell factories, synthetic biology and combating antimicrobial resistance through Antimicrobial Peptides.
