Understanding prokaryotic small proteins from context. Prokaryotic small proteins are increasingly recognised to play important biological roles but have been largely overlooked due to the lack of adequate tools to study them. This project aims to develop new methods to identify and predict the functions of small proteins from microbial communities by studying sequence patterns in their genomes. These predicted functions will be confirmed in the laboratory, leading to a catalogue of newly charac ....Understanding prokaryotic small proteins from context. Prokaryotic small proteins are increasingly recognised to play important biological roles but have been largely overlooked due to the lack of adequate tools to study them. This project aims to develop new methods to identify and predict the functions of small proteins from microbial communities by studying sequence patterns in their genomes. These predicted functions will be confirmed in the laboratory, leading to a catalogue of newly characterised small proteins from a diverse range of habitats and geographies. By creating new ways to study the role of small proteins in the global microbiome, we will provide the foundational knowledge required to leverage these proteins for use in biotechnology.

Artificial Self-Replication of Peptide Nanocapsules. Replication is key to the operation of biology, but how molecular replicators arose spontaneously on early Earth remains an open question. The ability of molecules to self-replicate must have come before the development of the highly evolved enzymes that biology currently employs. The aim of this Future Fellowship is to develop a peptide nanocapsule capable of replicating itself nonenzymatically by self-templated ligation, thus offering a plat ....Artificial Self-Replication of Peptide Nanocapsules. Replication is key to the operation of biology, but how molecular replicators arose spontaneously on early Earth remains an open question. The ability of molecules to self-replicate must have come before the development of the highly evolved enzymes that biology currently employs. The aim of this Future Fellowship is to develop a peptide nanocapsule capable of replicating itself nonenzymatically by self-templated ligation, thus offering a platform that possesses the traits needed for Darwinian evolution to emerge. By obtaining a better understanding of the design and function of self-replicating systems, this project is expected to transform our understanding of some of the key chemical principles needed for life's emergence.Read moreRead less
