Protein-protein interactions (PPIs) play central roles in most biological processes. Studying PPIs is a fundamental step in understanding the molecular basis of cellular processes such as cell-cell contact, enzyme activity, and transient assembly of signaling complexes or cellular structures. In this work, we employed a combination of biophysical and biochemical methods to characterize PPIs, with a focus on interactions between structured domains and intrinsically disordered regions or peptide substrates.The subject of Chapter two is prolyl isomerase Ess1, which is an essential enzyme found in Saccharomyces cerevisiae. Ess1 regulates the transcription and co-transcriptional RNA processing by catalyzing the isomerization of serine-proline …
