Lecture
This lecture discusses the process of protein production using engineered bacteria, specifically focusing on recombinant E. coli. The instructor explains the advantages of using bacteria as factories for protein synthesis due to their rapid growth and low cost. The lecture outlines the steps involved in creating a protein, starting from knowing the amino acid sequence to translating it into DNA. The process includes cutting and ligating DNA into plasmids, introducing these plasmids into bacteria through heat shock, and selecting for successful transformations using antibiotics. The instructor emphasizes the importance of purification, introducing affinity tags to facilitate this process. The lecture also covers the concept of living materials, where bacteria are engineered to produce biofilms that can be used for various applications. The potential of using engineered bacteria for producing proteins with specific properties is highlighted, showcasing the versatility and power of this technology in molecular biology and materials science.
