De novo protein design is a computational approach that involves designing and synthesizing entirely new protein structures from scratch, without relying on existing natural proteins as templates.
It addresses the limitations of traditional protein engineering methods, which often rely on modifying existing proteins rather than creating entirely new ones with novel functions.
The process begins by defining the desired function of the protein. Computational algorithms are then used to predict potential sequences and structures that could achieve this function. Once promising designs are identified, they are synthesized in the lab and tested for their ability to fold into the predicted structure and perform the intended function.
Manufacturing involves synthesizing the designed DNA sequences using techniques like PCR amplification followed by gene synthesis. These genes are then inserted into expression vectors and expressed in host cells such as bacteria or yeast to produce the protein.
The build process includes computational design, sequence optimization, protein synthesis, and functional testing. Computational tools play a crucial role in predicting structural stability and function before physical synthesis.
