2023年10月18日 · Many proteins exist as multimers in their functional state or interact dynamically with other protein molecules, complicating the prediction of their three-dimensional structure and subsequent functional interpretation.
Structural and Functional Properties of Proteins
2021年5月20日 · Many biological functions in the cell are mediated when a protein interacts with one or two other proteins in a phenomenon known as protein–protein interaction (PPI). The chapter concludes by providing an overview of PPIs including their functional importance. Proteins are the ultimate players in the biochemical factory of cell.
