Key points
● Determining the crystal structure of YidC, a membrane protein insertase that inserts proteins into the cytoplasmic membrane, for the first time in the world
● Clarifying details of the molecular mechanism of protein insertion into the plasma membrane, phenomena common to organisms from bacteria to humans
● Contributing to the advancement of life sciences research and laying the foundations for the development of novel drugs
