CdsA is involved in biosynthesis of glycolipid MPIase essential for membrane protein integration in vivo [PDF]
, 2021 MPIase is a glycolipid that is involved in membrane protein integration. Despite evaluation of its functions in vitro, the lack of information on MPIase biosynthesis hampered verification of its involvement in vivo. In this study, we found that depletion
