'''Insertase''' (Ins) catalyzes the insertion of proteins into the prokaryotic plasma membrane. Ins interacts with its substrate in a groove-like structure at an ampiphilic protein-lipid interface allowing the transmembrane segments of the substrate to slide into the lipid bilayer<ref>PMID:27879020</ref>. | '''Insertase''' (Ins) catalyzes the insertion of proteins into the prokaryotic plasma membrane.
