WebThe Escherichia coli signal recognition particle (SRP) receptor, FtsY, plays a fundamental role in co-translational targeting of membrane proteins via the SRP pathway. Efficient targeting relies on membrane interaction of FtsY and heterodimerization with the SRP protein Ffh, which is driven by detachment of α helix (αN1) in FtsY. WebNov 16, 2004 · Besides the NG domain, Ffh has a C-terminal methionine-rich domain, called the M domain ().The M domain provides the binding module for 4.5S RNA (18, 19), which facilitates Ffh·FtsY complex formation (20, 21).It is widely accepted that the M domain also contains the primary binding site for signal sequences (7, 22), although recent data …
