WebApr 18, 2000 · Unlike FtsY-depleted cells, where expression of SecY is inhibited (Fig. 2B), in Ffh-depleted cells, SecY expression remains unchanged (Fig. 4B). Thus, the effect of Ffh depletion differs from FtsY depletion, probably because Ffh depletion prevents proper membrane protein assembly (9–11) but has little or no effect on expression per se. 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 … binax now work for international travel
