Which of the following mediates the interaction of newly syn

Which of the following mediates the interaction of newly synthesized polypeptides with SecYEG for transport to the periplasm? A. SecB B. FtsY C. Trigger factor D. Signal sequence

Solution

Answer

The question talking about newly synthesized protein; that reflects post-translational translocation through secYEG, in that situation FtsY excludes from the choices (it associates in Co-translational translocation).Rest of the choices, Sec B,Trigger Factor and Signal Peptide directly take part in newly synthesized protein transport to the periplasm
