Which of the following mediate the interaction of newly synthesized polypeptides with SecYEG for transport to the periplasm?

A- Sec B

B- Signal recognition particle

C-Trigger factor

D-FtsY

Answer is NOT A

Solution

The answer is B AND D because

it is because of the signal recognition particle receptor which can be either SR or FtsY,the ribosome secretory protein chain is usually transferred from SRP to the Sec-translocase (in other words the periplasm).
