E.Coli Secretion

1

What is the main problem of protein translocation?

1

Proteins to be secreted directly after translation have a peptidase sequence at the C-terminus

1

Which of the following parts of the peptidase sequence are closest to the N-terminus?

1

There are 1-2 basic residues in the signal sequence, but the hydrophobic sequence is variable in length

1

When a protein is transcribed with the Peptidase signal site, what protein binds to its hydrophobic region?

1

Ftsy transfers the protein into the pore

1

Which of the following provide the driving force for protein translocation across the membrane

1

What binds to the nascent polypeptide if Post-Translational Translocation takes place?

1

Post-Translational Translocation sequences have a string of hydrophobic amino acids, same as in Translational Translocation

1

What is the role of Sec_ ?

1

What forces are required to get a Post-Translational Translocation through the pore?

1

Once inside the required membrane, what protein removes the peptide sequence?

1

The protein only folds after the signal sequence is cleaved
