13. Which of the following description about bacterial protein secretion pathway is not correct?
(A) ABC protein secretion pathway can secrete proteins which usually have N- terminal secretion signals.
(B) Some type III secretion machinery is syringe-shaped and secretes virulence factors directly into host cells.
(C) In some G(-) bacteria, proteins can first be removed across the plasma membrane through Tat pathway, then delivered to type II secretion system and passed through the outer membrane.
(D) Type IV secretion pathway can secrete proteins and transfer DNA during conjugation.
(E) Type V secretion pathway can transport some autotransporters through the outer membrane.
