bisc 261 chapter 10: gene expressionTest with Questions with 100% Correct
Answers
A system used to transport folded proteins across the plasma membrane in bacteria
and some archaea; some eukaryotes have homologues of the Tat system in their
chloroplasts and mitochondria - Answer Tat system
The membrane-bound enzyme that cleaves the signal peptide from a polypeptide as it
is transported through the plasma membrane - Answer signal peptidase
A periplasmic enzyme that catalyzes the formation of disulfide bonds as a
polypeptide folds into its functional form - Answer protein disulfide isomerase
A sequence at the C-terminus of some Gram-positive secreted proteins that directs the
protein to sortase enzymes for anchoring to the peptidoglycan - Answer sorting signal
An enzyme that catalyzes the attachment of a secreted protein to the
surface peptidoglycan of a Gram-positive bacterium - Answer sortase
, A pathway in Gram-negative bacteria that translocates proteins across the outer
membrane after they have been translocated across the plasma membrane by the
Sec system - Answer type V secretion system
A system found in Proteobacteria in which a periplasmic pseudopilus pushes secreted
proteins through an outer membrane barrel - Answer type II secretion system
A two-step protein secretion system in the Bacteroidetes that guides proteins to
the outer surface of the cell - Answer type IX secretion system
See ABC protein secretion pathway. A structure found in proteobacteria to
transport proteins from the periplasm through the outer membrane - Answer type I
secretion system
A system in Gram-negative bacteria that secretes virulence factors and injects them
into host cells - Answer type III secretion system/injectosomes
A system in Gram-negative bacteria that secretes proteins; some Gram-negative
and Gram-positive bacteria use this secretion system to transfer DNA during
bacterial conjugation - Answer type IV secretion system
A protein secretion system in Gram-negative bacteria that is similar in structure to
the machinery used by some bacteriophages to insert their DNA into host cells -
Answer type VI secretion system
A protein secretion system in Gram-positive bacteria that translocates proteins
across the plasma membrane - Answer type VII secretion system
