Question

Which of the following proteins would NOT have the matched signal sequence?

A. ER retention signal: protein disulfide isomerase (PDI)

B. ER signal sequence: Sec61

C. Peroxisome import signal: Catalase

D. Mitochondrial Matrix signal sequence: Isocitrase dehydrogenase (part of TCA cycle)

E. Thylakoid signal sequence: TIC and TOC

Answer 1

which of the following proteins would not have the matched signal sequence?

answer is (E) Thylakoid signal sequence : TIC and TOC

TIC and TOC complexes are translocons situated in the chloroplast (not in the thylakoid) of an eukaryotic cell that protein edifices that encourage the move of proteins in and out through the chloroplast's layer. It transports proteins that are orchestrated in the cytoplasm over the chloroplast's layer.

Thylakoid signal sequence - peptidase
