A transmembrane protein has its N-terminus in the lumen of the ER, its C-terminus in the cytoplasm, and it spans the membrane fi
ve times. What are all the signals that this protein displayed, including any that may have been cleaved? (In the following options "STS" stands for "stop transfer sequence")
N-terminal signal sequence --> STS --> internal signal sequence --> STS --> internal signal sequence --> STS
Explanation:
Steroid Sulfatase (STS) is a signal localized in the endoplasmic reticulum, it catalyzes the desulfation reaction
N-Terminal is the protein domain that is outside of the cell membrane
The internal signal sequence directs the protein to the membrane of the endoplasmic reticulum, this signal is also responsible for open the membrane pore
This discharge, identified as ocean, can modify the salinity and reduce the quantity of oxygen in the ocean at the dumping place, emphasizing or sacrificing animals not used to the greater levels of salt.
Desalination supplies to global warming and needs huge quantities of energy.
Non vascular plants are very small because their lack of a vascular system means they do not have the mechanics required for transporting food and water far distances. ... Non vascular plants are small, simple plants without a vascular system. They do not have a phloem or xylem.
