What are the protein amino acids modified during N-linked glycosylation? What are the steps involved in the addition of the en masse carbohydrate complex to a protein and its modification in the ER?
Homework Answers
n-linked glycolysation :
all the N_LINKED CARBOHYDRATES are linked through N-ACETYKGLUCOSAMINE and AMINO ACID ASPARGINE -it starts with addition of 14-sugar precursor with asparagine amino acid
-CARBOHYDRATES are attached to PROTIEN IN TWO WAYS :N_LINKEd and o-linked GLYCOLYSATIOM
carbohydrates are attached to protiens by nitrogen or oxygen.
MODIFICATION IN ER:
n-linked glycolysation begins in ER
path taken by polypeptide through secretary pathwat starts with its translocation across or into ER membrane.
it must be folded andmodified correctly in ER before being transported via golgi apparatusto cell surface and futher destinations.

What would happen in each of the following cases? Assume in each case that the protein involved is a soluble protein, not a membrane protein. You add a signal sequence (for the ER) to the N-terminal end of a normally cytosolic protein. You change the hydrophobic amino acids in an ER signal sequence into charged amino acids. You change the hydrophobic amino acids in an ER signal sequence into other hydrophobic amino acids. You move the N-terminal ER signal sequence...

G alpha z (Gaz) is a protein of 355 amino acids in length. It is synthesized in the cytoplasm and has no signal sequence, nor a start-transfer sequence, nor a nuclear import sequence or patch. After its initial synthesis, Gaz is bound by another protein called a palmitoyltransferase, which covalently attaches a fatty acid called palmitate to a cysteine side chain near the N-terminus of Gaz. This lipid modification allows Gaz to associate with the inner face of the plasma...
