Cards

Term
Moleten Globule
Definition
First part of Protein folding. Large, unfolded, large volume, no secondary structure, accessible to proteases and chaperones.
Term
Naitive Shape
Definition
A fully folded protein. Compact and Active
Term
Dolichol-Phosphatase
Definition
First sugar to be attached to Asn Residues in N linked Glycosylation. Takes place in the ER
Term

Term
Anterograde (direction)
Definition
Proteins exit the cell or are placed on its surface
Term
Retrograde (direction)
Definition
Endocytosis or retrieval of protein.
Term
COAT proteins
Definition
proteins required for exocytosis or budding. "You need to put your coat on before you leave"
Term
