Each protein normally folds into a single stable conformation. This conformation, however, often changes dramastically when the protein interacts with other molecules in the cell.
举一反三
- GTP-binding proteins act as _______________: they are in their active conformation when GTP is bound, but they can hydrolyze this GTP to GDP, which releases a phosphate and flips the protein to an inactive conformation.
- The most stable conformation for cyclohexane is chair conformation.
- β-turns in protein molecules belong to the protein's hierarchical structure? A: Primary structure B: Secondary structure C: Tertiary structure D: Side chain conformation
- The most stable conformation for cyclohexane is chair conformation. A: 正确 B: 错误
- Many proteins can be grouped into protein families, in which each family member has an amino acid sequence and a three-dimensional conformation that closely ________ those of the other family members.
