The most common methods used for the determination of protein structure are X-ray crystallography or NMR spectroscopy.
Shape of an enzyme specifically shape of its active site determines enzyme specificity .
No, because an enzyme is a protein. The function of each protein is determined by its shape. The protein is only that protein and can do its job only when it is in its specified shape. Since an enzyme is a protein, it has a specific shape that is made for one particular substrate.
i think it's the shape of the active site, the region where the enzyme comes into direct contact with the substrate. the shape of the active site is in turn determined by the structure of the enzyme, which is determined by the number and sequence of amino acids in the primary strucutre.(note that pH affects the shape of the active site as well.) just my guess.
Most proteins including enzymes are very sensitive to heat. When heated it will break the bonds that give the protein its shape. The protein only functions because of its shape. So when we heat a protein/enzyme, it changes its shape and it no longer functions. This process is called denaturation.
What an enzyme does is based on its shape, therefore you would have to change it on a molecular level in order to alter its job.
Hair like enzymes are made of protein. However for a protein to be an enzyme it must have a very specific tertiary structure (shape) and have an active site that has a complementary shape to part of its substrate molecule. ie the enzyme must fit with the thing that it breaks down The tertiary sructure of hair is not highly folded and does not have a complementary shape to a substrate molecule therefore it is not an enzyme
the type and sequence of its amino acids
Yes, enzymes are proteins and it is their sequence of amino acids (primary structure) that determines what kind of an enzyme it is and makes all the enzymes unique and it is the tertiary structure of enzymes that maintains their shape and give rise to the unique active site. When an enzyme is denatured, it loses its tertiary structure and therefore its shape.
The order of amino acids for each protein determines its final three-dimensional shape
The shape of the enzyme must match the shape of the substrate. ... Higher temperature generally causes more collisions among the molecules and therefore ... bonding within the protein molecule change and the molecule changes shape.Can cause the enzyme to change shape? If you mean What causes it to change shape, mainly it's heat.
The type of molecule that is an enzyme is a protein molecule.
There are two significant features of a denatured enzyme: 1) the enzyme does not have biological activity, either by the irreversible binding of an inhibitor or 2) the missing of it's tertiary structure, losing the proper "shape" for its biological functionality.
