Several enzyme functions have been reported for the PDE2.
It may be that extreme pressures interfere with essential enzyme functions.
Magnesium is an important electrolyte needed for proper muscle, nerve, and enzyme function.
Guinea pigs who also have lost this enzyme function 20 million years ago and depend on dietary vitamin C are often used as a human model.
Some 350 enzyme functions depend on it, including the enzyme that generates energy for every cell in the body.
This loss of enzyme function likely causes the characteristic features of these two conditions.
Studies suggest that a lysine close to the active site (at position 12) is also crucial for enzyme function.
Such techniques permit scientists to test for gene activity and enzyme function throughout an organism.
The enzyme functions by providing two glutamate residues as catalytic acid and base.
Water is also central to acid-base neutrality and enzyme function.
