Abstract
Summary
1. Glucose, acid degraded glucose and the Christman-Williams factor exhibit significant stimulation of the aspartic acid deaminase system of the living cell. 2. Acid treatment is not required for the stimulatory activity of glucose. 3. None of these carbohydrates is capable of stimulating the thoroughly dried cell or the cell-free sonic extract. 4. The kinetics of the living cell approach those of the cell-free and dried preparation only if glucose is supplied. 5. It appears likely that the stimulatory effect of carbohydrates on this system is an indirect one perhaps concerned with the permeability of the cell membrane to the amino acid substrate.
