Table 3.

Inhibition of GABA transamination by the enantiomers of 3-F-GABA (2) using the coupled enzyme assay. Succinic semialdehyde production via turnover of 3-F-GABA was accounted for by subtracting the rate of succinic semialdehyde production for each 3-F-GABA enantiomer from the observed rate of GABA transamination in the presence of that enantiomer.
