Table 1. Thermodynamic parameters of D- and L-aspartate binding at high (300 mM) and low (75 mM) Na⁺ concentration.

Substrate/ Na⁺	K_d (µM)	ΔH (cal mol⁻¹)	ΔS (cal mol⁻¹ K⁻¹)
L-aspartate/300 mM NaCl	0.12 ± 0.04	−1.61 (±0.08) x 10⁴	−22.1 ± 2.2
D-aspartate/300 mM NaCl	0.47 ± 0.17	−1.48 (±0.11) x 10⁴	−20.6 ± 3.6
L-aspartate/75 mM NaCl	1.04 ± 0.39	−1.22 (±0.13) x 10⁴	−13.2 ± 5.2
D-aspartate/75 mM NaCl	5.66 ± 1.59	−1.14 (±0.41) x 10⁴	−14.3 ± 14.3^*

^*At low Na⁺ concentrations high errors prevented accurate measuring of ΔS values.
