Biochem J. 1968 Dec;110(3):471-3. doi: 10.1042/bj1100471.

The influence of Cl(-), Br(-), NO(3) (-) and F(-) ions on the visible-absorption spectrum of deionized aspartate aminotransferase was investigated. 2. Except for F(-), these anions caused an increase of the extinction at 430mmu with a concomitant decrease of that at 362mmu. 3. The affinity constants for Cl(-) and NO(3) (-) ions were calculated by a procedure based on the assumption that the anion stabilizes the protonated form of the enzyme chromophore (lambda(max.) 430mmu). 4. The true pK of the chromophore of the enzyme was found to be 5.25.

研究了Cl(-)、Br(-)、NO(3) (-)和F(-)离子对去离子化天冬氨酸转氨酶可见吸收光谱的影响。2. 除F(-)外，这些阴离子导致430nm处吸光度增加，同时362nm处吸光度降低。3. Cl(-)和NO(3) (-)离子的亲和常数是通过一种基于阴离子稳定酶发色团质子化形式（最大吸收波长430nm）这一假设的方法计算得出的。4. 发现该酶发色团的真实pK值为5.25。
