Abstract
Inhibition of anion transport by the arginine specific reagents phenylglyoxal and 1,2 cyclohexandione depends on the pH and anion concentration in the medium. At pH 8.0, chloride ions protect the transport system against inhibition by PG and 1,2 CHD, while sulfate ions do not protect (1). In the present paper it is shown that at pH 6.5 and 7 both sulfate ions and chloride ions protect the transport system. The protection increases with increasing concentration of the two substrate ions.
摘要
精氨酸特异性试剂苯乙二醛和1,2 -环己二酮对阴离子转运的抑制作用取决于介质的pH值和阴离子浓度。在pH 8.0时，氯离子可保护转运系统免受苯乙二醛（PG）和1,2 -环己二酮（1,2 CHD）的抑制，而硫酸根离子则无保护作用（1）。本文表明，在pH 6.5和7时，硫酸根离子和氯离子均可保护转运系统。随着两种底物离子浓度的增加，保护作用增强。
