It is shown how reagents of mixed function can react with biphasic kinetics, and a linear inhibition-binding relationship is neither a necessary nor a sufficient condition for the identification of transport sites.

It could be demonstrated that the anion transport protein may exist in two different conformational states, designated cis and trans, and the different susceptibilities of the transfer site to internal and external 4,4' diacetamido-2,2'-stilbene disulfonate are interpreted on the assumption that the conformation of thetransfer site changes during the transition of the transport protein from the cis to the trans conformation.
Proteins in spermathecal gland secretion and spermathecal fluid and the properties of a 29 kDa protein in queens of Apis mellifera
Development of the protein pattern of the gland secretion and spermathecal fluid was identical from pupae until the age of 3 days and the enzymatic activity was only 1/100 compared to TPI of hemolymph.

A study of the sidedness of the action of a number of these sulfonic acids in red cell ghosts revealed that some inhibit only at the outer membrane surface while others, like APMB, inhibit at either surface, suggesting that at least two different types of membrane sites are involved in the control of anion permeability.
Reabsorption of monocarboxylic acids in the proximal tubule of the rat kidney
The data indicate that a main determinant of the specificity of the Na+-dependent aliphatic aromatic monocarboxylic acid reabsorption system in the renal brush border is the electron density at the reaction center.
