Stimulation of renin secretion by non-diuretic sulfhydryl reagents.
Organomercurial diuretics stimulate renin secretion although the underlying cellular mechanisms remain undefined. Since organomercurials are also known to react with sulfhydryl groups, the present studies determined the effects of sulfhydryl reagents on renin secretion. The effects of the non-diuretic mercurial agent, parachloromercuriphenyl-sulfonate (PCMPS), as well as that of other sulfhydry...
متن کاملSulfhydryl Groups in Proteins
Egg albumin in the native, unaltered state, does not give tests characteristic of sulfhydryl groups. When, however, this protein is treated in any one of several ways, such as by heat (8, 9, 17), ultraviolet irradiation (lo), shaking (lo), or by solution in urea or other amides (7), free sulfhydryl groups make their appearance. The amount of free -SH groups appearing in egg albumin through the ...
متن کاملReaction of Pyridoxamine - Pyruvate Transaminase Sulfhydryl Reagents
Wherever the point has been examined (e.g. References l-6), pyridoxal phosphate enzymes have been found to require free sulfhydryl groups for activity. The functional role played by these groups, however, has not been clear. In glutamate-oxaloacetate transaminase, which has been studied most extensively, no spectrophotometric or enzymatic evidence for their participation in coenzyme binding was...
متن کاملOn the mechanism of enzyme inhibition by sulfhydryl reagents.
In recent years a great deal of evidence has accumulated to show that intact -SH groups are necessary for the full activity of a variety of enzymes. The exact function of the thiol group in the protein part of these “sulfhydryl enzymes,” however, remains obscure. It has been suggested that the -SH group directly participates in the activity of these enzymes, and that it might be actually locate...
متن کاملLocalization of Erythrocyte Membrane Sulfhydryl Groups Essential for Glucose Transport
The reactions of three organic mercurial compounds, chlormerodrin, parachloromercuribenzoate (PCMB), and parachloromercuribenzenesulfonate (PCMBS) with intact red blood cells, hemolyzed red cells, hemoglobin solutions, and hemoglobin-free ghosts have been characterized. Both PCMB and PCMBS react with only 2 to 3 sulfhydryl groups per mole of hemoglobin in solution, whereas chlormerodrin reacts ...
