Beef heart malic dehydrogenases. VII. Reactivity of sulfhydryl groups and conformation of the supernatant enzyme.
Only 3 of the 6 sulfhydryl groups of native bovine heart supernatant malate dehydrogenase (S-MDH) react with p-mercuribenzoate (PMB) with no loss of enzymatic activity. In addition, prolonged incubation of S-MDH in 2.6 M urea solutions does not significantly alter the catalytic properties of the enzyme. In 2.6 M urea, however, all 6 sulfhydryl groups of the enzyme react with PMB, with attendant...
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 ...

15 صفحه اول"Glycerate dehydrogenase" activity in acute myocardial infarction and myocardial ischemia.
Hydroxypyruvate has been shown to be an alternative substrate for lactate dehydrogenase. The clinical value of this “glycerate dehydrogenase’ has been investigated on 60 patients admitted to the hospital with a provisional diagnosis of myocardial infarction. For comparison, lactate dehyd rogenase, a-hydroxybutyric dehyd rogenase, creatine kinase, aspartate transaminase, and alanine transaminase...
متن کاملSulfhydryl Groups and the Structure of Hemoglobin
1. Addition of 2 moles of mersalyl, mercuric chloride, p-chloromercuribenzoate (PCMB), or methyl mercury hydroxide per mole of hemoglobin greatly reduces heme-heme interactions (n), yet these substances have quite different effects on the oxygen affinity (-log p(50)). Mersalyl and mercuric chloride at this concentration each increase the oxygen affinity, while PCMB and methyl mercury have littl...
