Application
4-(Hydroxymercuri)benzoic acid is an organic mercurial compound that reacts via mercury-sulfur affinity with sulfhydryl groups in peptides, proteins and other molecules. PCMB may be used for the determination of sulfhydryl groups in proteins according to Boyer, by atomic absorption[1], and stopped-flow measurements, G. Castronuovo-Lepore et al.[2]. It may be used for specific applications such as probing the active site of an enzyme such as cytochrome C oxidase. 4-(Hydroxymercuri)benzoic acid appeared mistakenly as p-chloromercuriobenzoate [PCMB] in earlier literature.

We developed a sensitive, specific method for the low-molecular-mass thiols cysteine, cysteinylglycine, glutathione, and homocysteine and validated the method for measurement of glutathione in blood. The technique was based on reversed-phase chromatography (RPC) coupled on line with cold vapor generation

The present study investigated the significance of apical transport proteins for ruminal acetate absorption and their interaction with different anions. In anion competition experiments in the washed reticulorumen, chloride disappearance rate (initial concentration, 28 mM) was inhibited by the presence

In this work we compared two plant ureases, jackbean urease (JBU) and embryo-specific soybean urease (SBU) and a bacterial (Bacillus pasteurii) urease, for kinetic parameters and other biological properties described recently for ureases that are independent of the ureolytic activity.
