Equine Hepatic and Renal Metallothioneins
An improved, simplified, and greatly shortened isolation procedure for metallothionein from tissue extracts using gel filtration (Sephadex G-SO) and DEAE-cellulose chromatography is presented. When isolated by this procedure, the molecular weight of both the liver and kidney metalloproteins is found to be about 6600, as determined by equilibrium centrifugation and gel filtration. The amino acid...
متن کاملDossier Metallothioneins ■ Metallothioneins in the clam Ruditapes decussatus : an overview
The clam R. decussatus is a suspension-feeding bivalve mollusc widely distributed in European and Mediterranean coastal waters. Due to its economic importance it is extensively cultured in many countries, and particularly in Portugal where its production represents > 80 % of total shellfish production. The selection of the clam R. decussatus as a bioindicator was a consequence of its economic i...
متن کاملHyperpolarization in Molluscan Neurons
Recovery from K current inactivation was studied in molluscan neurons using two-microelectrode and internal perfusion voltage clamps . Experiments were designed to study the voltage-dependent delayed outward current (IK) without contamination from other K currents . The amount of recovery from inactivation and the rate ofrecovery increase dramatically when the membrane potential is made more ne...
متن کاملPhysiological and chemical characterization of cyanobacterial metallothioneins.
Techniques have been developed for detection, quantitation, and isolation of bacterial metallothioneins (MTs) from cyanobacterial species. These methods involve differential pulse polarography and reverse-phase high-performance liquid chromatography (HPLC) and have allowed detection of picomole quantities of these high sulfhydryl content proteins. The prokaryotic molecule was found to be induce...
متن کاملMetallothioneins: Emerging Modulators in Immunity and Infection
Metallothioneins (MTs) are a family of metal-binding proteins virtually expressed in all organisms including prokaryotes, lower eukaryotes, invertebrates and mammals. These proteins regulate homeostasis of zinc (Zn) and copper (Cu), mitigate heavy metal poisoning, and alleviate superoxide stress. In recent years, MTs have emerged as an important, yet largely underappreciated, component of the i...
