Detection of proteins by hyphenated techniques with endogenous metal tags and metal chemical labelling.
The absolute and relative quantitation of proteins plays a fundamental role in modern proteomics, as it is the key to understand still unresolved biological questions in medical and pharmaceutical applications. Highly sensitive analytical methods are required to quantify proteins in biological samples and to correlate their concentration levels with several diseases. Enzyme-linked immunosorbent...
متن کاملMetals and Neuronal Metal Binding Proteins Implicated in Alzheimer's Disease
Alzheimer's disease (AD) is the most prevalent age-related dementia affecting millions of people worldwide. Its main pathological hallmark feature is the formation of insoluble protein deposits of amyloid-β and hyperphosphorylated tau protein into extracellular plaques and intracellular neurofibrillary tangles, respectively. Many of the mechanistic details of this process remain unknown, but a ...
متن کاملMetal-binding proteins as metal pollution indicators.
The fact that metal-binding proteins are a consequence of elevated metal concentration in organisms is well known. What has been overlooked is that the presence of these proteins provides a unique opportunity to reformulate the criteria of metal pollution. The detoxification effect of metal-binding proteins in animals from polluted areas has been cited, but there have been only very few studies...
متن کاملYeast metallothionein. Sequence and metal-binding properties.
The protein product of the CUP1 locus in Cu-resistant Saccharomyces cerevisiae has been purified and characterized. The protein was found to lack the first 8 amino acids predicted by the nucleotide sequence of the gene. The residues removed from the amino-terminal region include 5 hydrophobic residues, two of which are aromatic. The unique amino terminus starting at Gln9 of the putative DNA tra...
متن کاملMetal-binding proteins and peptides in bioremediation and phytoremediation of heavy metals.
The expression of metal-binding proteins or peptides in microorganisms and plants in order to enhance heavy metal accumulation and/or tolerance has great potential. Several different peptides and proteins have been explored. This review focuses on cadmium (Cd) because of the significant importance of this metal and because of its global presence in many food materials.
