Metal chelates of glycine and glycine peptides.
Since the advancement by Smith et al. (l-4) of the theory that metal ions are chelated simultaneously to enzyme protein and substrate in various polypeptidases, the nature of metal binding to peptides and proteins has become an important as well as an interesting problem. The chelate structures proposed by Smith (3), and later somewhat revised (5, 6), indicate that the metal is bound, at least ...
متن کاملInteraction of Ferritin With Transition Metal Ions and Chelates
In this thesis, interaction of ferritin with transition metal ions and chelates is studied. First, a simple method for synthesizing gold nanoparticles stabilized by horse spleen apoferritin (HSAF) was reported using NaBH4 or 3-(N-morpholino)propanesulfonic acid (MOPS) as the reducing agent. The average particle diameters were 3.6 and 15.4 nm for NaBH4-reduced and MOPS-reduced Au-HSAF, respectiv...
متن کاملThe inhibition of alanine dehydrogenase by metal chelates of tetracycline.
In a recent, communication (1) we described the purification and properties of a soluble alanine dehydrogenase isolated from cell-free extracts of the H37Ra strain of Mycobacterium tuberculosis. This enzyme catalyzes the diphosphopyridine nucleotidelinked oxidative deamination of L-alanine to pyruvate. During the study of this enzyme it was observed that Terramycinl inhibits the oxidative react...
متن کاملMolecular nanotechnologies of gelatin-immobilization using macrocyclic metal chelates
This article is a review of recent developments in the self-assembled nanostructures based on chelate coordination compounds. Molecular nanotechnologies of self-assembly of 3d-element aza- and thiazametalmacrocyclic complexes that happen in nanoreactors on the basis of metal hexacyanoferrate(II) gelatin-immobilized matrix under their contact with water solutions containing various (N,O,S)-donor...
متن کاملDNA nuclease activity of Rev-coupled transition metal chelates.
Artificial nucleases containing Rev-coupled metal chelates based on combinations of the transition metals Fe(2+), Co(2+), Ni(2+), and Cu(2+) and the chelators DOTA, DTPA, EDTA, NTA, tripeptide GGH, and tetrapeptide KGHK have been tested for DNA nuclease activity. Originally designed to target reactive transition metal chelates (M-chelates) to the HIV-1 Rev response element mRNA, attachment to t...
