Catalytic role of traditional enzymes for biosynthesis of biogenic metallic nanoparticles: a mini-review.

摘要: Although the formation mechanism of biogenically metallic nanoparticles is broadly associated to enzyme mediation, major attention has been given role proteins and peptides in oxido-reduction ions leading these nanostructures. Among wide range biomolecules that can act not only as capping agents but also non-enzymatic form nanoparticles, disulphide bridge-containing amino acids particularly stand out. The literature proposes they actively participate process nanoparticles' synthesis, with thiols groups bridge moieties reaction catalytic sites. Similarly, denaturated enzymes containing exposed S-S or S-H are able reduce nanoparticles. This mini-review focused on biogenic synthesis such gold, silver, copper, platinum, palladium, lead selenium, which proteins, peptides, reductases even oxido-reductases catalysts reduction reaction, opening economically ecologically favourable perspectives field.
