Polycationic peptides from diatom biosilica that direct silica nanosphere formation.
Diatom cell walls are regarded as a paradigm for controlled production of nanostructured silica, but the mechanisms allowing biosilicification to proceed at ambient temperature at high rates have remained enigmatic. A set of polycationic peptides (called silaffins) isolated from diatom cell walls were shown to generate networks of silica nanospheres within seconds when added to a solution of si...
متن کاملMining the diatom genome for the mechanism of biosilicification.
E ver since the invention of the microscope, scientists and laypeople alike have marveled at the intricate patterning of the silica within the diatom cell wall, termed the frustule (Fig. 1). There are well over 10,000 species of diatoms in marine and freshwaters, and each species has a unique wall morphology (1). Although organisms from multiple kingdoms of life produce siliceous structures (e....
متن کاملSynthesis of a peptide derivative of microcin J25 and evaluation of antibacterial and biological activities
Microcin J25 (MccJ25) is a small ribosomally synthesized antimicrobial peptide that is produced by Enterobacteriacea family especially E.coli. The present study focuses on preparation and evaluation of in vitro antimicrobial and biological properties of a new peptide derived from MccJ25. We prepared a MccJ25-derived peptide containing 14 amino acids and a single intra-molecular disulfide bond a...

متن کاملGnidilatimonoein from Daphne mucronata inhibits DNA synthesis in human cancer cell lines
The anticancer agents from plant sources usually exert their action through a wide range of mechanisms. As part of our studies of plants for new anticancer agents with emphasis on Thymelaeaceae family, we examined the cytotoxicity and anti-tumor activity of the water extract of D. mucronata leaves against induced breast tumor in rats. In the current study, we were interested to obtain some know...
