Phytochemical content, antioxidant and antibacterial properties of Typhonium flagelliforme cultivated via soil and hydroponic methods

open access: yesJSFA reports, EarlyView.
Abstract Background Typhonium flagelliforme is a medicinal herb in the Araceae family, widely distributed in Southeast Asia. This study aimed to evaluate the effects of hydroponic and soil‐based cultivation systems on the phytochemical content and bioactivity of T. flagelliforme. Results Using liquid chromatography‐mass spectrometry (LC‐MS) analysis, 9

5S Ribosomal RNA

Biomacromolecules, 2000
Ribosomes have been visualized in electron micrographs in 1943 but 5S rRNA was discovered 20 years later. The next four decades witnessed big advances in our understanding of the ribosome using biochemical, genetic and low resolution structural approaches.

Ribosomal RNA Synthesis and RNA Polymerase

Nature, 1970
MULTIPLE forms of RNA polymerase activity have been isolated from developing sea-urchin embryos, rat liver nuclei and calf thymus1–3. The molecular basis of this heterogeneity is at present unknown but, whatever its basis, the crucial question seems to be whether different enzymes copy different genes.

Terbium binding to ribosomes and ribosomal RNA

Biochemistry, 1975
Terbium binding to rat liver ribosomes and ribosomal RNA (rRNA) was examined by equilibrium dialysis and fluorescence spectroscopy. Upon binding to ribosomes and rRNA, the enhancement of terbium fluorescence emission at both 488 and 541 nm was dependent only upon the amount of bound terbium and independent of ionic strength.
