    Abstract In current study the pharmaceutically active herbs was used against coccidiosis, caused by a protozoan: Eimeria, lead to $ 3 billion loss annually. The aqueous and methanolic extracts of whole plants were applied in-vitro to assess sporulation inhibition (spi) assay and calculated the inhibitory concentration (IC50). For in-vivo study 9 groups of 14 day old broiler chicks were infected with Eimeria tenella and three groups were treated different concentrations of methanolic extracts of Verbena officinalis and Polygonum glabrum post infection. The mean weight gain, oocyst count, diarrhea, biochemical tests, hematology, and histopathology of all groups were analyzed. The herbs were characterized by antioxidant assay, phytochemical screening, Fourier transmission and infrared (FT-IR), Ultra Violet-visible (UV–Vis) spectroscopy and Gas chromatography and mass spectroscopy (GC–MS). The GC–MS identified phyto-compounds of V. officinalis were docked with S-Adenosyl methionine (SAM) synthetase. The in-vitro study revealed that V. officinalis and P. glabrum have minimum IC50 of 0.14 and 12 mg/ml respectively. The in-vivo experiment showed that V. officinalis had significantly high anticoccidial potential with significant hematological profile like drug treated controls. The histology of treated chicks also showed recovery in the studied tissues. The antioxidant assay showed that V. officinalis have 4.19U/mg Superoxide dismutase (SOD) and 33.96 µM/mg Glutathione (GSH) quantities. The chemical characterization confirmed the presence of large number of organic compounds, however Flavonoids found only in V. officinalis, which suggests the anticoccidial potential of V. officinalis because flavonoids as antagonist of thiamine (Prinzo, 1999), because it promotes the carbohydrate synthesis required. Strychane, 1-acetyl-20a-hydroxy-16-methylene has best binding of with target protein with lowest binding score (-6.4 Kcal/mol), suggests its anticoccidial potential in poultry.

    Abstract RNase P is an essential enzyme that processes 5' end leader sequence of pre-tRNA to generate mature tRNA. The bacterial RNase Ps contain a RNA subunit and one protein subunit, where the RNA subunit contains the catalytic activity. The protein subunit which lacks any catalytic activity, relaxes the ionic requirements for holoenzyme reaction and is indispensable for pre-tRNA cleavage in vivo. In the current study, we reconstituted the M. tuberculosis RNase P holoenzyme in vitro. We prepared the RNase P protein through two different strategies that differ in the conditions under which the recombinant M. tuberculosis protein, expressed in E. coli was purified. The mycobacterial RNase P protein which was purified under native conditions subsequent to isolation from inclusion bodies and in vitro renaturation, was capable of cleaving pre-tRNA specifically without the requirement of RNase P RNA. However, the preparation that was purified under denaturing conditions and refolded subsequently lacked any inherent pre-tRNA processing activity and cleaved the substrate only as a component of the holoenzyme with the RNA subunit. We found that the two RNase P protein preparations attained alternative conformations and differed with respect to their stability as well.
