The single-strand-specific S1 nuclease from Aspergillus oryzae is an archetypal enzyme of the S1-P1 family of nucleases with a widespread use for biochemical analyses of nucleic acids. We present the first X-ray structure of this nuclease along with a thorough analysis of the reaction and inhibition mechanisms and of its properties responsible for identification and binding of ligands. Seven st...
Background and Objectives: Cinnamon contains phenolic and non-phenolic bioactive compounds. The aim of this research was investigating the antimicrobial and anti-enzymatic properties of cinnamon (Cinnamomum verum) hydrosol. Materials and Methods: In this laboratory study, chemical composition of cinnamon hydrosol was analyzed by Gas chromatography–mass spectrometry method. Antibacterial effec...
A study was conducted to determine the antibacterial and antifungal activities of Polygonum hydropiper (L.) root extract on chloroform against both bacteria and fungi using the disc diffusion method. The extract showed significant antibacterial activities against four gram-positive (Bacillus subtilis, Bacillus megaterium, Stapphylococcus aureus and Enterobacter aerogenes) and four gram-negative...
At one end of the 70 kb aflatoxin biosynthetic pathway gene cluster in Aspergillus parasiticus and Aspergillus flavus reported earlier, we have cloned a group of four genes that constitute a well-defined gene cluster related to sugar utilization in A. parasiticus: (1) sugR, (2) hxtA, (3) glcA and (4) nadA. No similar well-defined sugar gene cluster has been reported so far in any other related ...
the reproductive range of the iranian population of white tip nematode in rice, aphel-enchoides besseyi, was investigated in vitro to find out a suitable medium as well as a fa-vorable fungal host for monoxenic culturing this nematode. studies were carried out on rice seed associated fungi, pathogenic fungi and one mushroom (agaricus bisporus) grown on three culture media, rpa (rice polish agar...
Aspergillus fumigatus is a filamentous fungal saprophyte that is ubiquitous in the environment. It is also a human pathogen and induces allergenic response, negatively impacting health care and associated costs significantly around the world. Much of the basic biology of this organism is only poorly understood, but the recent completion and publication of its genome sequence provides an excelle...
Xanthorrhizol was isolated from the rhizome of Curcuma xanthorrhiza (Zingiberaceae) and its in vitro activity against opportunistic filamentous fungi was evaluated using the NCCLS (M38-A) standard method. Xanthorrhizol was found to be active against all the species tested, namely Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Fusarium oxysporum, Rhizopus oryzae and Trichophyton m...
A comparative molecular study of Aperigiullus protease using sequence gene representative 25 different Aspergillus species (Aspergillus fumigatus, oryzae, flavus, novofumigatus, viridinutans, pseudotamarii, clavatus, sojae, fischeri, caelatus, campestris, costaricaensis, candidus, neoniger, mulundensis, ibericus, niger, piperis, eucalypticola, vadensis, steynii, and lentulus) have been describe...
