Understanding of protease specificity is essential in proteomics strategies to correctly compare peptide fragmentation spectra with spectra predicted from data extracted from sequence databases. Here we evaluate the specificities of two proteolytic enzymes Lys-C and Lys-N, which cleave peptide-bonds at, respectively, the C- and N-terminal side of a lysine residue.

Increasing importance of pharmaceutical plants in the world and the presence of many of these plants in our country, which has one of the richest Flora of the world, suggest the need for comprehensive studies. Research of secondary metabolites of medicinal and essential oily plants from Iran’s dry to super dry deserts is very important. One of the most famous species from “Labiatae” family is D...

The essential oils of two plants of the genus Bunium called the common name "Zireh" in Persian have been analyzed using GC, GC/MS and 13C NMR spectroscopy. The oils were subjected to antibacterial activity tests. The essential oils have been extracted using hydro-distillation method. The Oils were subjected to analytical GC and GC/MS. The components of the oils were identified using GC retentio...

The essential oil was obtained by hexan. The sample oil, which was light yellow in color, was dried over anhydrous sodium sulfate and stored under nitrogen in a sealed vial until required. The oil obtained was analyzed by GC-MS and GC/MS. The components of the oil were identified by comparison of their mass spectra to those of a computer library or with authentic compounds and confirmed by comp...

The objective of this study was the isolation and identificaion of essential oil constituents of Salvia sahendica. The antimicrobial activity of the essential oil was also investigated. The aerial parts of the plant were collected in different phenological stages in 2004 from Sahand Mountain (East Azerbayjan Province, Tabriz). The essential oil of S. sahendica was isolated by hydro-distillation...
