BACKGROUND
Allergic reactions to tree nuts are often severe and are outgrown in less than 10% of diagnosed patients.
OBJECTIVE
To determine whether treatment of underlying tree nut sensitization will prevent allergic reactions to cross-reacting tree nuts and to determine the effects of single-tree
A protease was purified from bead tree fruit (Melia azedarach L. var. japonica Makino) in four steps, including HPLC gel-filtration. The M(r) of the enzyme, named melain, was estimated to be 25,000 on SDS-PAGE and on HPLC gel filtration. Melain contained a carbohydrate moiety. Using casein as a
Human utilization of the mulberry-silkworm interaction started at least 5,000 years ago and greatly influenced world history through the Silk Road. Complementing the silkworm genome sequence, here we describe the genome of a mulberry species Morus notabilis. In the 330-Mb genome assembly, we
Trypsin is the workhorse protease in mass spectrometry-based proteomics experiments and is used to digest proteins into more readily analyzable peptides. To identify these peptides after mass spectrometric analysis, the actual digestion has to be mimicked as faithfully as possible in silico. In this
BACKGROUND
Diacylglycerol acyltransferases (DGATs) catalyze the final and rate-limiting step of triacylglycerol (TAG) biosynthesis in eukaryotic organisms. Database search has identified at least 59 DGAT1 sequences from 48 organisms, but the expression of any DGAT1 as a full-length protein in E.
Tree frogs produce a variety of skin defensive chemicals against many biotic and abiotic risk factors for their everyday survival. By proteomics or peptidomics and coupling transcriptome analysis with pharmacological testings, 27 peptides or proteins belonging to 9 families, which act mainly as
The members of the family Adenoviridae are widely spread among vertebrate host species and normally cause acute but innocuous infections. Special attention is focused on adenoviruses because of their ability to transform host cells, their possible application in vector technology, and their
Rational drug design is an important step towards effective patient care enabling lead molecule discovery in a relatively faster and inexpensive way. This article describes a variable string length genetic algorithm with domain specific operators for de novo ligand design. The algorithm first mines
The semi-arid Mediterranean region, characterized by long dry periods followed by heavy bursts of rainfall, is particularly prone to soil erosion. The main goal of this study is to evaluate the soil quality under different practices of bio-physical amelioration which involve the soil-plant system
An incomplete picture has emerged of the complex means by which gallbladder motility is controlled under normal and pathophysiological conditions. In the first part of this review an overall account is presented. The mechanisms of cholecystokinin release, its stimulation by dietary factors and
Arabidopsis thaliana SAG12, a senescence-specific gene encoding a cysteine protease, is widely used as a molecular marker for the study of leaf senescence. To date, its potential orthologues have been isolated from several plant species such as Brassica napus and Nicotiana tabacum. However, little
From the venom of Chinese green tree viper (Trimeresurus stejnegeri), three distinct fibrinogenolytic enzymes: stejnefibrase-1, stejnefibrase-2 and stejnefibrase-3, were purified by gel filtration, ion-exchange chromatography and reverse-phase high-performance chromatography (HPLC). SDS-PAGE
Plant growth-promoting rhizobacteria (PGPR) can potentially be used as an alternative strategy to control plant diseases. In this study, strain ST-TJ4 isolated from the rhizosphere soil of a healthy poplar was found to have a strong antifungal activity against 11 phytopathogenic fungi in agriculture
A novel myotropic peptide, polypedatein, was purified and characterized from the skin secretions of the tree frog, Polypedates pingbianensis. Its primary structure, TLLCKYFAIC, was determined by Edman degradation and mass spectrometry. Polypedatein was subjected to bioassays including myotropic,
The serine protease tissue-type plasminogen activator (tPA) is used as a thrombolytic agent in the management of ischemic stroke, but concerns for hemorrhagic conversion greatly limits the number of patients that receive this treatment. It has been suggested that the bleeding complications
