Biochemical and structural studies on ENT proteins have been limi

Biochemical and structural studies on ENT proteins have been limited by their low endogenous expression levels, hydrophobicity and labile nature. To address these issues, we developed an approach whereby tagged mammalian ENT1 protein was over-expressed in mammalian cell lines, confirmed to be functional and isolated by affinity purification to sufficient levels to be analyzed using MALDI-TOF and tandem MS mass spectrometry.

“A canine influenza virus (CIV) strain of avian origin designated A/Canine/Jiangsu/06/2010 (H3N2) was isolated from dogs exhibiting severe respiratory disease in Jiangsu, China. We announce the complete genome sequence of this viral strain and report major findings from the genomic analysis. This sequence will help us understand the molecular characteristics and evolutionary of H3N2 CIV in China.”
“Bv8 is an amphibian peptide belonging to the widely distributed AVIT protein family. The mammalian orthologues of Bv8 were named prokineticin 1 and prokineticin

2. Two G-protein-coupled receptors for Bv8-prokineticins have been identified. The biological activities of Bv8/PK proteins range from angiogenesis and involvement in reproduction and cancer, to neuronal survival and neurogenesis, hypothalamic hormone secretion, circadian rhythm control and immunomodulatory

Selleck Panobinostat processes. Identifying the structural determinants required for receptor binding of Bv8-PKs is mandatory for the design of PKR antagonists, which may be useful in the treatment and prevention of various disease states.

Here we describe a procedure for the production in Pichia pastoris of Bv8 and 3 mutants: W24A-Bv8, in which the tryptophan in position 24 is substituted by alanine, the double mutant M1-W24A-Bv8, that contains an additional methionine at the N-terminus and Bv8-TyrTyr that includes two additional tyrosines these at the C-terminus. The results evidence a relevant role of tryptophan 24 in Bv8-PKRs interaction. (C) 2010 Elsevier Inc. All rights reserved.”
“Enterobacter cancerogenus is widely distributed in nature and is generally recovered from environmental or vegetal sources. In some cases, it has also been associated with human infections. In this study, the complete genomic sequence of virulent E. cancerogenus bacteriophage Enc34 was determined. The Enc34 genome is 60,364 bp in length and contains 80 open reading frames. To our knowledge, this is the first report of a bacteriophage infecting E. cancerogenus.”
“Wheat-embryo cell-free protein expression system allows efficient production of a wide variety of proteins. Homogeneity of the end products is an important characteristic of an advanced cell-free system that will be used in a field of protein science such as structural biology.
