Gamma glutamyl transpeptidase, (GGT) is a ubiquitous protein which plays a central role in glutathione metabolism and has myriad clinical implications. It has been shown to be a virulence factor for pathogenic bacteria, inhibition of which results in reduced colonization potential. However, existing inhibitors are effective but toxic and therefore search is on for novel inhibitors, which makes it imperative to understand the interactions of various inhibitors with the protein in substantial detail. High resolution structures of protein bound to different inhibitors can serve this purpose...

TALipB (33 kDa) is a solvent stable, enantioselective lipase from Trichosporon asahii MSR54. It is cysteine-rich and shows activation in presence of thiol reducing agents. DIANNA server predicted three disulphide bridges C53-C195 (S1), C89-C228 (S2) and C164-C254 (S3) in the enzyme. Selective disruption of disulphide bonds by cysteine to alanine mutations at Cys53 and Cys89 of S1 and S2 bonds resulted in enzyme activation. Mutant mTALipB (S1+S2) showed increase in specific activity by ∼4-fold (834 mM/mg) and improved Vmax of 6...

Chaperones are a diverse class of ubiquitous proteins that assist other cellular proteins in folding correctly and maintaining their native structure. Many different chaperones cooperate to constitute the 'proteostasis' machinery in the cells. It has been proposed earlier that archaeal organisms could be ideal model systems for deciphering the basic functioning of the 'protein folding machinery' in higher eukaryotes. Several chaperone families have been characterized in archaea over the years but mostly one protein at a time, making it difficult to decipher the composition and mechanistics of the protein folding system as a whole...

BACKGROUND: γ-glutamyltranspeptidase (GGT) is a bi-substrate enzyme conserved in all three domains of life. It catalyzes the cleavage and transfer of γ-glutamyl moiety of glutathione to either water (hydrolysis) or substrates like peptides (transpeptidation). GGTs exhibit great variability in their enzyme kinetics although the mechanism of catalysis is conserved. Recently, GGT has been shown to be a virulence factor in microbes like Helicobacter pylori and Bacillus anthracis. In mammalian cells also, GGT inhibition prior to chemotherapy has been shown to sensitize tumors to the therapy...

β-Lactam antibiotics are among the most widely used antibiotics against microbial pathogens. However, enzymatic hydrolysis of these antibiotics by bacterial β-lactamases is increasingly compromising their efficiency. Although new generation β-lactam antibiotics have been developed to combat antibiotic resistance, β-lactamases have also evolved along with the new variants of the substrate. A strong selection pressure from the newer generation of β-lactam antibiotics has resulted in evolution of different families within each class of β-lactamase...

Beta-lactamases are a superfamily of enzymes which degrade the β-lactam class of antibiotics. They are produced endogenously by the bacterial cells, which when exposed to the β-lactam class of antibiotics inactivate them by cleaving the β-lactam ring. Based on the presence or absence of metallic ligand, β-lactamases have been divided into two broad functional classes. β-Lactamases are a constitutively evolving and expanding superfamily of enzymes, which could be further subdivided on the basis of presence/absence of conserved motifs...

UNLABELLED: BACKGROUND; The announcement of the annual Padma awards in January always generates a great deal of interest as well as controversy and, some believe that many good candidates are excluded and many less deserving ones included. We analysed the recipients in the field of medicine to determine whether or not a pattern emerged regarding who were bestowed these honours. We were not able to objectively evaluate whether or not the honours were 'deserved'. METHODS: We obtained and then analysed the list of awardees from newspapers and the official website of the Ministry of Home Affairs...

Congenital anomalies of the male urogenital tract are common. Some lesions like posterior urethral valve or anterior urethral diverticulum tend to present early in infancy and are often easily diagnosed on conventional contrast voiding cystourethrograms. Other conditions like posterior urethral diverticulum or utricle can be relatively asymptomatic and therefore present late in childhood. We present the spectrum of imaging findings of common and uncommon anomalies involving the male urethra. Since the pediatric radiologist is often the first to make the diagnosis, he or she should be well aware of these conditions...

Nitrate and perchlorate salts of 2,4,6-trimethylaniline have been prepared and characterized by X-ray crystallography and gravimetric analyses. Their thermal decomposition has been studied by TG, TG-DSC and ignition/explosion delays. It has been observed that proton transfer from substituted anilinium ion to nitrate and perchlorate ion regenerate amine, HNO(3) and HClO(4) in condensed phase at higher temperature, where oxidation-reduction between amine and acids leads to ignition and explosion. The kinetics of thermal decomposition was evaluated by applying model fitting as well as isoconversional methods...

A novel bacteriophage infecting Escherichia coli was isolated during a large-scale screen for bacteriophages that may be used for therapy of mastitis in cattle. The 77,554-bp genome of the bacteriophage, named phiEco32, was sequenced and annotated, and its virions were characterized by electron microscopy and proteomics. Two phiEco32-encoded proteins that interact with host RNA polymerase were identified. One of them is an ECF family sigma factor that may be responsible for transcription of some viral genes...

The animal egg is a unique quiescent cell, prepackaged with maternal mRNAs and proteins that have functions in early development. Rapid, transient signaling at fertilization alters egg physiology, resulting in Ca(2+) release from the endoplasmic reticulum (ER) and cytoplasmic alkalinization. These events trigger the zygote developmental program through initiation of DNA synthesis and entry into mitosis. Post-translational modifications of maternal proteins are responsible for the spatio-temporal regulation that orchestrates egg activation...

We report the sequence and analysis of the 814-megabase genome of the sea urchin Strongylocentrotus purpuratus, a model for developmental and systems biology. The sequencing strategy combined whole-genome shotgun and bacterial artificial chromosome (BAC) sequences. This use of BAC clones, aided by a pooling strategy, overcame difficulties associated with high heterozygosity of the genome. The genome encodes about 23,300 genes, including many previously thought to be vertebrate innovations or known only outside the deuterostomes...
