The discovery of the tumour-inhibitory properties of asparaginase began 50 years ago with the observation that guinea-pig serum-treated lymphoma-bearing mice underwent rapid and often complete regression. Soon afterwards, the asparaginase of bacterial origin was isolated. The asparaginases of bacterial origin

To evaluate the clinical usefulness of serum 1-methyladenosine, several modifications have been made in our previously established inhibition ELISA system. Horseradish peroxidase (HRP) labeled anti-mouse IgG and 3,3',5,5'-tetramethylbenzidine (TMBZ) were used as a secondary antibody and a substrate, respectively. The

Prions are self-propagating conformations of proteins that can cause heritable phenotypic traits. Most yeast prions contain glutamine (Q)/asparagine (N)-rich domains that facilitate the accumulation of the protein into amyloid-like aggregates. Efficient transmission of these infectious aggregates to daughter cells requires

Seasonal influenza A viruses (IAV) originate from pandemic IAV and have undergone changes in antigenic structure, including addition of glycans to the viral hemagglutinin (HA). Glycans on the head of HA promote virus survival by shielding antigenic sites, but highly

Increasing evidence suggests an interaction of oxidative stress and the formation of advanced glycation end products (AGE) in the onset and progression of Alzheimer's disease. We studied levels of pentosidine and N(epsilon)-(carboxymethyl)-lysine (CML) in serum and cerebrospinal fluid (CSF) of

Recently, we reported that several polymorphisms and haplotypes in the choline acetyltransferase gene (ChAT) are associated with nicotine dependence (ND). Of them, SNP rs1880676 is of particular interest because: (1) it is a non-synonymous variant located in the coding region

HIV neutralizing antibodies (nAbs) represent an important tool in view of prophylactic and therapeutic applications for HIV-1 infection. Patients chronically infected by HIV-1 represent a valuable source for nAbs. HIV controllers, including long-term non-progressors (LTNP) and elite controllers (EC), represent

Experimental and clinical studies give evidence for breakdown of membrane phospholipids during neurodegeneration. In the present study, we measured the levels of glycerophosphocholine (GPCh), phosphocholine (PCh), and choline, that is, water-soluble metabolites of phosphatidylcholine (PtdCho), in human cerebrospinal fluid (CSF).

Signal peptide cleavage and N-glycosylation of proteins are co-translational processes, but little is known about their interplay if they compete for adjacent sites. Here we report two unique findings for processing of glycoprotein 3 of equine arteritis virus. Glycoprotein 3

The putative L-haloacid dehalogenase gene (DehRhb) from a marine Rhodobacteraceae family was cloned and overexpressed in Escherichia coli. The DehRhb protein was shown to be an L-haloacid dehalogenase with highest activity towards brominated substrates with short carbon chains (≤ C3).

Escherichia coli expresses two L-asparaginase (EC 3.5.1.1) isozymes: L-asparaginse I, which is a low affinity, cytoplasmic enzyme that is expressed constitutively, and L-asparaginase II, a high affinity periplasmic enzyme that is under complex co-transcriptional regulation by both Fnr and Crp.

The formation of isoaspartate (isoAsp) from asparaginyl or aspartyl residues is a spontaneous post-translational modification of peptides and proteins. Due to isopeptide bond formation, the structure and possibly function of peptides and proteins is altered. IsoAsp modifications within the peptide

Bacillus thuringiensis Cry4Ba toxin is lethal to mosquito-larvae by forming ion-permeable pores in the target midgut cell membrane. Previously, the polarity of Asn(166) located within the α4-α5 loop composing the Cry4Ba pore-forming domain was shown to be crucial for larvicidal

It is widely accepted that ubiquitin-conjugating enzymes contain an active site asparagine that serves as an oxyanion hole, thereby stabilizing a negatively charged transition state intermediate and promoting ubiquitin transfer. Using structural and biochemical approaches to study the role of
