Molecular modelling and site-directed mutagenesis provide insight into saccharide pyruvylation by the Paenibacillus alvei CsaB enzyme.

Pyruvylation is a biologically versatile but mechanistically unexplored saccharide modification. 4,6-Ketal pyruvylated N-acetylmannosamine within bacterial secondary cell wall polymers serves as a cell wall anchoring epitope for proteins possessing a terminal S-layer homology domain trimer. The pyruvyltransferase CsaB from Paenibacillus alvei served as a model to investigate the structural basis of the pyruvyltransfer reaction by a combination of molecular modelling and site-directed mutagenesis together with an enzyme assay using phosphoenolpyruvate (PEP; donor) and synthetic β-D-ManNAc-(1 → 4)-α-D-GlcNAc-diphosphoryl-11-phenoxyundecyl (acceptor).

The S-layer homology domains of Paenibacillus alvei surface protein SpaA bind to cell wall polysaccharide through the terminal monosaccharide residue.

Self-assembling (glyco)protein surface layers (S-layers) are ubiquitous prokaryotic cell-surface structures involved in structural maintenance, nutrient diffusion, host adhesion, virulence, and other processes, which makes them appealing targets for therapeutics and biotechnological applications as biosensors or drug delivery systems. However, unlocking this potential requires expanding our understanding of S-layer properties, especially the details of surface-attachment. S-layers of Gram-positive bacteria often are attached through the interaction of S-layer homology (SLH) domain trimers with peptidoglycan-linked secondary cell wall polymers (SCWPs).

Malnutrition at diagnosis in amyotrophic lateral sclerosis (als) and its influence on survival: Using glim criteria.

Background: Malnutrition is a prognostic factor in Amyotrophic Lateral Sclerosis (ALS). Sometimes, this condition is underdiagnosed, and it might influence on disease progression.

Aims: To evaluate a) nutritional status at the beginning of specialized nutritional treatment and b) the influence of initial nutritional status on disease evolution and survival in a group of patients with amyotrophic lateral sclerosis (ALS).

Structural basis of cell wall anchoring by SLH domains in Paenibacillus alvei.

Self-assembling protein surface (S-) layers are common cell envelope structures of prokaryotes and have critical roles from structural maintenance to virulence. S-layers of Gram-positive bacteria are often attached through the interaction of S-layer homology (SLH) domain trimers with peptidoglycan-linked secondary cell wall polymers (SCWPs). Here we present an in-depth characterization of this interaction, with co-crystal structures of the three consecutive SLH domains from the Paenibacillus alvei S-layer protein SpaA with defined SCWP ligands.

Functional Characterization of Enzymatic Steps Involved in Pyruvylation of Bacterial Secondary Cell Wall Polymer Fragments.

Various mechanisms of protein cell surface display have evolved during bacterial evolution. Several Gram-positive bacteria employ S-layer homology (SLH) domain-mediated sorting of cell-surface proteins and concomitantly engage a pyruvylated secondary cell-wall polymer as a cell-wall ligand. Specifically, pyruvate ketal linked to β-D-ManNAc is regarded as an indispensable epitope in this cell-surface display mechanism.

Influence of quercetin on the interaction of gliclazide with human serum albumin - spectroscopic and docking approaches.

Protein-binding interactions are displacement reactions which have been implicated as the causative mechanisms in many drug-drug interactions. Thus, the aim of presented study was to analyse human serum albumin-binding displacement interaction between two ligands, hypoglycaemic drug gliclazide and widely distributed plant flavonoid quercetin. Fluorescence analysis was used in order to investigate the effect of substances on intrinsic fluorescence of human serum albumin (HSA) and to define binding and quenching properties of ligand-albumin complexes in binary and ternary systems, respectively.

Iodine status and thyroid function among Spanish schoolchildren aged 6-7 years: the Tirokid study.

I deficiency is still a worldwide public health problem, with children being especially vulnerable. No nationwide study had been conducted to assess the I status of Spanish children, and thus an observational, multicentre and cross-sectional study was conducted in Spain to assess the I status and thyroid function in schoolchildren aged 6-7 years. The median urinary I (UI) and thyroid-stimulating hormone (TSH) levels in whole blood were used to assess the I status and thyroid function, respectively.

Hypergastrinaemia in Cushing's syndrome: pituitary origin or glucocorticoid-induced?

Objectives: Several reports have shown an increase in serum gastrin levels in patients with Cushing's syndrome (CS). However, the actual origin of this hypergastrinaemia is not known. Two hypotheses have been proposed: concomitant ACTH and gastrin secretion by corticotrophic pituitary adenomas or hypergastrinaemia induced by hypercortisolism.

[The assessment and nutritional support of patients with the acquired immunodeficiency syndrome].

Given the negative effect of malnutrition on the immune function, the possibility must be considered that this also affects the clinical progression of AIDS patients. This study was aimed at assessing the state and nutritional support indicated for patients diagnosed as having AIDS. 114 patients admitted to our hospital in the period 1990-1991 were studied, with assessment of the nutritional state by means of anthropometric parameters (weight, size, tricipital fold, arm muscle circumference), biochemical parameters (albumin, lymphocytes, transferrin, RBP) and the treatment prescribed.
