This study aimed to assess the association of single nucleotide polymorphism (SNP) TEX15 rs323347 with male infertile individuals in a Vietnamese cohort and further analyze the haplotypes of TEX15 rs323346 and TEX15 rs323347. A total of 401 unrelated males, including 202 male infertility patients and 199 healthy controls were genotyped for TEX15 rs323347 using polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP).

The structures and stabilities of recombinant chickenmuscle troponin I (TnI) and T (TnT) were investigated by a com-bination of bis-ANS binding and equilibrium unfolding studies.Unlike most folded proteins, isolated TnI and TnT bind the hydrophobic fluorescent probe bis-ANS, indicating the existence of solvent-exposed hydrophobic domains in their structures.

We have studied the reaction native«denatured for the 33-kDa protein isolated from photosystem II. Sucrose and glycerol have profound effects on pressure-induced unfolding. The additives shift the equilibrium to the left; they also cause a significant decrease in the standard volume change (DV). The change in DVwas related to the sucrose and glycerol concentrations.

The phosphoproteins HPrSerP and CrhP are the main effectors for CcpA-mediated carbon catabolite regulation (CCR) inBacillus subtilis. Complexes of CcpA with HPrSerP or CrhP regulate genes by binding to the catabolite responsive elements (cre). We present a quantitative analysis of HPrSerP and CrhP interaction with CcpA by surface plasmon resonance (SPR) revealing small and similar equilibrium constants of 4.8 ± 0.4 lm for HPrSerP–CcpA and 19.1 ± 2.5 lmfor CrhP–CcpA complex dissoci-ation.

NMR and visible spectroscopy coupled to redox measurements were used to determine the equilibrium thermodynamic properties of the four haems in cytochrome c3 under conditions in which the protein was bound to lig-ands, the small anion phosphate and the protein rubredoxin with the iron in the active site replaced by zinc.

HIV gp41(24–157) unfolds cooperatively over the pH range of 1.0–4.0 withTmvalues of 100
C. At pH 2.8, protein unfolding was 80% reversible and theDHvH /DHcal ratio of 3.7 is indicative of gp41 being trimeric. No evidence for a monomer–trimer equilibrium in the concentration range of 0.3–36lMwas obtained by DSC and tryptophan fluores-cence. Glycosylation of gp41 was found to have only a marginal impact on the thermal stability. Reduction of the disulfide bond or mutation of both cysteine residues had only a marginal impact on protein stability. ...

The 3¢-processing of viral DNA extremities is the first step in the integra-tion process catalysed by human immunodeficiency virus (HIV)-1 integrase (IN). This reaction is relatively inefficient and processed DNAs are usually detectedin vitro under conditions of excess enzyme. Despite such experi-mental conditions, steady-state Michaelis–Menten formalism is often applied to calculate characteristic equilibrium⁄kinetic constants of IN.

Thein vivo ligand-binding function and ligand-binding activity of the Dro-sophila melanogaster retinoid-X receptor (RXR) ortholog, ultraspiracle, toward natural farnesoid products of the ring gland were assessed. Using an equilibrium fluorescence-binding assay, farnesoid products in the juven-ile hormone (JH) biosynthesis pathway, and their epoxy derivatives, were measured for their affinity constant for ultraspiracle (USP).

This study on human cytochrome P450 reductase (CPR) presents a com-prehensive analysis of the thermodynamic and kinetic effects of pH and solvent on two- and four-electron reduction in this diflavin enzyme. pH-dependent redox potentiometry revealed that the thermodynamic equilibrium between various two-electron reduced enzyme species (FMNH • ,FADH • ; FMN,FADH2; FMNH2 ,FAD) is independent of pH.

The well-characterized self-association of a mammalian low-molecular-weight protein tyrosine phosphatase (lmwPTP) produces inactive oligomers that are in equilibrium with active monomers. A role of the inactive oligo-mers as supramolecular proenzymes has been suggested.

Calcium phosphate nanoclusters are equilibrium particles of defined chemi-cal composition in which a core of amorphous calcium phosphate is sequestered within a shell of casein phosphopeptides. Sequence analyses and a structure prediction method were applied to secreted phosphopro-teins of known importance in controlling calcification, and eight noncasein phosphoproteins were identified as containing one or more subsequences capable of forming nanoclusters.

The concentrations and charge strength of "spectator“ or non-reacting electrolytes The tendency to form precipitates will be decreased with increasing ionic strength 1) interactions (but not necessarily reactions) of the reactant species with other charged species 2) interactions of the charged product species with the spectator ions. H2O + H2CO3 H3O+ + HCO3Ka1 increases with increasing ionic strength, so the solution becomes more acidic.

The aim of the study was to investigate the crystallization kinetics and solidification behaviour of Fe60Co8Mo5Zr10W2B15 bulk glass forming alloy. The solidification behaviour in near-equilibrium and non-equilibrium cooling conditions was studied. The eutectic and peritectic reactions were found to exist in the solidification sequence of the alloy. The bulk metallic glass formation was achieved by using two methods: quenching from the liquid state and quenching from the semi-state.

The solubility of a partially soluble salt is decreased when a common ion is added. Consider the equilibrium established when acetic acid, HC2H3O2, is added to water. At equilibrium H+ and C2H3O2- are constantly moving into and out of solution, but the concentrations of ions is constant and equal. If a common ion is added, e.g. C2H3O2- from NaC2H3O2 (which is a strong electrolyte) then [C2H3O2-] increases and the system is no longer at equilibrium. So, [H+] must decrease.
