In spite of the progress in the treatment of lysosomal storage diseases (LSDs), in some of these disorders the available therapies show limited efficacy and a need exists to identify novel therapeutic strategies. We studied the combination of enzyme replacement and enzyme enhancement by pharmacological chaperones in Pompe disease (PD), a metabolic myopathy caused by the deficiency of the lysoso...
Recombinant Chlamydomonas reinhardtii chlorophyllase 1 (CrCLH1) that could catalyze chlorophyll hydrolysis to chlorophyllide and phytol in vitro was successfully expressed in Escherichia coli. The recombinant CrCLH1 was immobilized through covalent binding with a cubic (3-aminopropyl) triethoxysilane (APTES) coating on magnetic iron oxide nanoparticles (MIONPs), which led to markedly improved e...
we expressed and purified a recombinant p. pyralis luciferase with n-terminal his-tags. the silanized ni or cu-loaded magnetic particles were prepared and used to assemble the his-tagged p. pyralis luciferase. this enzyme immobilized on functionalized magnetic nanoparticles (mnps) via electrostatic interactions of his-tag with ni2+/cu2+ ions on the surface of mnps using simple one step method. ...
CO2 emissions are the primary reason for global warming; hence, biological and chemical technologies converting into useful compounds being actively studied. Biological methods using enzymes can convert under mild conditions. Formate dehydrogenase (FDH) is a representative conversion enzyme. Its function was revealed after isolation from bacteria, yeast, plants. In this study, we evaluated pote...
proline dehydrogenase (prodh; 1.5.99.8) belongs to superfamily of amino acid dehydrogenase, which plays a significant role in the metabolic pathway from proline to glutamate. the goal of this research was gene cloning and characterization of prodh enzyme from pseudomonas fluorescens pf-5 strain. the gene encoding prodh was isolated by means of pcr amplification and cloned in an iptg inducible t...
expressions of recombinant proteins for different applications are important objectives in molecular biotechnology; however, expression of some recombinant proteins is difficult. several methods have been designed for expression of these proteins. the aim of this study was to construct a vector containing mtb32c fragment of mycobacterium tuberculosis (m.tuberculosis) as a fusion partner in orde...
objective(s): streptococcus pyogenes produces extracellular hyaluronidase enzyme. this enzyme is directly associated with the spread of the organism during infection. the objective of the present study was to clone and express the nucleotide sequence of the enzyme which is involved in hyaluronidase enzymatic activity. materials and methods: the enzymatic region of hyaluronidase gene was detecte...
Phosphorylation is a reversible, enzyme-controlled posttranslational process affecting approximately one-third of all proteins in eukaryotic cells at any given time. Any deviation the degree and/or site phosphorylation leads to an abnormal conformation proteins, resulting decline or loss their function. Knowledge phosphorylation-related pathways essential for understanding disease pathogenesis ...
BACKGROUND The ascomycete Ophiostoma piceae produces a sterol esterase (OPE) with high affinity towards p-nitrophenol, glycerol and sterol esters. Its hydrolytic activity on natural mixtures of triglycerides and sterol esters has been proposed for pitch biocontrol in paper industry since these compounds produce important economic losses during paper pulp manufacture. RESULTS Recently, this en...
Background: Botulinum neurotoxin (BoNT) complexes consist of neurotoxin and neurotoxin-associated proteins. Hemagglutinin-33 (HA-33) is a member of BoNT type A (BoNT/A) complex. Considering the protective role of HA-33 in preservation of BoNT/A in gastrointestinal harsh conditions and also its adjuvant role, recombinant production of this protein is favorable. Thus in this study, HA-33 was expr...
