Codon-optimized Carbonic Anhydrase from Dunaliella species: Expression and Characterization

ثبت نشده
چکیده

Carbonic anhydrases (CAs) has been focused as biological catalysis for CO2 sequestration process because it can catalyze the conversion of CO2 to bicarbonate. Here, codon-optimized sequence of α type-CA cloned from Duneliala species. (DsCAopt) was constructed, expressed, and characterized. The expression level in E. coli BL21(DE3) was better for codon-optimized DsCAopt than intact sequence of DsCAopt. DsCAopt enzyme shows high-stability at pH 7.6/10.0. In final, we demonstrated that in the Ca solution, DsCAopt enzyme can catalyze well the conversion of CO2 to CaCO3, as the calcite form. Keywords—Carbonic anhydrase, Codon-optimization, Duneliala species, CO2 sequestration

Partial rescue of human carbonic anhydrase II frameshift mutation by ribosomal frameshift.

A single-base-pair deletion in exon 7 of the human carbonic anhydrase II gene was found to be the molecular defect in a group of independently ascertained, clinically heterogeneous, Hispanic carbonic anhydrase II-deficient patients, all of whom had ancestors from the Caribbean islands. This mutation predicts a +1 frameshift at codon 227 and incorporation of 12 missense amino acids before an ear...

Transcriptional Regulation of the β-Type Carbonic Anhydrase Gene bca by RamA in Corynebacterium glutamicum

Carbonic anhydrase catalyzes the reversible hydration of carbon dioxide to bicarbonate and maintains the balance of CO2/HCO3- in the intracellular environment, specifically for carboxylation/decarboxylation reactions. In Corynebacterium glutamicum, two putative genes, namely the bca (cg2954) and gca (cg0155) genes, coding for β-type and γ-type carbonic anhydrase, respectively, have been identif...

Effect of long-term oral administration of extra thyroxine on oviductal expression of carbonic anhydrase and avidin-related protein-2 genes in broiler breeder hens

Avian sperm are stored in the sperm storage tubules (SSTs) of the hen oviduct for a prolonged period. The impact of avidin-related protein-2 (AVRP2) and carbonic anhydrase II (CA II) in sperm viability in the SSTs has been suggested. The aim of the present study was to investigate the effect of oral administration of a high dose of thyroxine on the oviductal expression of AVRP2<...

An unusual halotolerant alpha-type carbonic anhydrase from the alga Dunaliella salina functionally expressed in Escherichia coli.

A 60-kDa, salt-inducible, internally duplicated alpha-type carbonic anhydrase (Dca) is associated with the plasma membrane of the extremely salt-tolerant, unicellular, green alga Dunaliella salina. Unlike other carbonic anhydrases, Dca remains active over a very broad range of salinities (0-4M NaCl), thus representing a novel type of extremely halotolerant enzyme. To elucidate the structural pr...

Investigation of solvent effect on the active site energy of Carbonic Anhydrase and Ribonucleotide Reductase

Enzymes catalyze many biological reactions. The rates of chemical reaction in the presence ofenzymes are, in some cases, accelerated more than 10 orders of magnitude relative to thecorresponding rates in solution.In this paper a comparison between optimized structures of two enzyme molecules in aspect ofenergy and dipole moment in different conditions including presence of metallic ion, without...
