Expression of plant proteins in E. coli is frequently unsuccessful, but soluble and functional rice catalase-B can be produced in E. coli when it is co-expressed with the chaperone GroEL/ES. The rice catalase exhibited properties typical for a catalase including the decomposition of H(2)O(2) and inhibition by aminotriazole, a specific inhibitor for plant(More)
Homology modeling of the catalase, CatC cloned and sequenced from rice (Oryza sativa L., cv Ratna an Indica cultivar) has been performed based on the crystal structure of the catalase CatF (PDB code 1m7s) by using the software MODELLER. With the aid of molecular mechanics and molecular dynamics methods, the final model is obtained and is further assessed by(More)
The environmental toxin TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin, dioxin) produces diverse toxic effects including a lethal wasting syndrome whose hallmark is suppressed hepatic gluconeogenesis. All TCDD toxicities require activation of the aryl hydrocarbon receptor (AHR), a ligand-activated transcription factor. Whereas the mechanism for AHR induction of(More)
Catalase plays a central role in plant stress responses but is highly susceptible to photoinhibition. A rice catalase-B protein avoiding photoinhibition was developed by mutagenesis of specific amino acids: Leu-189 to Trp-189 and His-225 to Thr-225 and then recombinantly expressed in E. coli. In addition, the site specific mutation also induced 2–2.5-fold(More)
