Extracellular expression of alkaline phytase in Pichia pastoris: Influence of signal peptides, promoters and growth medium
Alkaline phytase isolated from pollen grains of Lilium longiflorum (LlALP) possesses unique catalytic and thermal stability properties that suggest it has the potential to be used as a feed supplement. However, substantial amounts of active enzymes are needed for animal feed studies and endogenous levels of LlALP in lily pollen are too low to provide the required amounts. Active rLlALP2 (coded ...
متن کاملSpecificity of hydrolysis of phytic acid by alkaline phytase from lily pollen.
Phytases are the primary enzymes responsible for the hydrolysis of phytic acid, myo-inositol-1,2,3,4,5,6-hexakisphosphate (I-1,2,3,4,5,6-P6). A number of phytases with varying specificities, properties, and localizations hydrolyze phytic acid present in cells. The specificity of hydrolysis of phytic acid by alkaline phytase from lily (Lilium longiflorum L.) pollen is described. Structures of th...

in the detergent industry. In this study, the extracellular alkaline serine protease gene, aprE, from Bacillusclausii was amplified by PCR and further cloned and expressed in B. subtilis WB600 using the pWB980 expression vector. Protease activity of the recombinant B. subtilis WB600 harboring the plasmid pWB980/aprEreached up to 1020 U/ml, approximately 3-folds higher than the nativ...
متن کاملCloning, Codon Optimization, and Expression of Yersinia intermedia Phytase Gene in E. coli
Background: Phytate is an anti-nutritional factor in plants, which catches the most phosphorus contents and some vital minerals. Therefore, Phytase is added mainly as an additive to the monogastric animals’ foods to hydrolyze phytate and increase absorption of phosphorus. Objectives: Y. intermedia phytase is a new phytase with special characteristics such as high specific activity, pH stabilit...
متن کاملCloning and optimization of phytase enzyme gene expression in Escherichia coli
Introduction Phytase is an enzyme that has the ability to break down phytic acid into myoinositol and mineral phosphate, and widely uses as an additive in animal foods. The aim of this study was to achieve a high level of bacterial phytase expression in PET26b expression host. Materials and Methods To generate the recombinant phytase enzyme, the target gene was introduced into the expression ...
