Microorganisms as phytase producers
Microbiology, 2012Replenishing of the stores of inorganic phosphate is among the most urgent environmental problems. In soil, phosphorus within inorganic compounds is mostly (over 80%) present as insoluble, phytic acid-based conglomerates. Phytates are strong chelating agents, binding the cations of bivalent metals, as well as peptides and low-molecular metabolites into

RecombinantPichia pastoris overexpressing bioactive phytase
Science in China Series C: Life Sciences, 1998Phytase genephyA2, whose signal peptide encoding sequence and intron sequence had been removed, was modified. The Arg-encoding codons CGG and CAG inphyA2 were mutated into synonymous codon AGA. The modifiedphyA2 was fused behind a-factor signal sequence under the control ofAOX1 promoter in plasmid pPIC9, then introduced into the hostPichia pastoris by ...

Phytase enzymology, applications, and biotechnology
Biotechnology Letters, 2003Phytases are phosphohydrolases that initiate the step-wise removal of phosphate from phytate. These enzymes have been widely used in animal feeding to improve phosphorus nutrition and to reduce phosphorus pollution of animal waste. The potential of phytases in improving human nutrition of essential trace minerals in plant-derived foods is being ...

Recent Advances in Directed Phytase Evolution and Rational Phytase Engineering
2017Phytases are hydrolytic enzymes that initiate stepwise removal of phosphate from phytate. Phytate is the major phosphorous storage compound in cereal gains, oilseeds, and legumes and is indigestible by monogastric animals such as poultry and swine. Supplementation of phytase in animal feed proved to improve animal nutrition and decrease phosphorous ...

Phytase: Sources, preparation and exploitation
Folia Microbiologica, 1998This review deals with phytase (myo-inositol hexakisphosphate phosphohydrolase) and covers microbiological sources, phytase occurrence in plants and animals, its purification, physico-chemical and molecular properties. Protein engineering of phytase and potential enzyme applications are discussed.
