Isolation and Cloning of Phytase Gene from Diverse Sources

Phytases fascinated considerable attention from both scientists and entrepreneurs in the areas of biotechnology. Phytic acid is an anti nutritive component in plant-derived food and feed, and therefore enzymatic hydrolysis of phytic acid is desirable. As the primary sequence is emerging, gene cloning would be the next step to redesign this enzyme for novel substrate specificity; thus, genetic manipulation for this enzyme would lead to better catalytic performance with higher turnover rates and this would be industrially important.
