Effect of Ca2+ on beta-propeller phytases.
Beta-propeller phytases (BPPs) are a special class of enzyme that are mainly isolated from Bacillus and are widely used in animal nutrition, human health and environmental protection. BPPs class exhibits both unique Ca2+-dependent catalytic property and highly strict substrate specificity for the calcium-phytate complex. This review describes the effect of Ca2+ on the catalytic activity, thermal stability, and structural conformation of BPPs.
