The objective of this review was to describe the enzymatic properties of multiple inositol polyphosphate phosphatase (MINPP1/MIPP) as an unusual member of histidine acid phosphatase, distinct from conventional microbial phytases and their additional physiological functions besides degrading phytate. Considering parameters such as pH activity profile, substrate specificity, catalytic efficiency, and stability, MINPP1 is of merit as a novel phytase source for developing an ideal feed additive supported by functional metagenomics fused with recombinant DNA technology and classical protein engineering. In addition, MINPP1 appears to be involved in some biological activities such as cell survival, stress, lipopolysaccharide and inorganic polyphosphate-induced inflammatory response, milk fatty acid composition-related metabolism and bone-related growth and pathophysiology, which can be important for the production performance of farm animals. Future directions need profound studies revealing the direct effects of MINPP1 on these physiological events.
