Cavia porcellus	-	The enzyme may be a 3-phytase (EC 3.1.3.8), or a 4-phytase (synonym 6-phytase, EC 3.1.3.26). The product of the hydrolysis of myo-inositol hexakisphosphate to 1D-myo-inositol 1,2,4,5,6-pentakisphosphate or alternatively 1D-myo-inositol 1,2,3,5,6-pentakisphosphate has not been identified.	-
Mesocricetus auratus	-	The enzyme may be a 3-phytase (EC 3.1.3.8), or a 4-phytase (synonym 6-phytase, EC 3.1.3.26). The product of the hydrolysis of myo-inositol hexakisphosphate to 1D-myo-inositol 1,2,4,5,6-pentakisphosphate or alternatively 1D-myo-inositol 1,2,3,5,6-pentakisphosphate has not been identified.	-
Oryctolagus cuniculus	-	The enzyme may be a 3-phytase (EC 3.1.3.8), or a 4-phytase (synonym 6-phytase, EC 3.1.3.26).
