| 3.4.23.18 | additional information | analysis of N-terminal amino acid sequence indicated that the purified enzyme is an acid protease | Aspergillus oryzae |
| 3.4.23.18 | physiological function | the acid protease derived from Aspergillus oryzae causes bifidogenic effect in Sprague-Dawley rats. Bifidobacterium numbers are unaffected by supplementation with purified acid protease (AcP, 0.096 g/kg) at the level equivalent to the AcP amount found in the 1-g/kg Amano protease diet. Bifidobacterium numbers in the cecum and feces, and lactate levels in the cecum are significantly elevated when rats are fed a diet containing 0.384 g/kg AcP (4fold higher amount of AcP than that used in the 1-g/kg Amano protease diet) | Aspergillus oryzae |
