AsGahB, a peptidoglutaminase-asparaginase acting as the main glutaminase in Aspergillus sojae, was previously purified from the cytoplasm of overexpressing strains. Here, we found that specific proteolytic digestion of AsGahB by extracellular proteases of koji molds is similar to that of AsGahA which exists in proteolytic form under solid-state culture.
AsGahB，一种作用于 Aspergillus sojae 中主要谷氨酰胺酶的肽谷氨酰胺酶-天冬酰胺酶，之前是从过表达菌株的细胞质中纯化得到的。在这里，我们发现曲霉菌的细胞外蛋白酶对 AsGahB 的特异性蛋白水解与在固态培养下以蛋白水解形式存在的 AsGahA 相似。
