而后锰蛋白转移到细胞外周质，开始对锰原子进行捕获。
The manganese protein is then transported to the periplasm having first trapped its manganese.
结果：8周的胚胎，气管壁由2 3层复层柱状上皮细胞及外周的间充质构成，上皮细胞的PAS反应为阳性。
Result: at 8-week embryo, trachea consists of 2-3 layers of stratified columnar cells and mesenchyme around the cells, the reaction of PAS of epithelium was positive.
大肠杆菌中外源蛋白可定位于胞内、周质或胞外培养基中。
Heterologous proteins could be expressed directly in the cytoplasm, secreted into the periplasmic space or extracellular medium.
由于大量反应是由反应中心位于外周胞质空间的膜结合脱氢酶催化的，所以反应底物不需要转运入细胞内。
As most reactions are catalyzed by the membrane-bound dehydrogenases whose reaction centers locate in the peripheral cytoplasm space, transfer of the substrates into the cell is unnecessary.
