Abstract
PepR1 from Lactobacillus delbrueckii subsp bulgaricus (Lb. bulgaricus) is involved in biosynthesis regulation of the prolidase PepQ. In this paper, we demonstrated that Lb. bulgaricus PepR1 biosynthesis is not constitutive like those of several bacteria but is auto-regulated and depends on the glucose concentration of the culture medium. We propose a model for PepQ regulation by PepR1.
摘要
来自德氏乳杆菌保加利亚亚种（保加利亚乳杆菌）的PepR1参与脯氨酰肽酶PepQ的生物合成调控。在本文中，我们证明保加利亚乳杆菌PepR1的生物合成不像几种细菌那样是组成型的，而是自我调节的，并且取决于培养基中的葡萄糖浓度。我们提出了一个由PepR1调控PepQ的模型。
