多聚磷酸盐及其在分枝杆菌中的生理功能

Polyphosphate and its physiological function in Mycobacteria-A review

摘要:

结核病仍然是全球性传染病。缩短疗程的新药和新疫苗是控制结核病的关键。研究分枝杆菌的生理功能有助于实现上述目的。多聚磷酸盐在细菌胁迫应答中发挥重要作用。结核分枝杆菌具有两类多聚磷酸盐代谢酶以控制细胞内多聚磷酸盐的动态平衡：多聚磷酸盐激酶和多聚磷酸酸盐水解酶。本文综述多聚磷酸盐在分枝杆菌中的代谢及其生理功能，以期为研究多聚磷酸盐在结核分枝杆菌中的生理功能提供参考。

Abstract:

Tuberculosis is still a global infectious disease. New drugs to shorten the course of treatment and new vaccines are the key points to control tuberculosis. The physiological study of Mycobacteria will contribute to the above-mentioned purposes. Polyphosphate plays an important role in the stress adaptation in bacteria. And there are two classes of enzymes:polyphosphate kinase and exopolyphosphatase involved in the polyphosphate metabolism to control the dynamic equilibrium of polyphosphate level in Mycobacteria. Present paper summarized the progress in metabolism and physiological roles of polyphosphate in Mycobacteria, to provide useful information for studying the physiological function of polyphosphate in Mycobacteria.
