Abstract

The importance of cyclic di-GMP (c-di-GMP) and its control of biofilm matrix assembly and production has been a focal point of researchers in recent history. In this issue, Cooley et al. (Cooley RB, Smith TJ, Leung W, Tierney V, Borlee BR, O'Toole GA, Sondermann H, J Bacteriol 198:66-77, http://dx.doi.org/10.1128/JB.00369-15) demonstrate that two c-di-GMP controlled features of Pseudomonas aeruginosa, the periplasmic protease LapG and the surface adhesin CdrA, are linked. CdrA is shown to be a substrate of LapG, with LapG activity controlled by intracellular c-di-GMP levels. This commentary discusses the significance of this finding.

摘要

环二鸟苷酸(c-di-GMP)及其对生物膜基质组装和产生的控制作用的重要性,在最近一直是研究人员关注的焦点。在本期中,库利等人(Cooley RB,Smith TJ,Leung W,Tierney V,Borlee BR,O'Toole GA,Sondermann H,《细菌学杂志》198:66 - 77,http://dx.doi.org/10.1128/JB.00369 - 15)证明,铜绿假单胞菌的两个受c-di-GMP控制的特性,即周质蛋白酶LapG和表面黏附素CdrA,是相互关联的。研究表明CdrA是LapG的底物,LapG的活性受细胞内c-di-GMP水平的控制。本评论讨论了这一发现的意义。
