    Abstract D-xylose is the most abundant fermentable pentose, which usually represents an architectural component of the bacterial cell wall. However, its regulatory function and the involved signaling pathway in bacteria remain largely unclear. Here, we show that D-xylose can act as a signaling molecule to regulate the lipid metabolism and affect multiple physiological characteristics in mycobacteria. D-xylose directly interacts with XylR and inhibits its DNA-binding ability, thus blocking XylR-mediated repression. The xylose inhibitor, XylR, plays a global regulatory role and affects the expression of 166 mycobacterial genes that are involved in lipid synthesis and metabolism. Furthermore, we show that the xylose-dependent gene regulation of XylR affects the multiple physiological characteristics of

    Abstract Cyclic di-GMP (c-di-GMP) is a second messenger that promotes biofilm formation in several bacterial species, but the mechanisms are often unclear. Here, we report that c-di-GMP promotes biofilm formation in mycobacteria in a manner dependent on the nucleoid-associated protein Lsr2. We show that c-di-GMP specifically binds to Lsr2 at a ratio of 1:1. Lsr2 upregulates the expression of HadD, a (3R)-hydroxyacyl-ACP dehydratase, thus promoting the synthesis of keto-mycolic acid and biofilm formation. Thus, Lsr2 acts as a c-di-GMP receptor that links the second messenger's function to lipid synthesis and biofilm formation in mycobacteria.
