+## Complementation of R401 ∆pvdy
+
+Complementation of R401 *∆pvdy* was conducted by expressing the coding region of R401 *pvdY* under its putative native promoter from a low-copy plasmid in the *∆pvdy* mutant background. Plasmid construction was conducted using Gibson assembly as described before. In brief, the coding region of R401 *pvdY* was co amplified with a 1.5 kb region upstream of the gene and ligated into a linearized pSEVA22l (18) vector backbone. This vector was integrated into *E. coli* BW29427 cells and subsequently integrated into R401 *∆pvdy via* bi-parental conjugation.
