RidA orthologs from Salmo salar complement a Salmonella enterica ridA mutant. Strains were grown in minimal glycerol (20 mM) medium containing 5 mM serine with 0.2% (wt/vol) L-arabinose. Strains were S. enterica ridA mutant strains carrying the indicated plasmid, including vector only (pCV1), that expressed S. enterica ridA [pCV1-ridA(S. enterica)], S. salar SsRidA-1 (pCV1-SsRidA-1) or SsRidA-2 (pCV1-SsRidA-2). Error bars represent the standard error of the mean (SEM) from three biological replicates of each strain.
