Positive assay. Growth curves (top) and maximal growth rates (bottom) of K⁺-uptake deficient bacteria as a function of SARS-CoV 3a protein expression, governed by the level of the inducer $\mathsf{\beta }$-d-1-thiogalactopyranoside (IPTG), as indicated. The analyses were performed in triplicates with indicated standard deviations.
