uptake of iron into cell suspensions is also inhibited and the activity of several iron-containing enzymes declines in cells exposed to p-aminosalicylic acid during their growth . p-aminosalicylic acid is about 50 times more effective towards a mutant of m. smegmatis which required mycobactin under iron-deficient growth conditions than towards the wild-type parent . p-aminosalicylate is taken up into cells by an active process independent of the salicylate uptake system , possibly by the route used for assimilation of p-aminobenzoate .
