The role of salicylic acid in iron metabolism was examined in two wild-type strains (mc(2)155 and NCIMB 8548) and three mutant strains (mc(2)1292 [lacking exochelin], SM3 [lacking iron-dependent repressor protein IdeR] and S99 [a salicylate-requiring auxotroph derived in this study]) of Mycobacterium smegmatis. Synthesis of salicylate in SM3 was derepressed even in the presence of iron, as was ...
