Differential expression of notable genes altered in hemA mutant or wild-type bacteria in response to CORM-3 or iCORM-3. The colour-scale bar shows mean fold changes in individual genes of the hemA mutant of E. coli and the corresponding wild-type grown anaerobically in a defined medium after the addition of 100 μM CORM-3 or, for the mutant only, 100 μM iCORM-3. Unless otherwise stated, p values were ≤ 0.05; * indicates a p value that exceeds 0.05.
