Amino acid composition in T. vaginalis cultured in different iron concentrations. Amino acids detected in IR (closed bars) and ID (open bars) are shown (a). Significance is indicated by asterisks: *P < 0.05; **P < 0.01; ***P < 0.001. b–d Reactions of alanine dehydrogenase, glutamate dehydrogenase, and threonine dehydratase are shown. Relative RNA expression levels (ID/IR) of genes are indicated in red (upregulated in ID) and green (downregulated in ID) colors [5]. IR, iron-rich; ID, iron-deficient
