Abstract
The present invention relates to a recombinant microorganism having an enhanced ability to produce heme, coproporphyrin III (Copro III), and uroporphyrin III (Uro III), and a method for producing heme, coproporphyrin III, and uroporphyrin III using same. When using a recombinant microorganism incorporating a gene that codes glutamyl-tRNA reductase (HemA), glutamate-1-semialdehyde aminotransferase (HemL), and diphtheria toxin repressor (DtxR), which is a transcription factor capable of inducing the expression of genes related to heme metabolic pathways, porphyrin-based structures can be produced at high yield, and thus the method is economic.
