From: Biosynthesis of catechol melanin from glycerol employing metabolically engineered Escherichia coli
Metabolic pathways related to anthranilate, catechol and melanin biosynthesis in recombinant Escherichia coli W3110 trpD9923. Dashed arrows indicate two or more enzyme reactions. Genes in blue colour were overexpressed from plasmids (aroG fbr, tktA and antABC) or the chromosome (MutmelA). GlpD glycerol transporter, Gly glycerol, Gly3P glyceraldehyde-3-phosphate, G6P glucose-6-phosphate, PPP pentose phosphate pathway, E4P d-erythrose 4-phosphate, PEP phosphoenolpyruvate, DAHP 3-deoxy-d-arabino-heptulosonate 7-phosphate, CHA chorismate, l-Trp l-tryptophan
