Genetically modified folate overproducing strains of some fungi and bacteria have been constructed, e.g., Ashbya gossypii , Escherichia coli , and Bacillus subtilis , the first being the best folate producer reported to date with folate titers of 6.6 mg/L (i.e., 146-fold higher than the wild strain) 631,632,633,634
The peptide backbone provides three coordination sites for copper: the free alpha-amino group of glycine, the deprotonated amide nitrogen of the glycyl-histidyl bond, and the imidazole nitrogen of the histidine side chain, with the lysine epsilon-amine remaining available for further interactions
