The insufficient supply of heme limits the whole-cell P450 biocatalytic activity.A gene coding for glutamyl-tRNA reductase (GluTR),Glutamyl-tRNA reductase catalyzes the first step of porphyrin biosynthesis.A gene coding for porphobilinogen deaminase (PBGD) The enzyme works by stepwise addition of pyrrolylmethyl groups until a hexapyrrole is present at the active center. The terminal tetrapyrrole is then hydrolyzed to yield the product, leaving a cysteine-bound dipyrrole on which assembly continues. H2O + 4 porphobilinogen <=> hydroxymethylbilane + 4 NH4(+)
