Heme is synthesized from
WebAbstract In green plants, archaebacteria and many eubacteria, the porphyrin ring that is common to both chlorophyll and heme is synthesized from 5-aminolevulinic acid (ALA) via an interesting pathway. This two-step process involves the unusual enzymes glutamyl-tRNA reductase and glutamate-1-semialdehyde 2,1-aminomutase. WebIn conclusion, we have previously reported that bacterial heme was synthesized by artificial expressions of ALA synthase, NADP-dependent malic enzyme, and dicarboxylic acid …
