Popis: 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. Interest in this pathway has increased since it was discovered that a tRNA cofactor was required for the formation of ALA. This tRNA(Glu) is common to the biosyntheses of both porphyrins and proteins.
