Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.

Frataxin homolog, mitochondrial; Promotes the biosynthesis of heme as well as the assembly and repair of iron-sulfur clusters by delivering Fe(2+) to proteins involved in these pathways. May play a role in the protection against iron-catalyzed oxidative stress through its ability to catalyze the oxidation of Fe(2+) to Fe(3+). May be able to store large amounts of the metal in the form of a ferrihydrite mineral by oligomerization. Required for ecdysteroidogenesis in the prothoracic gland which is necessary for larval to pupal transition. Belongs to the frataxin family.

Protoheme IX farnesyltransferase, mitochondrial; Converts protoheme IX and farnesyl diphosphate to heme O. Belongs to the ubiA prenyltransferase family.

Heme oxygenase; Heme oxygenase cleaves the heme ring at the alpha methene bridge to form biliverdin. Biliverdin is subsequently converted to bilirubin by biliverdin reductase.

Cytochrome c heme lyase; Links covalently the heme group to the apoprotein of cytochrome c.

Oxygen-dependent coproporphyrinogen-III oxidase; Involved in the heme biosynthesis. Catalyzes the aerobic oxidative decarboxylation of propionate groups of rings A and B of coproporphyrinogen-III to yield the vinyl groups in protoporphyrinogen- IX (By similarity).

Lethal (3) 02640; Hydroxymethylbilane synthase activity. It is involved in the biological process described with: heme biosynthetic process; peptidyl-pyrromethane cofactor linkage.

Delta-aminolevulinic acid dehydratase; Zinc ion binding; porphobilinogen synthase activity. It is involved in the biological process described with: heme biosynthetic process; Belongs to the ALAD family.

Aminolevulinate synthase (Alas) encodes a mitochondrial enzyme involved in cuticle barrier formation and thought to have a role in Heme biosynthesis; Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family.
