Bacterial ferrochelatase turns human: Tyr13 determines the apparent metal specificity of Bacillus subtilis ferrochelatase [PDF]

open access: yes, 2010
Ferrochelatase catalyzes the insertion of Fe(2+) into protoporphyrin IX. The enzymatic product heme (protoheme IX) is a well-known cofactor in a wide range of proteins.

Barley Plants Overexpressing Ferrochelatases (HvFC1 and HvFC2) Show Improved Photosynthetic Rates and Have Reduced Photo-Oxidative Damage under Drought Stress than Non-Transgenic Controls

open access: yesAgronomy, 2020
We investigated the roles of two Ferrochelatases (FCs), which encode the terminal enzyme for heme biosynthesis, in drought and oxidative stress tolerance in model cereal plant barley (Hordeum vulgare).

Ferrochelatase activity of plant frataxin [PDF]

open access: yesBiochimie, 2019
Frataxin plays a key role in cellular iron homeostasis of different organisms. It is engaged in several activities at the FeS cluster assembly machinery and it is also involved in heme biosynthesis. In plants, two genes encoding ferrochelatases (FC1 and FC2) catalyze the incorporation of iron into protoporphyrin IX in the last stage of heme synthesis ...

Methotrexate enhances 5-aminolevulinic acid-mediated photodynamic therapy-induced killing of human SCC4 cells by upregulation of coproporphyrinogen oxidase

open access: yesJournal of the Formosan Medical Association, 2014
Topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) is effective for treatment of oral precancerous and cancerous lesions. This in vitro study tried to examine whether the SCC4 cell killing by ALA-PDT was enhanced by pretreatment of ...

Altering Tetrapyrrole Biosynthesis by Overexpressing Ferrochelatases (Fc1 and Fc2) Improves Photosynthetic Efficiency in Transgenic Barley

open access: yesAgronomy, 2020
Ferrochelatase (FC) is the terminal enzyme of heme biosynthesis. In photosynthetic organisms studied so far, there is evidence for two FC isoforms, which are encoded by two genes (FC1 and FC2).

Mitochondrial contact site and cristae organizing system (MICOS) machinery supports heme biosynthesis by enabling optimal performance of ferrochelatase

open access: yesRedox Biology, 2021
Heme is an essential cofactor required for a plethora of cellular processes in eukaryotes. In metazoans the heme biosynthetic pathway is typically partitioned between the cytosol and mitochondria, with the first and final steps taking place in the ...

Ferrochelatase of Rhodopseudomonas spheroides [PDF]

open access: yesBiochemical Journal, 1970
Extracts of Rhodopseudomonas spheroides contain two ferrochelatases: one is soluble and forms metalloporphyrins from deuteroporphyrin and haematoporphyrin; the other is particulate and forms metalloporphyrins from protoporphyrin, mesoporphyrin, deuteroporphyrin and haematoporphyrin.

Diagnosis and treatment of icteric hepatitis caused by erythropoietic protoporphyria: A case report

open access: yesLiver Research, 2022
Erythropoietic protoporphyria (EPP) is a rare inherited disease caused by partial deficiency activity of the enzyme ferrochelatase (FECH), resulting in excessive accumulation of protoporphyrin IX in erythrocyte and tissues. Here, we report a patient with

Ferrochelatase of spinach chloroplasts [PDF]

open access: yesBiochemical Journal, 1968
Spinach chloroplasts catalyse the incorporation of Fe2+ into protoporphyrin, mesoporphyrin and deuteroporphyrin to form the corresponding haems. This ferrochelatase activity was detected by pyridine haemochrome formation with acetone-dried powders of chloroplasts, or from the formation of [59Fe]haems by intact chloroplasts. Decreasing the mitochondrial

Hyperlipidemia and atherosclerosis associated with liver disease in ferrochelatase-deficient mice1

open access: yesJournal of Lipid Research, 2001
Erythropoietic protoporphyria (EPP) is an inherited disorder of heme synthesis caused by deficiency of the mitochondrial enzyme ferrochelatase. EPP in humans is associated with liver disease, hypertriglyceridemia, and a low level of high density ...
