Cysteine desulfurase, mitochondrial is an enzyme that in humans is encoded by the NFS1 gene. [5] [6] [7]
Iron-sulfur clusters are required for the function of many cellular enzymes. The protein encoded by this gene supplies inorganic sulfur to these clusters by removing the sulfur from cysteine, creating alanine in the process. This gene uses alternate in-frame translation initiation sites to generate mitochondrial forms and cytoplasmic/nuclear forms. Selection of the alternative initiation sites is determined by the cytosolic pH. The encoded protein belongs to the class-V family of pyridoxal phosphate-dependent aminotransferases. [7]
Mitochondrial 5-demethoxyubiquinone hydroxylase, also known as coenzyme Q7, hydroxylase, is an enzyme that in humans is encoded by the COQ7 gene. The clk-1 (clock-1) gene encodes this protein that is necessary for ubiquinone biosynthesis in the worm Caenorhabditis elegans and other eukaryotes. The mouse version of the gene is called mclk-1 and the human, fruit fly and yeast homolog COQ7.
NADP-dependent malic enzyme is a protein that in humans is encoded by the ME1 gene.
Folylpolyglutamate synthase, mitochondrial is an enzyme that in humans is encoded by the FPGS gene.
Sulfatase-modifying factor 2 is an enzyme that in humans is encoded by the SUMF2 gene.
MAP kinase-interacting serine/threonine-protein kinase 2 is an enzyme that in humans is encoded by the MKNK2 gene.
NADH dehydrogenase [ubiquinone] iron-sulfur protein 8, mitochondrial also known as NADH-ubiquinone oxidoreductase 23 kDa subunit, Complex I-23kD (CI-23kD), or TYKY subunit is an enzyme that in humans is encoded by the NDUFS8 gene. The NDUFS8 protein is a subunit of NADH dehydrogenase (ubiquinone) also known as Complex I, which is located in the mitochondrial inner membrane and is the largest of the five complexes of the electron transport chain. Mutations in this gene have been associated with Leigh syndrome.
Sulfatase-modifying factor 1 is an enzyme that in humans is encoded by the SUMF1 gene.
MAP kinase-activated protein kinase 5 is an enzyme that in humans is encoded by the MAPKAPK5 gene. The protein encoded by this gene is a member of the serine/threonine kinase family. In response to cellular stress and proinflammatory cytokines, this kinase is activated through its phosphorylation by MAP kinases, including MAPK1/ERK, MAPK14/p38-alpha, and MAPK11/p38-beta. In vitro, this kinase phosphorylates heat shock protein HSP27 at its physiologically relevant sites. Two alternately-spliced transcript variants of this gene encoding distinct isoforms have been reported.
Kynurenine—oxoglutarate transaminase 1 is an enzyme that in humans is encoded by the CCBL1 gene. It is one of the Kynurenine—oxoglutarate transaminases.
NADH dehydrogenase [ubiquinone] 1 alpha subcomplex subunit 5 is an enzyme that in humans is encoded by the NDUFA5 gene. The NDUFA5 protein is a subunit of NADH dehydrogenase (ubiquinone), which is located in the mitochondrial inner membrane and is the largest of the five complexes of the electron transport chain.
Dual specificity protein phosphatase 7 is an enzyme that in humans is encoded by the DUSP7 gene.
39S ribosomal protein L15, mitochondrial is a protein that in humans is encoded by the MRPL15 gene.
MOSC domain-containing protein 2, mitochondrial is a protein that in humans is encoded by the MOSC2 gene.
Probable cytosolic iron-sulfur protein assembly protein CIAO1 is a protein that in humans is encoded by the CIAO1 gene. CIAO1 forms a complex with FAM96B, MMS19, the co-chaperone HSC20 and the scaffold protein ISCU in order to assist iron-sulfur cluster incorporation into cytoplasmic and nuclear iron-sulfur proteins.
NADH dehydrogenase [ubiquinone] 1 alpha subcomplex subunit 8 is an enzyme that in humans is encoded by the NDUFA8 gene. The NDUFA8 protein is a subunit of NADH dehydrogenase (ubiquinone), which is located in the mitochondrial inner membrane and is the largest of the five complexes of the electron transport chain.
Iron-sulfur cluster assembly enzyme ISCU, mitochondrial is a protein that in humans is encoded by the ISCU gene. It encodes an iron-sulfur (Fe-S) cluster scaffold protein involved in [2Fe-2S] and [4Fe-4S] cluster synthesis and maturation. A deficiency of ISCU is associated with a mitochondrial myopathy with lifelong exercise intolerance where only minor exertion causes tachycardia, shortness of breath, muscle weakness and myalgia.
Ubiquitin thioesterase OTUB2 is an enzyme that in humans is encoded by the OTUB2 gene.
Glutaredoxin 5, also known as GLRX5, is a protein which in humans is encoded by the GLRX5 gene located on chromosome 14. This gene encodes a mitochondrial protein, which is evolutionarily conserved. It is involved in the biogenesis of iron- sulfur clusters, which are required for normal iron homeostasis. Mutations in this gene are associated with autosomal recessive pyridoxine-refractory sideroblastic anemia.
Nucleotide-binding protein 2 also known as cytosolic Fe-S cluster assembly factor NUBP2 is a protein that in humans is encoded by the NUBP2 gene.
Aconitase 2, mitochondrial is a protein that in humans is encoded by the ACO2 gene.
