An engineered variant of MECR reductase reveals indispensability of long-chain acyl-ACPs for mitochondrial respiration

open access: yesNature Communications, 2023
Mitochondrial fatty acid synthesis (mtFAS) is essential for respiratory function. MtFAS generates the octanoic acid precursor for lipoic acid synthesis, but the role of longer fatty acid products has remained unclear.

Differential Effects of Mercurial on the Lipoyl Reductase and Diaphorase Activities of Lipoyl Dehydrogenase

open access: yesJournal of Biological Chemistry, 1966
Abstract The sensitivity of lipoyl dehydrogenase to phenylmercuric acetate, a reagent for —SH groups, has been investigated. Titration of available sulfhydryl groups in the enzyme brings about inactivation in the reduced diphosphopyridine nucleotide-lipoyl reductase activity, while activity with the artificial hydrogen acceptor 2,6-dichloroindophenol ...

Overexpressing the H-protein of the glycine cleavage system increases biomass yield in glasshouse and field grown transgenic tobacco plants [PDF]

open access: yes, 2018
Photorespiration is essential for C3 plants, enabling oxygenic photosynthesis through the scavenging of 2‐phosphoglycolate. Previous studies have demonstrated that overexpression of the L‐ and H‐proteins of the photorespiratory glycine cleavage system ...

Formation of reactive oxygen species by human and bacterial pyruvate and 2- oxoglutarate dehydrogenase multienzyme complexes reconstituted from recombinant components [PDF]

open access: yes, 2015
Individual recombinant components of pyruvate and 2-oxoglutarate dehydrogenase multienzyme complexes (PDHc, OGDHc) of human and Escherichia coli (E. coli) origin were expressed and purified from E. coli with optimized protocols.

Proteomic analysis reveals a novel function of the kinase Sat4p in Saccharomyces cerevisiae mitochondria. [PDF]

open access: yesPLoS ONE, 2014
The Saccharomyces cerevisiae kinase Sat4p has been originally identified as a protein involved in salt tolerance and stabilization of plasma membrane transporters, implicating a cytoplasmic localization. Our study revealed an additional mitochondrial (mt)

The Regulation of Trace Metal Elements in Cancer Ferroptosis. [PDF]

open access: yesAdv Biol (Weinh)
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Clinical and genetic aspects of defects in the mitochondrial iron-sulfur cluster synthesis pathway [PDF]

open access: yes, 2018
Iron-sulfur clusters are evolutionarily conserved biological structures which play an important role as cofactor for multiple enzymes in eukaryotic cells.

Mitochondrial fatty acid synthesis coordinates oxidative metabolism in mammalian mitochondria

open access: yeseLife, 2020
Cells harbor two systems for fatty acid synthesis, one in the cytoplasm (catalyzed by fatty acid synthase, FASN) and one in the mitochondria (mtFAS).

Characterization of Helianthus annuus Lipoic Acid Biosynthesis: The Mitochondrial Octanoyltransferase and Lipoyl Synthase Enzyme System

open access: yesFrontiers in Plant Science, 2021
Lipoic acid (LA, 6,8-dithiooctanoic acid) is a sulfur containing coenzyme essential for the activity of several key enzymes involved in oxidative and single carbon metabolism in most bacteria and eukaryotes. LA is synthetized by the concerted activity of

Mutation of the palmitoylation site of estrogen receptor alpha in vivo reveals tissue-specific roles for membrane versus nuclear actions [PDF]

open access: yes, 2014
Estrogen receptor alpha (ERalpha) activation functions AF-1 and AF-2 classically mediate gene transcription in response to estradiol (E2). A fraction of ERalpha is targeted to plasma membrane and elicits membrane-initiated steroid signaling (MISS), but ...
