Multiple Mechanisms Regulate Eukaryotic Cytochrome C Oxidase

Cells, 2021
Cytochrome c oxidase (COX), the rate-limiting enzyme of mitochondrial respiration, is regulated by various mechanisms. Its regulation by ATP (adenosine triphosphate) appears of particular importance, since it evolved early during evolution and is still ...

Binding of adenine nucleotides to mitochondrial membrane [PDF]

FEBS Letters, 1975
It has been reported from different laboratories [l-4] that mitochondria are capable of binding ATP. However the exact magnitude of binding, and the relevance of this process to the mechanism of oxidative phosphorylation are still unknown, due to the extremely low amounts of bound nucleotides, and to some difficulties in carrying out the measurements ...

Absence of Ca2+-induced mitochondrial permeability transition but presence of bongkrekate-sensitive nucleotide exchange in C. crangon and P. serratus. [PDF]

PLoS ONE, 2012
Mitochondria from the embryos of brine shrimp (Artemia franciscana) do not undergo Ca(2+)-induced permeability transition in the presence of a profound Ca(2+) uptake capacity. Furthermore, this crustacean is the only organism known to exhibit bongkrekate-

The anabolic steroid stanozolol is a potent inhibitor of human MutT homolog 1

FEBS Letters, EarlyView.
MutT homolog 1 (MTH1) is a member of the NUDIX superfamily of enzymes and is an anticancer drug target. We show that stanozolol (Stz), an anabolic steroid, is an unexpected nanomolar inhibitor of MTH1. The X‐ray crystal structure of the human MTH1–Stz complex reveals a unique binding scaffold that could be utilized for future inhibitor development ...

Metformin Improves Mitochondrial Respiratory Activity through Activation of AMPK

Cell Reports, 2019
Summary: Impaired mitochondrial respiratory activity contributes to the development of insulin resistance in type 2 diabetes. Metformin, a first-line antidiabetic drug, functions mainly by improving patients’ hyperglycemia and insulin resistance. However,

Allosteric regulation accompanied by oligomeric state changes of Trypanosoma brucei GMP reductase through cystathionine-β-synthase domain

Nature Communications, 2020
Trypanosoma brucei guanosine 5′-monophosphate reductase (TbGMPR) catalyses the conversion of GMP to inosine 5′-monophosphate and contains a cystathionine-β-synthase (CBS) domain. Here the authors combine X-ray crystallography and kinetic measurements and
