Iron-sulfur cluster redox chemistry and dimer dissociation in the outer mitochondrial membrane protein, mitoNEET.
J Biol Inorg Chem
December 2024
Department of Chemistry and Biochemistry, University of Toledo, Toledo, OH, USA.
The outer mitochondrial membrane protein known as mitoNEET was discovered when it was labeled by a photoaffinity derivative of the anti-diabetes medication, pioglitazone. The biological role for mitoNEET and its specific mechanism for achieving this remains an active subject for research. There is accumulating evidence suggesting that mitoNEET could be a component of mitochondrial FeS cofactor biogenesis.

Alanine racemase (Alr) catalyzes the pyridoxal 5'-phosphate (PLP)-dependent racemization between L- and D-alanine in bacteria. Owing to the potential interest in targeting Alr for antibacterial drug development, several studies have determined the structures of Alr from different species, proposing models for the reaction mechanism. Insights into its reaction dynamics may be conducive to a better understanding of the Alr reaction mechanism.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide and a major global health concern. In the United States (US), individuals of Black or African American racial identity experience disproportionately higher rates of TBI and suffer from worse post-injury outcomes. Contemporary research agendas have largely overlooked or excluded Black populations, resulting in the continued marginalization of Black patient populations in TBI studies, thereby limiting the generalizability of ongoing research to patients in the US and around the world.

Fish Shellfish Immunol

A number of studies have been demonstrated that arachidonate 5-lipoxygenase (ALOX-5) plays a role in regulating a range of physiological and pathological processes through the catalysis of leukotriene formation from arachidonic acid (ARA). The coding sequence of ALOX-5 from Apostichopus japonicus (Aj-ALOX-5) was successfully amplified, resulting in a 2028 bp ORF sequence that encodes 674 amino acids. A comparison of the amino acid sequence with those of other 5-lipoxygenases revealed that Aj-ALOX-5 has the N-terminal "PLAT domain" and C-terminal "lipoxygenase structural domain" characteristic of this enzyme family.

Department of Comparative Biomedical Sciences, College of Veterinary Medicine, Mississippi State University, Mississippi state, MS, 39762, USA.
The production of lipopolysaccharide (LPS)-free recombinant proteins from culture supernatants is of great interest to biomedical research and industry. Due to the LPS-free cell wall structure and the well-defined secretion factor B (SecB)-dependent secretion pathway, Gram-positive bacteria are a superior alternative to Escherichia coli expression systems. However, the lack of inducible expression systems for high yields has been a bottleneck.
