Artemisinin and Heme [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 2003
A recent Letter to the Editor (R. K. Haynes, D. Monti, D. Taramelli, N. Basilico, S. Parapini, and P. Olliaro, Letter, Antimicrob. Agents Chemother. 47:1175, 2003) presented cogent evidence that artemisinin and its derivatives do not inhibit hemozoin formation in vitro.

Phenotypic continuum of NFU1‐related disorders

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2025-2035, December 2022., 2022
Abstract Bi‐allelic variants in Iron–Sulfur Cluster Scaffold (NFU1) have previously been associated with multiple mitochondrial dysfunctions syndrome 1 (MMDS1) characterized by early‐onset rapidly fatal leukoencephalopathy. We report 19 affected individuals from 10 independent families with ultra‐rare bi‐allelic NFU1 missense variants associated with a

Heme‐hemopexin: A ‘Chronosteric’ heme‐protein [PDF]

open access: yesIUBMB Life, 2007
AbstractHemopexin (HPX) serves as scavenger and transporter of toxic plasma heme to the liver. HPX is formed by two four‐bladed β‐propeller domains, resembling two thick disks that lock together at a 90° angle. The heme is bound between the two β‐propeller domains in a pocket formed by the interdomain linker peptide.

On a class of Hessian type equations on Riemannian manifolds [PDF]

open access: yesProceedings of the American Mathematical Society, 2021, 2022
In this paper, we consider a class of Hessian type equations which include the $(n-1)$ Monge-Amp\`{e}re equation on Riemannian manifolds. The \emph{a priori} $C^2$ estimates and the existence of solutions are established.

Preparative‐Scale Biocatalytic Oxygenation of N‐Heterocycles with a Lyophilized Peroxygenase Catalyst

open access: yesAngewandte Chemie, Volume 135, Issue 5, January 26, 2023., 2023
A lyophilized preparation of an unspecific peroxygenase variant from Agrocybe aegerita (rAaeUPO‐PaDa‐I‐H) is a highly effective catalyst for the oxygenation of a diverse range of N‐heterocyclic compounds. Scalable, high yielding and enantioselective biocatalytic oxygenations have been developed, including 27 preparative examples (ca.

Fabrication of electronically conductive protein-heme nanowires for power harvesting [PDF]

open access: yesSmall, 2024, 2311661, 2023
Electronically conductive protein-based materials could enable the creation of bioelectronic components and devices from sustainable and nontoxic materials, while also being well-suited to interface with biological systems, such as living cells, for biosensor applications.

The Cytochrome P450 OxyA from the Kistamicin Biosynthesis Cyclization Cascade is Highly Sensitive to Oxidative Damage

open access: yesFrontiers in Chemistry, 2022
Cytochrome P450 enzymes (P450s) are a superfamily of monooxygenases that utilize a cysteine thiolate–ligated heme moiety to perform a wide range of demanding oxidative transformations.

NEAr Transporter (NEAT) Domains: Unique Surface Displayed Heme Chaperones That Enable Gram-Positive Bacteria to Capture Heme-Iron From Hemoglobin

open access: yesFrontiers in Microbiology, 2021
Iron is an important micronutrient that is required by bacteria to proliferate and to cause disease. Many bacterial pathogens forage iron from human hemoglobin (Hb) during infections, which contains this metal within heme (iron–protoporphyrin IX ...
