DOI: 10.1016/j.cois.2022.100916
Abstract: Ticks are blood-feeding ectoparasites with distinct genomic reductions, inevitably linking them to a parasitic life-style. Ticks have lost the genomic coding and, thus, biochemical capacity to synthesize heme, an essential metabolic cofactor, de novo. Instead,… read more here.

DOI: 10.1016/j.foodchem.2017.06.092
Abstract: Fresh red meat and cured meat consumption increases the risk of gastro-intestinal cancers and it is strongly suspected that nitrosylheme is implicated by stimulating the endogenous production of mutagenic aldehydes and N-nitroso compounds. To investigate… read more here.

DOI: 10.1016/j.foodhyd.2017.07.020
Abstract: Abstract Our work aimed to develop and characterize different alginate beads with either non-heme iron or a blend of heme/non-heme iron. We chose non-heme iron salts such as ferrous sulfate (FS), ferrous ammonium sulfate (FAS),… read more here.

DOI: 10.1016/j.jcat.2021.04.010
Abstract: Abstract Enzymatic N-N bond formation is rare. Herein, the mechanism for the N-nitrosation from Nδ-hydroxy-Nω-hydroxy-Nω-methyl-L-arginine (L-HMA) catalyzed by SznF, a non-heme iron enzyme, has been illustrated, using density functional calculations. The reaction proceeds through the… read more here.

DOI: 10.1016/j.mib.2019.05.006
Abstract: Heme is a bioavailable source of iron, for which different fungi have evolved several distinct acquisition mechanisms. In the iron-scarce animal host, in particular, microbial pathogens are able to utilize the large heme pool of… read more here.

DOI: 10.1021/acs.biochem.9b00044
Abstract: The assignment of biochemical functions to hypothetical proteins is challenged by functional diversification within many protein structural superfamilies. This diversification, which is particularly common for metalloenzymes, renders functional annotations that are founded solely on sequence… read more here.

DOI: 10.1021/acs.inorgchem.8b00187
Abstract: Non-heme iron(II) complexes of pentadentate N4Py (N,N-bis(2-pyridylmethyl)-N-bis(2-pyridyl)methylamine) type ligands undergo visible light-driven oxidation to their iron(III) state in the presence of O2 without ligand degradation. Under mildly basic conditions, however, highly selective base catalyzed ligand… read more here.
