Abstract
Artificial dye-coupled assays have been widely adopted as a rapid and convenient method to assess the activity of methanol dehydrogenases (MDH). Lanthanide(Ln)-dependent XoxF-MDHs are able to incorporate different lanthanides (Lns) in their active site. Dye-coupled assays showed that the earlier Lns exhibit a higher enzyme activity than the late Lns. Despite widespread use, there are limitations: oftentimes a pH of 9 and activators are required for the assay. Moreover, Ln-MDH variants are not obtained by isolation from the cells grown with the respective Ln, but by incubation of an apo-MDH with the Ln. Herein, we report the cultivation of Ln-dependent methanotroph Methylacidiphilum fumariolicum SolV with nine different Lns, the isolation of the respective MDHs and the assessment of the enzyme activity using the dye-coupled assay. We compare these results with a protein-coupled assay using its physiological electron acceptor cytochrome cGJ (cyt cGJ ). Depending on the assay, two distinct trends are observed among the Ln series. The specific enzyme activity of La-, Ce- and Pr-MDH, as measured by the protein-coupled assay, exceeds that measured by the dye-coupled assay. This suggests that early Lns also have a positive effect on the interaction between XoxF-MDH and its cyt cGJ thereby increasing functional efficiency.

Abstract
Lanmodulin (LanM) is the first identified macrochelator that has naturally evolved to sequester ions of rare earth elements (REEs) such as Y and all lanthanides, reversibly. This natural protein showed a 106 times better affinity for lanthanide cations than for Ca, which is a naturally abundant and biologically relevant element. Recent experiments have shown that its metal ion binding activity can be further extended to some actinides, like Np, Pu, and Am. For this reason, it was thought that LanM could be adopted for the separation of REE ions and actinides, thus increasing the interest in its potential use for industry-oriented applications. In this work, a systematic study of the affinity of LanM for lanthanides and actinides has been carried out, taking into account all trivalent ions belonging to the 4f (from La to Lu) and 5f (from Ac to Lr) series, starting from their chemistry in solution. On the basis of a recently published nuclear magnetic resonance structure, a model of the LanM-binding site was built and a detailed structural and electronic description of initial aquo- and LanM-metal ion complexes was provided. The obtained binding energies are in agreement with the available experimental data. A possible reason that could explain the origin of the affinity of LanM for these metal ions is also discussed.

Abstract
Both toxic and physiological effects of CO are mostly caused by well described interactions with heme-groups of proteins. Interactions of CO with non-heme proteins have also been unveiled. Besides interaction of CO with mitochondrial heme containing respiratory complexes, a BK channel and the phosphate carrier which do not contain metal cofactors, have been identified as CO targets. However, the molecular mechanisms of interaction with non-metal-containing proteins are not understood. We show in this work the effect of CO on the mitochondrial carnitine carrier (SLC25A20) using CORM-3, a widely recognized CO releasing compound. CO exerts an inhibitory effect at the micromolar concentration on the transport function of the transporter extracted from treated mitochondria. The effect is due to a single Cys residue, C136 as revealed by mass spectrometry analysis. A computational approach predicted the need for vicinal Asp and Lys residues for the C136 carbonylation to occur. These data demonstrate a novel mechanism of interaction of CO with a protein not containing metal atoms and will enable the prediction of CO targets.

Abstract
Because of their use in high technologies like computers, smartphones and renewable energy applications, lanthanides (belonging to the group of rare earth elements) are essential for our daily lives. A range of applications in medicine and biochemical research made use of their photo-physical properties. The discovery of a biological role for lanthanides has boosted research in this new field. Several methanotrophs and methylotrophs are strictly dependent on the presence of lanthanides in the growth medium while others show a regulatory response. After the first demonstration of a lanthanide in the active site of the XoxF-type pyrroloquinoline quinone methanol dehydrogenases, follow-up studies showed the same for other pyrroloquinoline quinone-containing enzymes. In addition, research focused on the effect of lanthanides on regulation of gene expression and uptake mechanism into bacterial cells. This review briefly describes the discovery of the role of lanthanides in biology and focuses on open questions in biological lanthanide research and possible application of lanthanide-containing bacteria and enzymes in recovery of these special elements.

Abstract
![]()
The L-type amino
acid transporter LAT1, involved in many biological
processes including the overexpression of some tumors, is considered
a potential pharmacological target. The 1,2,3-Dithiazole scaffold
was predicted to inhibit LAT1 by the formation of an intermolecular
disulfide bond with the thiolate group of cysteine(s). As a result
of the identification of these irreversible covalent inhibitors, we
decided to deeply investigate the recognition stage and the covalent
interaction, characterizing the chemical structures of the selected
ligands. With the aim to provide new insights into the access of the
ligands to the binding pocket and to reveal the residues involved
in the inhibition, we performed docking, molecular dynamics simulations,
and density functional theory-based investigation of three 1,2,3-dithiazoles
against LAT1. Our computational analysis further highlighted the crucial
role played by water molecules in the inhibition mechanism. The results
here presented are consistent with experimental observations and provide
insights that can be helpful for the rational design of new-to-come
LAT1’s inhibitors.

Abstract
Coupled dinuclear copper oxygen cores (Cu2 O2 ) featured in type III copper proteins (hemocyanin, tyrosinase, catechol oxidase) are vital for O2 transport and substrate oxidation in many organisms. μ-1,2-cis peroxido dicopper cores (C P) have been proposed as key structures in the early stages of O2 binding in these proteins; their reversible isomerization to other Cu2 O2 cores are directly relevant to enzyme function. Despite the relevance of such species to type III copper proteins and the broader interest in the properties and reactivity of bimetallic C P cores in biological and synthetic systems, the properties and reactivity of C P Cu2 O2 species remain largely unexplored. Herein, we report the reversible interconversion of μ-1,2-trans peroxido (T P) and C P dicopper cores. CaII mediates this process by reversible binding at the Cu2 O2 core, highlighting the unique capability for metal-ion binding events to stabilize novel reactive fragments and control O2 activation in biomimetic systems.

Abstract
Understanding the role of metal ions in biology can lead to the development of new catalysts for several industrially important transformations. Lanthanides are the most recent group of metal ions that have been shown to be important in biology, that is, in quinone‐dependent methanol dehydrogenases (MDH). Here we evaluate a literature‐known pyrroloquinoline quinone (PQQ) and 1‐aza‐15‐crown‐5 based ligand platform as scaffold for Ca2+, Ba2+, La3+ and Lu3+ biomimetics of MDH and we evaluate the importance of ligand design, charge, size, counterions and base for the alcohol oxidation reaction using NMR spectroscopy. In addition, we report a new straightforward synthetic route (3 steps instead of 11 and 33 % instead of 0.6 % yield) for biomimetic ligands based on PQQ. We show that when studying biomimetics for MDH, larger metal ions and those with lower charge in this case promote the dehydrogenation reaction more effectively and that this is likely an effect of the ligand design which must be considered when studying biomimetics. To gain more information on the structures and impact of counterions of the complexes, we performed collision induced dissociation (CID) experiments and observe that the nitrates are more tightly bound than the triflates. To resolve the structure of the complexes in the gas phase we combined DFT‐calculations and ion mobility measurements (IMS). Furthermore, we characterized the obtained complexes and reaction mixtures using Electron Paramagnetic Resonance (EPR) spectroscopy and show the presence of a small amount of quinone‐based radical.

Abstract
Lanthanides are relative newcomers to the field of cell biology of metals; their specific incorporation into enzymes was only demonstrated in 2011, with the isolation of a bacterial lanthanide- and pyrroloquinoline quinone-dependent methanol dehydrogenase. Since that discovery, the efforts of many investigators have revealed that lanthanide utilization is widespread in environmentally important bacteria, and parallel efforts have focused on elucidating the molecular details involved in selective recognition and utilization of these metals. In this review, we discuss the particular chemical challenges and advantages associated with biology's use of lanthanides, as well as the currently known lanthano-enzymes and -proteins (the lanthanome). We also review the emerging understanding of the coordination chemistry and biology of lanthanide acquisition, trafficking, and regulatory pathways. These studies have revealed significant parallels with pathways for utilization of other metals in biology. Finally, we discuss some of the many unresolved questions in this burgeoning field and their potentially far-reaching applications.

Abstract
A large number of enzymes need a metal ion to express their catalytic activity. Among the different roles that metal ions can play in the catalytic event, the most common are their ability to orient the substrate correctly for the reaction, to exchange electrons in redox reactions, to stabilize negative charges. In many reactions catalyzed by metal ions, they behave like the proton, essentially as Lewis acids but are often more effective than the proton because they can be present at high concentrations at neutral pH. In an attempt to adapt to drastic environmental conditions, enzymes can take advantage of the presence of many metal species in addition to those defined as native and still be active. In fact, today we know enzymes that contain essential bulk, trace, and ultra-trace elements. In this work, we report theoretical results obtained for three different enzymes each of which contains different metal ions, trying to highlight any differences in their working mechanism as a function of the replacement of the metal center at the active site.
