“…For H24R_MT1, only an average p K a value can be determined for the three species (H 5 L)Zn 2 to (H 5 L)H –2 Zn 2 , but also here, p K a values below 5 can be assumed for 6–7 ligands (again not considering the carboxylic group). This lowering of the apparent p K a values is in agreement to literature data for Zn II –thiolate coordination. , In the presence of 3 equiv of Zn II , a major difference to the experiments in the presence of Cd II is observed, in particular for WT_MT1 (Figure S4). In presence of 3 equiv of Cd II , the most deprotonated trinuclear species were (H 5 L)H –3 Cd 3 (p K a 6.3) and (H 5 L)H –4 Cd 3 .…”

“…Previous analytical data using flame atomic absorption spectroscopy showed that WT_MT1 binds three Cd II ions and on average 2.4 Zn II ions, and ESI-MS spectra revealed the ability to coordinate up to 3 equiv of both metal ions . Analogously, the H24R_MT1 mutant evaluated here shows bulk binding of 2.90(4) Cd II ions or 3.01(3) Zn II ions.…”

“…Considering that Neclu_MT1 is physiologically a cadmium-specific MT, the role of this harder imidazole ligand is not obvious. Differences in the interaction of the histidine residue in Neclu_MT1 toward Zn II and Cd II have been previously proposed, however, without unambiguous experimental proof . Hence, with this work, we aim to elucidate the role of the histidine residue, particularly by evaluating its acid–base behavior and coordinating properties.…”

Different Behavior of the Histidine Residue toward Cadmium and Zinc in a Cadmium-Specific Metallothionein from an Aquatic Fungus

Metallothioneins (MTs) are a large superfamily of ubiquitous cysteine-rich metalloproteins with main functions in metal ion homeostasis and detoxification. Neclu_MT1 is a metallothionein from the aquatic fungus Heliscus lugdunensis and so far the only known MT that is solely induced by CdII but not by ZnII or copper ions. In addition to eight cysteine residues, Neclu_MT1 also contains a less common single C-terminal histidine residue. To better understand the role of this histidine residue in metal ion binding, for the first time, potentiometric pH titrations are applied, revealing insights into the protonation and metal ion binding processes. Additional studies with absorption and NMR spectroscopy complement the finding that while the histidine residue is not crucial for the overall metal binding capacity, it does serve as a ligand in the ZnII but not in the CdII form of the protein.

Since the panel does not rely on the existing backing wall for stability, it is possible to replace the wall.…”

This paper introduces a method to create a moment-resisting edge connection between two cross-laminated timber (CLT) panels. With this connection, two-way spanning cross-laminated timber slabs can be realised, where the span exceeds the manufacturing and transport-related width of the individual CLT panels. Until now, mostly on-site gluing solutions have been suggested for such connections. In this study, a solution using a timber–concrete–composite (TCC) system is proposed. For this, self-tapping screws are inserted along the edge face of the CLT component, enabling the formation of a lap splice between two adjacent CLT elements. This lap splice is reinforced by additional rebars and filled with concrete. This means that only familiar, easy-to-handle materials are used on-site, and there is no need for adhesives, which can be difficult to apply. To evaluate the load-bearing capacity of the connection, it was subjected to a pure bending load in four-point bending tests, where load-bearing capacities of up to 70% of the characteristic load-bearing capacity of the solid CLT elements were achieved. An analytical approach for a simplified engineering calculation model is introduced to determine the load acting upon the screws. Based on the experimental results, it is shown that the analytical approach is able to adequately represent the load-bearing capacity of the connection. The analytically determined forces on the screws may then be used to carry out further verifications on this connection method.
