Figure 1. Radical enzymes, including radical S-adenosylmethionine (rSAM) enzymes, glycyl radical enzymes (GREs), and diiron enzymes, perform various challenging CC bond-forming and bond-breaking reactions that have the potential to be incorporated into engineered metabolic pathways. Examples of such ...
However, for chemical interpretation purposes it is better to analyse the non-orthogonal singly-occupied orbitals since each one will correspond to an atomic localized electron overlapping (making a chemical bond) with another one. To illustrate the importance of a non-zero overlap among the spatial...

have been recast as a subset of a more general class called s-hole bonds, in which the negative partner (typically a lone pair on a Lewis base, such as nitrogen or oxygen) interacts with a region of positive charge on the halogen7– making them somewhat analogous to donor–acceptor ...
The coordination of oxygen with the boron atom enhances the acidity of N-H, making it easily deprotonated by the organic base. This step proceeds through the transition state TS2A with an activation energy of 19.5 kcal mol−1. Subsequently, the resulting INT2A releases a chloride anion to ...
The DFT calculations of the relaxed dissociation curves and the zero-point energy (ZPE) correction were performed with the functional B3LYP for structures1to4, since this functional has been found reliable for predicting the structures of Kubo et al. [1]. For structures5–26, geometries have be...
–Amazon systematically abuses its market power and should be broken up as an antitrust action. –Making a bond callable contractually enables screwing the investor. –Share buybacks signify a crooked corporation and is only legal because of regulatory corruption. ...
However, until now, most of the breakage criterions are based on the study in [46], which utilised the laboratory test condition (low confining pressure; coordination number ≤ 3) for making the breakage criterion. The breakage criterion can be more realistic and reliable once the ballast ...
The bond making and breaking processes are basis of all chemical changes taking place in chemical reactions. Bond dissociation energy (BDE) is the amount of energy absorbed when a chemical bond is broken. An excellent understanding of energies necessary to break a bond and energies released during...
