The gene cro promotes lytic growth of phages through binding of Cro protein dimers to regulatory DNA sites. Most Cro proteins are one-to-one orthologs, yet their sequence, structure and binding site sequences are quite divergent across lambdoid phage

S-tert-Butyl m-terphenyl thioethers have been efficiently synthesized by Suzuki–Miyaura coupling reactions with 2,6-dibromo-S-tert-butylthio benzene. Selective monocoupling could be achieved with o-substituted boronic acids. This facilitated the sy

Relativistic DFT calculations suggest that two organo-cesium complexes studied herein afford large HOMO–LUMO gaps of around 2.4 eV with the PBE xc-functional, which accounts for their stability. Energy decomposition studies suggest these two comple
