The natural product prodigiosin 1, often described as an H+/Cl- symport cotransporter, can transport Cl- across lipid vesicles via an anion exchange (or antiport) mechanism.

The binuclear title complex, [Cu(2)Cl(4)(C(14)H(14)N(2))(2)], is located on a crystallographic inversion centre. The Cu(II) ion is in a distorted square-pyramid coordination environment formed by the bichelating N-heterocyclic ligand, two bridging Cl atoms and one terminal Cl atom. One of the bridging Cu-Cl bonds is significantly longer than the other.

Two systems are involved in the transport and phosphorylation of gluconate in Escherichia coli. GntI, the main system, consists of high and low-affinity gluconate transporters and a thermoresistant gluconokinase for its phosphorylation. The corresponding genes, gntT, gntU and gntK at 76.5 min, are induced by gluconate. GntII, the subsidiary system, includes IdnT and GntV, which duplicate activi...

The title compound, C(10)H(10)Cl(3)N(3), features a delocalized unsaturated N C N C N chain and strong intra-molecular N-H⋯N hydrogen bonding across the chelate ring and also intra-molecular N-H⋯Cl contacts to a CCl(3)-group Cl atom. The only inter-molecular contacts in the lattice are non-classical hydrogen bonds between methyl and CCl(3) groups. The pseudo-six-membered ring is distinctly non-...
