Interestingly, the two resulting CPs, [Ag(Py-4-CSS)] <sub>n</sub> 1 and [Ag<sub>2</sub>(Py-4-CSS)(Py-4-CSSS)] <sub>n</sub> 2 (Py-4-CSS = pyridine-4-dithiocarboxylate; Py-4-CSSS = pyridine-4-perthiocarboxylate), show disparate structures due to the varied coordination mode of the pyridine group.
In contrast, when expressed in bacteria, they lackedCSS activity because the N-terminal hydrophobic region appeared to induce protein aggregation; (3) when expressed in Drosophila S2 cells, AaCSS and TcCSS were predominantly localized in the ER, but not in the Golgi.
