1.B.89.1.1









The pore-forming protein, GjpA of 558 aas and up to 9 TMSs in a 1 (N-terminal) + 2 + 2 + 2 + 2 TMS arrangement with a fairly long (~ 120 aas) hydrophilic C-terminal domain.  The channel has an average single-channel conductance of 800 pS in 1 M KCl, is moderately anion-selective, and does not show a voltage dependence for voltages between +100 and -100 mV. GjpA may import and export negatively charged molecules across the outer cell envelope (Jiménez-Galisteo et al. 2017).
