WebbWhen fused to periplasmic PhoA, three affitins inhibited PulD multimerization in vivo and caused loss of function. In two cases, this was likely to be due to dimerization of the affitin by the bound PhoA, as the effect was absent when the affitins were fused to monomeric MalE. In the third case, the MalE and PhoA moieties probably Webb15 juni 2009 · PhoA fusion proteins were induced with 100 μM IPTG and expressed for 60 min at 30°C.
