Notes

[back to top]


Although EF4 improves translational accuracy, it can not reverse paromomycin-induced errors (Qin, 2006). EF4 is a widely conserved protein, the first four domains are related to EF-G domains I, II, III, and V (Qin, 2006). EF4 overexpression is toxic (Qin 2006). EF4 (LepA) is in the lepAB operon but has no known role in signal peptidase I (LepB) activity.[4]
