0. These mutations also decrease the sensitivity to metals such as zinc, mercury and cadmium. Modelling studies showed that the residue E270 is located in a three-glutamate motif (269EEE271) at the N-terminal of α-helix-10. The results suggest that at acidic pH, the protonation of E270 carboxylate may extend a turn of the helix at the N-terminal, misaligning the pH-sensor and luciferin phenolate binding site residues S286, I288 and E311. In contrast, the substitution of E270A/G may unwind a turn of the α-helix-10, indirectly
