Shows appreciable ligation activity with both suppressor tRNA(Opal) and tRNA(Amber), and reduces ligation activity with tRNA(Cys); when associated with N-420. Shows higher activity than the E418N/E420N mutant with both suppressor tRNA(Opal) and tRNA(Amber), and the activity with tRNA(Opal) and tRNA(Amber) is almost 30% of that of the wild-type SepRS with tRNA(Cys); when associated with N-420 and V-423.

A456 (≠ N317) mutation to G: Decreased aminoacylation, increased misacylation of non-cognate Tyr, increased amino acid misincorporation, ommatidia defects, neurodegeneration, impaired locomotive performance, reduced lifespan, smaller organ size due to reduced cell proliferation and increased ER stress. Similar but stronger phenotypes except that smaller organ size is due primarily to apoptosis; when associated with 'W-158' in beta subunit.
