Cocrystallization nke lysyl-tRNA synthetase sitere na Thermus thermophilus na cognate tRNAlys yana yana Escherichia coli tRNAlys.
Lysyl-tRNA synthetase sitere na Thermus thermophilus ka ejirila cognate tRNAlys ma ọ bụ Escherichia coli tRNAlys na-eji ammonium sulfate dị ka mmiri ozuzo.Kristal na-eto site na ngwọta nwere 1: 2.5 stoichiometry nke synthetase dimer na tRNA na 18-22% ammonium sulfate na 50 mM Tris-maleate buffer na pH 7.5.Ogwu abụọ a na-etolite prismatic square, kristal tetragonal nwere oke sel otu yiri nke ahụ (a = b = 233 A, c = 119 A) ma gbasaa ma ọ dịkarịa ala 2.7 A mkpebi.Agbanyeghị, homocomplex bụ nke otu oghere P42 (1) 2 yana heterocomplex nke otu oghere I422.
