Zn2+
enzyme possesses a Zn2+ ion located in the putative tRNA acceptor stem-binding domain. The Zn2+ ion is coordinated by three cysteine and a tyrosine ligand
Zn2+
required, tetracoordinated to residues Cys101, Cys103, Cys119 and Tyr115. The zinc ion has a high impact on the enzyme structure and function. Enzyme Glu-Q-RS contain a single zinc-binding site in their putative tRNA acceptor stem-binding domain. Quantification by X-ray fluorescence spectrometry technique. Absence of saturating zinc in solution displays dramatic change in the solubility of the protein
