Lateral view of the area surrounding catalytic cysteine residues of Erv1 and its variants. a Erv1; b Erv1S32A; c Erv1S32T; d different rendering of Erv1 with solvents. The structures were constructed from Erv1 mutant protein of S. cerevisiae (PDB ID: 4E0I) (a–c) and the Erv1 core of S. cerevisiae (PDB ID: 3W4Y) (d) by PyMOL software. Each subunit was separately rendered in green and pink. Oxygen, nitrogen, and sulfur atoms are rendered in red, blue, and yellow, respectively. The hydrogen bond and water molecule are shown as a black dashed line and cyan sphere, respectively
