In the Results section under subheading ‘Posttranslational modification of human GLS2 protein’,


“With regard to posttranslational modifications, LC-MS/MS analysis identified the chymotryptic peptide – KEKKCFPKGVDMMAAL - being modified with acetylhypusine in the fourth lysine residue (K-336 of the whole GLS2 amino acid sequence) (Fig. 6-A).”

In the last paragraph of the Discussion section,


“The hypusine-modified lysine in the GAB primary structure (K-336) is located in an unfolded segment of the protein, a short turn of 9 residues connecting two alpha helices in a sequence highly enriched in polar amino acids (KKCFPKGVD), which strongly suggest that this hypusinated lysine is exposed to the external medium.”
