DESCRIPTION
Supplementary Figure S1. 1 H- 15 N HSQC spectra of 15 N-labeled ZG16p titrated with Man- O - Thr (a), Man- O -peptide (b), Manα1-3Man (c) and Glc 1-3Glc (d). Marked peaks are selected for the calculation of dissociation constants (Figure 4). (a) Man- O -Thr. (b) Mannose- O -peptide. - PowerPoint PPT PresentationTRANSCRIPT
