Comparison
of ring conformations of mannopyranose substrates (red) extracted
from cocrystal structures with mannosidases (n =
41), and the inhibitors (n = 50) swainsonine (SWA,
green), deoxymannojirimycin (DMJ, blue), kifunensine (KIF, pink),
noeuromycine (NOY, cyan), and mannoimidazole (MVL, yellow). Presumed
transition states for mannosidases indicated by (*).
