Rhamnogalacturonan acetylesterase with seven N-linked carbohydrate residues distributed at two N-glycosylation sites refined at 1.12 A resolution
Overview
The crystal structure of the glycoprotein rhamnogalacturonan acetylesterase from Aspergillus aculeatus has been refined to a resolution of 1.12 A using synchrotron data collected at 263 K. Both of the two putative N-glycosylation sites at Asn104 and Asn182 are glycosylated and, owing to crystal contacts, the glycan structure at Asn182 is exceptionally well defined in the electron-density maps, showing the six-carbohydrate structure Manalpha1-6(Manalpha1-3)Manalpha1-6Manbeta1-4GlcNAcbeta1-4GlcNAcbeta-Asn18 2. Equivalent carbohydrate residues were restrained to have similar geometries, but were refined without target values. The refined bond lengths and angles were compared with the values obtained from small-molecule studies that form the basis for the dictionaries used for glycoprotein refinement.
