Figure 1
The three-dimensional structure of invertase. (a) The overall three-dimensional structure of invertase. Three glycosylation sites could be allocated to invertase on residues Asn116, Asn143 and Asn299 (indicated in red). The glycosylation chains are indicated in orange. The figure was prepared with PyMOL (DeLano, 2002). (b) Schematic diagram of the topology of invertase. β-Strands are depicted by arrows and α-helices by cylinders. Asterisks represent the glycosylation sites. |
