More | the starch-binding domain (SBD) of glucoamylase from Aspergillus niger is a small globular protein containing a disulfide bond. The structure of the SBD has been determined by NMR. Cys509 and Cys604 are at the N- and C-termini, respectively, and they are linked by a disulfide bond, analysis of the conformation surrounding the disulfide bond, overview | Aspergillus niger |
