  • Title: New pathway for nonphosphorylated degradation of gluconate by Aspergillus niger.
    Author: Elzainy TA, Hassan MM, Allam AM.
    Journal: J Bacteriol; 1973 Apr; 114(1):457-9. PubMed ID: 4698214.
    Abstract:
    A new nonphosphorylative pathway for gluconate degradation was found in extracts of a strain of Aspergillus niger. The findings indicate that gluconate is dehydrated into 2-keto-3-deoxy-gluconate (KDG), which then is cleaved into glyceraldehyde and pyruvate. 6-Phosphogluconate was not degraded under the same conditions. In addition, KDG was formed from glyceraldehyde and pyruvate. Very weak activity was obtained when glyceraldehyde 3-phosphate replaced glyceraldehyde in this reaction.
