Biosynthesis of Vitamin B6 inRhizobium
The biosynthetic pathway of pyridoxol (vitamin B6) in Rhizobium was clarified by studies on the incorporation of 13C- or 15N-labeled precursors into pyridoxol or its biosynthetic intermediates. Pyridoxol was formed by ring closure of two compounds, 1-deoxy-d-xylulose and 4-hydroxy-l-threonine. The f...

| Zusammenfassung: | The biosynthetic pathway of pyridoxol (vitamin B6) in Rhizobium was clarified by studies on the incorporation of 13C- or 15N-labeled precursors into pyridoxol or its biosynthetic intermediates. Pyridoxol was formed by ring closure of two compounds, 1-deoxy-d-xylulose and 4-hydroxy-l-threonine. The former was formed from d-glyceraldehyde and pyruvate through decarboxylation of pyruvate, and the latter from glycine and glycolaldehyde. |
