Summary myo ‐ inositol ( MI ) is a key sugar alcohol component of various metabolites, e.g. phosphatidylinositol‐based phospholipids that are abundant in animal and plant cells. The seven‐step pathway of MI degradation was previously characterized in various soil bacteria including B acillus subtilis . Through a combination of bioinformatics and experimental techniques we identified a novel variant of the MI catabolic pathway...
