novel endo-beta(1,4)-D-glucuronidase activity in Mucor rouxii

Extracts from the fungus Mucor rouxii contain an enzyme activity which can degrade the homopolymeric β(1,4)‐d‐glucuronan (mucoric acid) of the fungal wall. The enzyme can also degrade the homopolymeric glucuronan domains of mucoran, a complex polyuronide of the Mucor wall. The enzyme is active at ne...

Description
Summary:Extracts from the fungus Mucor rouxii contain an enzyme activity which can degrade the homopolymeric β(1,4)‐d‐glucuronan (mucoric acid) of the fungal wall. The enzyme can also degrade the homopolymeric glucuronan domains of mucoran, a complex polyuronide of the Mucor wall. The enzyme is active at neutral pH and has an estimated Mr of 27 500. The major product of digestion is a disaccharide, suggesting an endolytic mechanism.
