Protein

Beta-mannosidase A

Gene

mndA

Organism
Aspergillus aculeatus
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Exoglycosidase that cleaves the single beta-linked mannose residue from the non-reducing end of beta-mannosidic oligosaccharides of various complexity and length. Involved in the degradation of polymeric mannan and galactomannan. Releases the terminal mannose residue from mannotriose and is somewaht less active on other mannooligosaccharides.1 Publication

Catalytic activityi

Hydrolysis of terminal, non-reducing beta-D-mannose residues in beta-D-mannosides.1 Publication

pH dependencei

Optimum pH is 2.0. Stable from pH 4 to pH 7.1 Publication

Temperature dependencei

Optimum temperature is 70 degrees Celsius.1 Publication
