α(1-2,3,6)-mannosidase [For Glycan Release] (CAT#: CB-P269-K) Datasheet

Product Type
The alpha mannosidase from Jack Bean cleaves the alpha(1-2,3,6)-linked mannose.

If the non-cleavable core α(1-6) mannose is present on the substrate, the enzyme is usually combined with core α(1-6) mannosidase (catalog number CB-P270-K).
Source: Jack Bean


Alternate Names: α-D-mannosidase, p-nitrophenyl-α-mannosidase, α-D-mannopyranosidase, α mannosidase, exo-α-mannosidase

Specific Activity:>3 U/mg
Activity:>10 U/mL

Molecular weight: two polypeptides of 64,000 and 44,000 daltons

Specificity: All α(1-2,3,6)-linked mannose

Specific Activity Assay:
One unit of α Mannosidase is defined as the amount of enzyme required to hydrolyze 1 µmole of p-nitrophenyl-α-p-mannoside to p-nitrophenol in 1 minute at pH 5.0 and 37°C.
α Mannosidase from Jack Bean cleaves α(1-2,3,6)-linked mannose.
0.6 U / 60 µL; Sufficient for up to 60 reactions.
Glycoproteins and glycopeptides containing N-linked glycans
