来自热微生物的柚苷酶(鼠李糖苷酶A) Naringinase (Rhamnosidase A) from Thermomicrobia sp.

A thermostable Alpha-L-Rhamnosidase (Naringinase, RhamA) that catalyzes the cleavage of the bond between terminal L(+)-rhamnose and the aglycone of rhamnose-containing glycosides. The enzyme is very active on naringin but has also substantial activity with hesperidin as substrate.   

Available as 100 units.

Enzyme activity: Rham142 Rhamnosidase A (naringinase, alpha-L-rhamnosidase)  catalyzes the cleavage of the bond between terminal L(+)-rhamnose and the aglycone of rhamnose-containing glycosides. Hydrolysis of terminal non-reducing α-L-rhamnose residues in α-L-rhamnosides: naringin, hesperidin and rutin

Activity determination: Rhaminosidase activity was routinely determined in a 100mM KPO4 pH 7.5 buffer for 10 minutes with 2.0mM  final conc. of p-nitro-phenyl-α-L-rhamnopyranoside.

Unit definition: One unit (U) of enzyme activity is the amount that leads to the release of 1 µmol of p-nitro-phenyl-α-L-rhamnopyranoside (pnpR)  per minute

Synonyms: glycoside hydrolase; RhamA; naringinase; hesperidinase; α-L-rhamnosidase A; α-L-rhamnosidase N; α-L-rhamnoside rhamnohydrolase
