alpha-galactosidase  M-CSA #913

alpha-galactosidase is a member of the glycoside hydrolase, family 27 and catalyses the hydrolysis of terminal, non-reducing alpha-D-galactose residues in alpha-D-galactosides, including galactose oligosaccharides, galactomannans and galactolipids such as raffinose, melibiose, and stachyose (in descending order of reactivity).
