α-N-Acetylgalactosaminidase from Microbial, Recombinant

Cat No.
NATE-0931
Description
α-N-acetylgalactosaminidase (EC 3.2.1.49) is a glycoside hydrolase from bacteria and animals, also known as nagalase. The human gene that codes for this enzyme is NAGA. Mutations in this gene and the deficiency in alpha-N-acetylgalactosaminidase activity have been identified as the cause of Schindler disease.
