Description
N-
acetyl-
D-
galactosaminidase catalyzes the cleavage of N-
acetylglucosamine (GlcNAc), the monomeric unit of the polymer chitin. 4-
Nitrophenyl-
N-
acetyl-
α-
D-
galactosaminide can be used as a chromogenic substrate for N-
acetyl-
D-
galactosaminidase, generating a yellow solution upon cleavage.
Chemical Properties
