An α-subunit loop structure is required for GM2 activator protein binding by β-hexosaminidase A
The α- and/or β-subunits of human β-hexosaminidase A (αβ) and B (ββ) are ~60% identical. In vivo only β-hexosaminidase A can utilize GM2 ganglioside as a substrate, but requires the GM2 activator protein to bind GM2 ganglioside and then interact with the enzyme, placing the terminal GalNAc residue i...
