At3g55260: HEXO1 (BETA-HEXOSAMINIDASE 1)

Encodes a protein with ��,-hexosaminidase activity (the enzyme is active with p-nitrophenyl-��,-N-acetylglucosaminide as substrate but displayed only a minor activity toward p-nitrophenyl-��,-N-acetylgalactosaminide). The enzyme displays no distinct preference for a specific terminal GlcNAc residue and indeed cleaved the asialoagalactodabsylglycopeptide GnGn to a mixture of products.
