Obsoletion request: GO:0016231 & GO:0102148

Please provide as much information as you can:

GO term ID and Label GO:0016231 beta-N-acetylglucosaminidase activity (21 EXP annotations) GO:0102148 N-acetyl-beta-D-galactosaminidase activity (no EXP annotations)
Reason for deprecation Put an x in the appropriate box:
- [x] The reason for obsoletion is that it more specific than the specificity of any known gene product.
"Replace by" term (ID and label) GO:0004563 beta-N-acetylhexosaminidase activity
Are there mappings and cross references to this term? (InterPro, Keywords; check QuickGO cross-references section) no
Is this term in a subset? (check the AmiGO page for that term) no
Any other information These two terms are both defined by EC:3.2.1.52, which is for (and is already an xref on) the more general term "beta-N-acetylhexosaminidase activity (GO:0004563)". The EC:3.2.1.52 entry says "Hydrolysis of terminal non-reducing N-acetyl-D-hexosamine residues in N-acetyl-beta-D-hexosaminides. Acts on N-acetylglucosides and N-acetylgalactosides. "
