Assigns GO:0030167 proteoglycan catabolic process through four alternative condition sets of CATH FunFams: beta-galactosidase (Euarchontoglires), alpha-L-iduronidase (no taxon condition), beta-hexosaminidase (Mus) and N-acetylglucosamine-6-sulfatase (Eukaryota).
Condition-set counts describe the sets recorded in this review, which may omit the full rule.
No domain overlap table is shown: the cached overlap analysis for this version of the review is not available.
Run just analyze-rule ARBA00085883 and re-render to add it.
All four live condition sets were examined. The Swiss-Prot matches of every set carry a descendant of GO:0030167 with experimental evidence: beta-galactosidase GLB1 (keratan sulfate proteoglycan catabolic process, IMP), alpha-L-iduronidase (dermatan sulfate and heparan sulfate proteoglycan catabolic process, IDA and IMP), mouse HEXA and HEXB (dermatan sulfate proteoglycan catabolic process, IGI) and N-acetylglucosamine-6-sulfatase (heparan sulfate proteoglycan catabolic process, IDA and IMP). Beta-galactosidase and beta-hexosaminidase also degrade gangliosides; that is a further function, not a reason to withhold this one.
Each set selects one lysosomal enzyme family whose reviewed members are experimentally annotated to a child of the rule's term. The taxon conditions on sets 1 and 3 are narrow, which limits coverage but does not make the annotation wrong.
Per-set receipts are in rule.condition_sets[].notes. Accessions listed are Swiss-Prot matches with experimental evidence for a descendant of GO:0030167 in QuickGO.

GO:0042340, GO:0030209 and GO:0030200 are descendants of GO:0030167.
GO:0030167 is the common parent of the three child terms the matched proteins are experimentally annotated to (GO:0042340 keratan sulfate, GO:0030209 dermatan sulfate and GO:0030200 heparan sulfate proteoglycan catabolic process). A per-set child term would be more specific.

review_summary: 'All four live condition sets were examined. The Swiss-Prot matches of every set carry
a descendant of GO:0030167 with experimental evidence: beta-galactosidase GLB1 (keratan sulfate proteoglycan
catabolic process, IMP), alpha-L-iduronidase (dermatan sulfate and heparan sulfate proteoglycan catabolic
process, IDA and IMP), mouse HEXA and HEXB (dermatan sulfate proteoglycan catabolic process, IGI) and
N-acetylglucosamine-6-sulfatase (heparan sulfate proteoglycan catabolic process, IDA and IMP). Beta-galactosidase
and beta-hexosaminidase also degrade gangliosides; that is a further function, not a reason to withhold
this one.'
action: ACCEPT
action_rationale: Each set selects one lysosomal enzyme family whose reviewed members are experimentally
annotated to a child of the rule's term. The taxon conditions on sets 1 and 3 are narrow, which limits
coverage but does not make the annotation wrong.

go_specificity:
assessment: APPROPRIATE
notes: GO:0030167 is the common parent of the three child terms the matched proteins are experimentally
annotated to (GO:0042340 keratan sulfate, GO:0030209 dermatan sulfate and GO:0030200 heparan sulfate
proteoglycan catabolic process). A per-set child term would be more specific.

confidence: 0.8
corrections:
- date: '2026-11-10'
withdrawn_claim: Condition sets 1 (beta-galactosidase) and 3 (beta-hexosaminidase) should be removed
because the primary role of these enzymes is ganglioside catabolism.
correction: Both families are experimentally annotated to proteoglycan catabolism. A protein can take
part in two processes; the second does not make the first wrong.

- date: '2026-11-10'
withdrawn_claim: GO:0030167 is too broad for sets 1 and 3 because it does not capture ganglioside metabolism.
correction: Ganglioside catabolism is in a different branch of GO and is not a more specific form of
proteoglycan catabolism, so this is not a specificity problem.

correction: GO:1902556 is phosphatidylinositol transporter complex; GO:0006689 is ganglioside catabolic
process; GO:0006687 is glycosphingolipid metabolic process. The dermatan sulfate term is GO:0030209.

withdrawn_claim: Condition set 3 is restricted to taxon 862507 (Mus), "mouse and rat genera"; sets 1

correction: The live rule restricts set 3 to genus Mus (NCBITaxon:10088), set 1 to Euarchontoglires
and set 4 to Eukaryota. Rats are genus Rattus.
