The biological notes and selected original evidence describe the source scope. The latter includes the exact interaction and urinary-vesicle table entries, accessible original downloads, and target-specific PAINT ancestry.
The review preserves 27 original annotations and adds one structurally supported oligosaccharide-binding assertion. One branching-enzyme core is retained. The canonical sequence has 702 residues; no alternative-product declaration was found. Structural fragments are not treated as natural products. Cation binding remains UNDECIDED.
Compact provenance links the committed GOA export, the committed observation archive with lossless raw contexts, literal urine extension, canonical sequence and older review/history records. The archive preserves 27 raw records, 29 historical quote locators and all 26 source fingerprints independently of branch retention; they are not fresh endorsements. Three current exact anchors total 15 words from PMID:26199317 and 10 from PMID:8613547. Repeated supports use references without repeating quotations.
The primary sources were read selectively, as specified per reference. Abstract-only assessments do not imply inspection of Methods, target tables or figures. No provider-generated research report is claimed: the cited manual research is in the notes and external-evidence page.
