CC -!- FUNCTION: Virulence factor (PubMed:17041037). Involved in the
CC degradation of glycogen of the mammalian host cells. Hydrolyzes the
CC alpha-1,6-branchpoints of glycogen. Hydrolyzes pullulan. Does not
CC hydrolyze dextran. Binds to mouse lung alveolar type II cells that are
CC rich in glycogen stores. Is an alpha-glucan-specific carbohydrate-
CC binding protein, which binds to amylose (pure alpha-(1,4)-linked
CC glucose), amylopectin (alpha-(1,4)-linked glucose with alpha-(1,6)
CC branch points), pullulan (linear polymer of mixed alpha-(1,4)- and
CC alpha-(1,6)-linked glucose) and glycogen (similar to amylopectin with
CC more frequent alpha-(1,6) branch points) in vitro. Does not bind to
CC dextran (a linear polymer of alpha-(1,6)-linked glucose) (By
CC similarity). {ECO:0000250|UniProtKB:A0A0H2UNG0,
CC ECO:0000269|PubMed:17041037}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Hydrolysis of (1->6)-alpha-D-glucosidic linkages in pullulan,
CC amylopectin and glycogen, and in the alpha- and beta-limit dextrins
CC of amylopectin and glycogen.; EC=3.2.1.41;
CC Evidence={ECO:0000250|UniProtKB:A0A0H2UNG0};
CC -!- ACTIVITY REGULATION: Inhibited by 4-O-alpha-D-glucopyranosylmoranoline
CC (G1M). {ECO:0000250|UniProtKB:A0A0H2UNG0}.
CC -!- SUBCELLULAR LOCATION: Secreted, cell wall {ECO:0000255|PROSITE-
CC ProRule:PRU00477}; Peptidoglycan-anchor {ECO:0000255|PROSITE-
CC ProRule:PRU00477}. Cell surface {ECO:0000250|UniProtKB:Q9F930}.
CC Note=Localizes to cytoplasm in the lung alveolar type II cells of the
CC mouse and human hosts. {ECO:0000250|UniProtKB:A0A0H2UNG0}.
CC -!- DOMAIN: The N-terminal tandem family 41 carbohydrate-binding modules
CC (CBM) are involved in carbohydrate binding. The C-terminal glycosyl
CC hydrolase 13 (GH13) domain is involved in catalysis.
CC {ECO:0000250|UniProtKB:A0A0H2UNG0}.
CC -!- DISRUPTION PHENOTYPE: Reduced numbers of pneumococci relative to wild-
CC type 48 hours post-infection in the lungs and blood of the mouse
CC infection model confirming a role for this protein in invasive disease.
CC {ECO:0000269|PubMed:17041037}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 13 family. {ECO:0000305}.
