CC -!- FUNCTION: Endo-1,5-alpha-L-arabinanase involved in degradation of
CC pectin. Its preferred substrate is linear 1,5-alpha-L-arabinan (By
CC similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Endohydrolysis of (1->5)-alpha-arabinofuranosidic linkages in
CC (1->5)-arabinans.; EC=3.2.1.99;
CC -!- PATHWAY: Glycan metabolism; L-arabinan degradation.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 43 family. {ECO:0000305}.
