Protein attributes

Sequence length	358 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Endo-1,5-alpha-L-arabinanase involved in degradation of pectin. Its preferred substrate is linear 1,5-alpha-L-arabinan By similarity.
Catalytic activity	Endohydrolysis of (1->5)-alpha-arabinofuranosidic linkages in (1->5)-arabinans.
Pathway	Glycan metabolism; L-arabinan degradation.
Subcellular location	Secreted By similarity.
Sequence similarities	Belongs to the glycosyl hydrolase 43 family.
Sequence caution	The sequence EED53222.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
