Accepted name: arabinan endo-1,5-α-L-arabinanase

Reaction: Endohydrolysis of (1→5)-α-arabinofuranosidic linkages in (1→5)-arabinans

Other name(s): endo-1,5-α-L-arabinanase; endo-α-1,5-arabanase; endo-arabanase; 1,5-α-L-arabinan 1,5-α-L-arabinanohydrolase; arabinan endo-1,5-α-L-arabinosidase (misleading)

Systematic name: 5-α-L-arabinan 5-α-L-arabinanohydrolase

Comments: Acts best on linear 1,5-α-L-arabinan. Also acts on branched arabinan, but more slowly.
