Sysname
beta-D-arabinofuranoside non-reducing end beta-D-arabinofuranosidase (configuration-retaining)
Reaction(IUBMB)
Hydrolysis of terminal non-reducing beta-D-arabinofuranoside residues in D-arabinans
Comment
The enzyme, characterized from the bacterium Microbacterium arabinogalactanolyticum, hydrolyses beta-D-arabinofuranosides from the non-reducing terminal of D-arabinan core structure of lipoarabinomannan and arabinogalactan of mycobacterial cell wall. cf. EC 3.2.1.55, non-reducing end alpha-L-arabinofuranosidase; EC 3.2.1.185, non-reducing end beta-L-arabinofuranosidase; EC 3.2.1.225, D-arabinan exo alpha-(1,3)/(1,5)-arabinofuranosidase (non-reducing end); and EC 3.2.1.226, D-arabinan endo alpha-(1,5)-arabinofuranosidase.
