Action of three GH51 and one GH54 α-arabinofuranosidases on internally and terminally located arabinofuranosyl branches.

The action of three glycoside hydrolase family GH51 and one GH54 α-arabinofuranosidases (ABFs) was studied on polymeric arabinoxylan and arabinoxylooligosaccharides. The substrates covered all possible arabinofuranosyl (Araf) substituents, i.e., terminal and internal α(1→2) and α(1→3)-linked Araf monosubstitutions and disubstitutions. The GH51 ABFs removed… CONTINUE READING
