  • Title: Exo-arabinanase of Penicillium chrysogenum able to release arabinobiose from alpha-1,5-L-arabinan.
    Author: Sakamoto T, Thibault JF.
    Journal: Appl Environ Microbiol; 2001 Jul; 67(7):3319-21. PubMed ID: 11425761.
    Abstract:
    An exo-arabinanase, designated Abnx, was purified from a culture filtrate of Penicillium chrysogenum 31B by ammonium sulfate precipitation, anion-exchange chromatography, and hydrophobic chromatography. Abnx had an apparent molecular mass of 47 kDa. The enzyme released only arabinobiose from the nonreducing terminus of alpha-1,5-L-arabinan and showed no activity towards p-nitrophenyl-alpha-L-arabinofuranoside and alpha-1,5-L-arabinofuranobiose. Abnx is the first enzyme with this mode of action.
