  • Feraxanase, a highly specific enzyme for hydrolysis of complex polysaccharides
    Patent number: 4954447
    Abstract: This invention relates to a composition comprising a substantially pure enzyme capable of degrading arabinoxylan and having a molecular weight of about 45,000. More preferably this invention relates to such an enzyme which has a pH optimum between about 6.5 to about 7.0. The enzyme is derived from bacteria capable of hydroloyzing plant cell wall material, preferably from Bacillus most preferably from Bacillus subtilis. This invention further relates to such a composition which is further capable of selectively dissociating feraxan from a maize cell wall preparation. Additionally, compositions of this invention are unable to degrade Rhodymenia (1.fwdarw.3),(1.fwdarw.4)-.beta.-D-xylan and larch arabino-(1.fwdarw.4)-.beta.-D-xylan.
