Title:
NOVEL CERAMIDASE AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/029630
Kind Code:
A1
Abstract:
[PROBLEMS] To obtain a novel enzyme which is derived from a microorganism, particularly
a mold showing a high growth capability on a plastic surface having an urethane
bond and can break an urethane bond and/or an amide bond in a polymeric substance,
and to provide a method for degradation of a plastic material having an urethane
bond by using the enzyme. [MEANS FOR SOLVING PROBLEMS] Disclosed is a ceramidase
comprising either of the proteins (a) and (b): (a) a protein comprising the amino
acid sequence depicted in SEQ ID NO:1; and (b) a protein comprising an amino acid
sequence having the deletion, substitution or addition of one or several amino
acid residues in the amino acid sequence depicted in SEQ ID NO:1 and having a ceramidase
activity.
