Novel GH10 Xylanase, with a Fibronectin Type 3 Domain, from <i>Cellulosimicrobium</i> sp. Strain HY-13, a Bacterium in the Gut of <i>Eisenia fetida</i>

Abstract

The gene encoding a novel modular xylanase from Cellulosimicrobium sp. strain HY-13 was identified and expressed in Escherichia coli, and its truncated gene product was characterized. The enzyme consisted of three distinct functional domains, an N-terminal catalytic GH10 domain, a fibronectin type 3 domain, and C-terminal carbohydrate-binding module 2.
