A MODULAR XYLANASE FROM MESOPHILIC CELLULOMONAS FIMI CONTAINS THE SAME CELLULOSE-BINDING AND THERMOSTABILIZING DOMAINS AS XYLANASES FROM THERMOPHILIC BACTERIA

摘要

The xynC gene from mesophilic Cellulomonas fimi encodes a large 125 kDa modular xylanase (XYLC), consisting of six distinct functional domains, In addition to a single Family 10 catalytic domain, XYLC contains a domain homologous with the nodulation protein, NodB, from nitrogen-fixing bacteria and thermostabilizing and cellulose-binding domains found previously only in xylanases from thermophilic bacteria.
