Cellulases hydrolyze cellulose, a major component of plant cell walls, to oligosaccharides and monosaccharides. Several Clostridium species secrete multi-enzyme complexes (cellulosomes) containing cellulases. C. thermocellum CelT, a family 9 cellulase, lacks the accessory module(s) necessary for activity, unlike most other family 9 cellulases. Therefore, characterization of the CelT structure is essential in order to understand its catalytic mechanism. Here, the crystal structure of free CelTDeltadoc, the catalytic domain of CelT, is reported at 2.1 A resolution. Its structure differs in several aspects from those of other family 9 cellulases. CelTDeltadoc contains an additional alpha-helix, alpha-helices of increased length and two additional surface-exposed beta-strands. It also contains three calcium ions instead of one as found in C. cellulolyticum Cel9M. CelTDeltadoc also has two flexible loops at the open end of its active-site cleft. Movement of these loops probably allows the substrate to access the active site. CelT is stable over a wide range of pH and temperature conditions, suggesting that CelT could be used to convert cellulose biomass into biofuel.
