Publication Abstract from PubMed
The truncated carbohydrate-active enzyme belonging to family 43 glycoside hydrolase from Clostridium thermocellum (CtGH43) is an alpha-L-arabinofuranosidase that in combination with endoxylanase leads to complete breakdown of L-arabinosyl-substituted xylans. The recombinant enzyme CtGH43 from C. thermocellum was overexpressed in Escherichia coli and purified by immobilized metal-ion affinity chromatography. The recombinant CtGH43 has a molecular mass of 35.86 kDa. Preliminary structural characterization was carried out on CtGH43 crystallized from different conditions, which gave either cube-shaped or brick-shaped crystals. These diffracted to a resolution of 1.65 A for the cubic form and 1.1 A for the monoclinic form. Molecular replacement was used to solve the CtGH43 structure.
