== Publication Abstract from PubMed ==

Bacillus circulans T-3040 cycloisomaltooligosaccharide glucanotransferase (BcCITase) catalyses an intramolecular transglucosylation reaction and produces cycloisomaltooligosaccharides from dextran. BcCITase was overexpressed in Escherichia coli in two different forms and crystallized by the sitting-drop vapour-diffusion method. The crystal of BcCITase bearing an N-terminal His(6) tag diffracted to a resolution of 2.3 A and belonged to space group P3(1)21, containing a single molecule in the asymmetric unit. The crystal of BcCITase bearing a C-terminal His6 tag diffracted to a resolution of 1.9 A and belonged to space group P2(1)2(1)2(1), containing two molecules in the asymmetric unit.

[[http://www.uniprot.org/uniprot/CTA1_BACCI CTA1_BACCI]] Produces cycloisomaltooligosaccharide from dextran containing 7, 8 or 9 glucose units. The enzyme is specific for (1->6)-alpha-D-glucans (dextrans) and, without activity toward (1->4)-alpha-D-glucans, such as amylose. It also has no activity on oligosaccharides, such as amylopectin and pullulan, containing (1->6)-alpha-D-glucosidic linkages at branch points.<ref>PMID:7515357</ref>
