Abstract
The coupling reaction between cyclomalto-hexaose and isomaltose, catalysed by Bacillus macerans transglycosylase, was carried out and the products were degraded with [beta]-amylase. A tri-saccharide, proved to be 6-[alpha]-maltosylglucose, was isolated as a [beta]-amylase-resistant end product. A tetrasaccharide, believed to be 6-[alpha]-maltotriosylglucose, was also isolated. This was slowly hydrolysed by [beta]-amylase. The rate of hydrolysis of 6-[alpha]-maltosylglu-cose in hot aqueous acid is the same as of the isomeric trisaccharide panose (4-[alpha]-isomaltosylglucose).
