Abstract

The controlled synthesis of oligosaccharides is of growing interest due to the important roles of oligosaccharides in various biological processes. Enzymatic synthesis enables regio- and stereo-selective control during synthesis which still remains a challenge using total chemical synthesis. In this study, endoplasmic reticulum 1,2-α-mannosidase from Glaciozyma antractica was recombinantly expressed in Pichia pastoris. The gene sequence for ER mannosidase was obtained from the Glaciozyma antractica database. The BLAST (Basic Local Alignment Search Tool) results from bioinformatics screening showed that ER mannosidase had 41 % identity with the equivalent mannosidases from Sacchromyces cerevesiae. ER mannosidase from G. antartica was then cloned into the pPICZαC expression vector and used to transform in the host Pichia pastoris X33 cells. The ER mannosidase (MW∼58 kDa) was successfully expressed at 25 °C with 1.0 % methanol induction.
