Specifically, CBM29-1-2 from Piromyces equi was separately linked to the N- and C-termini of GaO. Results Both GaO-CBM29 and CBM29-GaO were successfully expressed in Pichia pastoris, and demonstrated enhanced binding to galactomannan, galactoglucomannan and galactoxyloglucan. The position of the CBM29 fusion affected the enzyme function.

They liberate short-chain β-1,4-manno-oligomers, which can be further hydrolyzed to mannose by β-mannosidases (EC 3.2.1.25; Li et al., 2006 ). Glucomannan, galactomannan, galactoglucomannan (GGM) and linear mannans are the four subfamilies of the mannan family (Reference de Petkowicz, Reicher and Chanzy 22). The backbone of all mannan polysaccharides contains β(1–4)-linked mannose or a combination of mannose and glucose residues, which can be substituted with α(1–6)-linked galactose ( Reference Chauhan, Puri and Sharma 23 ) . The thickened endosperm cell walls of tobacco seeds are rich in a galactomannan (or possibly a low-Glc galactoglucomannan) with a very low degree of Gal substitution (Man/Gal about 20; over 70% of the tobacco galactomannan is solubilized from the endosperm cell walls by the action of a pure endo-[1→4]-β-d-mannanase, and the Man/Gal values quoted here and below are inferred from the Galactomannan was coupled to a protein carrier for the preparation of monoclonal antibodies.

Structural changes in galactomannan on germination of lucerne, carob, honey locust, guar and soybean seeds, as measured by viscosity, elution volumes on gel filtration and ultra-centrifugation were slight consistent with a rapid and complete hydrolysis of a molecule once hydrolysis of the mannan chain starts. β-Mannanase activity increased and then decreased, paralleling galactomannan depletion.
