Function

MANA_CELJU Hydrolyzes mannan and galactomannan, but displays little activity towards other polysaccharides located in the plant cell wall. Appears to act in synergy with alpha-galactosidase (AgaA) to elicit hydrolysis of galactomannan. Preferentially hydrolyzes the larger oligosaccharides and has greater activity against non-substituted polysaccharides.[1] [2]

Publication Abstract from PubMed

Mutant endo-mannanases, in which the catalytic nucleophile has been replaced, function as glycosynthases in the synthesis of manno-oligosaccharides of defined lengths.
