'''EXPANSION OF THE GLYCOSYNTHASE REPERTOIRE TO PRODUCE DEFINED MANNO-OLIGOSACCHARIDES'''<br />


==Overview==
==Expansion of the glycosynthase repertoire to produce defined manno-oligosaccharides==
Mutant endo-mannanases, in which the catalytic nucleophile has been, replaced, function as glycosynthases in the synthesis of, manno-oligosaccharides of defined lengths.

== Function ==
[https://www.uniprot.org/uniprot/MANA_CELJU 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.<ref>PMID:7848261</ref> <ref>PMID:11064195</ref>
