GENERAL INFORMATION
ORGANISM
UNIPROT ACCESSION NO.
COMMENTARY
LITERATURE
physiological function
-
when endo-beta-mannanase activity is much reduced by RNAi and antisense RNA strategies, their firmness is higher compared to those of control fruits at the turning and orange-color stages, but at the red-ripe stage firmness is similar between the two fruit-types
physiological function
Cellulosimicrobium sp.
G3FBL1
enzyme strongly binds to ivory nut mannan, Avicel, chitosan, and chitin, but does not attach to curdlan, insoluble oat spelt xylan, lignin, or poly(3-hydroxybutyrate)
physiological function
Q9FJZ3, Q9LZV3, Q9M0H6
germination time in T-DNA insertion mutant almost doubles compared to wild-type. Enzyme is important for the germination of Arabidopsis thaliana seeds by facilitating the hydrolysis of the mannan-rich endosperm cell walls; T-DNA insertion mutant germinates later than the wild type.

main enzyme activity in the fruit
Manually annotated by BRENDA team
-
transient expression in onion epidermal cells of endo-beta-mannanase trancripts fused to green fluorescent protein results in the expressed enzyme being localized to the cell walls. This occurs initially during ripening in the skin and outer pericarp of the fruit, and later in the skin and throughout the pericarp

The loss of amino acids from the C-terminal end of the protein indirectly affects the conformation of the catalytic Glu318 residue and stability of active site because of interactions between residues at the C-terminus and the rest of protein

production of enzyme by expression in Aspergillus niger under control of the Aspergillus niger glyceraldehyde-3-phosphate dehydrogenase promoter gpdP and the Aspergillus awamori glucoamylase terminator glaAT. The glucose concentration and the organic nitrogen source have an effect on both the volumetric enzyme activity and the specific enzyme activity. The highest mannanase activity levels of 16596 nkat ml-1 and 574 nkat mg-1 dcw are obtained for Aspergillus niger when cultivated in a process-viable medium containing corn steep liquor as the organic nitrogen source and high glucose concentrations
