Organism

Rhodothermus marinus (strain ATCC 43812 / DSM 4252 / R-10) (Rhodothermus obamensis) [Complete proteome] [HAMAP]

Taxonomic identifier

518766 [NCBI]

Taxonomic lineage

Bacteria › Bacteroidetes › Bacteroidetes Order II. Incertae sedis › Rhodothermaceae › Rhodothermus

Protein attributes

Sequence length	558 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Acts as endo-acting enzyme with a requirement for at least five sugar moieties for effective catalytic activity. Hydrolyzes carob-galactomannan (locust bean gum) effectively and to a smaller extent guar gum, but not yeast mannan. Ref.1
Catalytic activity	Random hydrolysis of (1->4)-beta-D-mannosidic linkages in mannans, galactomannans and glucomannans.
Sequence similarities	Belongs to the glycosyl hydrolase 26 family. Contains 1 CBM6 (carbohydrate binding type-6) domain.
Biophysicochemical properties	pH dependence: Optimum pH is 5.4. Ref.1 Temperature dependence: Optimum temperature is 85 degrees Celsius.
Sequence caution	The sequence CAA62442.1 differs from that shown. Reason: Erroneous initiation.
