Taxonomic identifier

2336 [NCBI]

Taxonomic lineage

Bacteria › Thermotogae › Thermotogales › Thermotogaceae › Thermotoga

Protein attributes

Sequence length	1059 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Catalytic activity	Endohydrolysis of (1->4)-beta-D-xylosidic linkages in xylans.
Domain	The C-terminal CBM-cenC domains mediate the binding of xynA to microcrystalline cellulose. CBM-cenC 2 alone can also promote cellulose binding.
Sequence similarities	Belongs to the glycosyl hydrolase 10 (cellulase F) family. Contains 2 CBM-cenC (cenC-type cellulose-binding) domains.
Biophysicochemical properties	pH dependence: Optimum pH is 6.2. Temperature dependence: Optimum temperature is 90 degrees Celsius. Thermostable.
