Names and origin

Protein namesRecommended name:
Cellulose synthase 2

Including the following 2 domains:

  1. Cellulose synthase catalytic subunit [UDP-forming]
    EC=2.4.1.12
  2. Cyclic di-GMP-binding domain
    Alternative name(s):
    Cellulose synthase 2 regulatory domain
Gene names
Name:acsAII
OrganismGluconacetobacter hansenii (Acetobacter hansenii)
Taxonomic identifier436 [NCBI]
Taxonomic lineageBacteriaProteobacteriaAlphaproteobacteriaRhodospirillalesAcetobacteraceaeGluconacetobacter

Protein attributes

Sequence length1596 AA.
Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Catalytic activity

UDP-glucose + (1,4-beta-D-glucosyl)(n) = UDP + (1,4-beta-D-glucosyl)(n+1).

Subcellular location

Cell inner membrane; Multi-pass membrane protein Potential.

Domain

There are two conserved domains in the globular part of the catalytic subunit: the N-terminal domain (domain A) contains the conserved DXD motif and is possibly involved in catalysis and substrate binding. The C-terminal domain (domain B) contains the QXXRW motif and is present only in processive glycosyl transferases. It could be involved in the processivity function of the enzyme, possibly required for holding the growing glycan chain in the active site.

Miscellaneous

It is not essential for cellulose production in this strain.

Sequence similarities

In the N-terminal section; belongs to the glycosyltransferase 2 family.

In the C-terminal section; belongs to the AcsB/BcsB family.

Contains 1 PilZ domain.
