P46281 (CAHX_FLAPR) Reviewed, UniProtKB/Swiss-Prot

Names and origin

Protein names	Recommended name: Carbonic anhydrase EC=4.2.1.1 Alternative name(s): Carbonate dehydratase
Organism	Flaveria pringlei
Taxonomic identifier	4226 [NCBI]
Taxonomic lineage	Eukaryota › Viridiplantae › Streptophyta › Embryophyta › Tracheophyta › Spermatophyta › Magnoliophyta › eudicotyledons › core eudicotyledons › asterids › campanulids › Asterales › Asteraceae › Asteroideae › Heliantheae alliance › Tageteae › Flaveria

Protein attributes

Sequence length	329 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Reversible hydration of carbon dioxide.
Catalytic activity	H2CO3 = CO2 + H2O.
Subunit structure	Homohexamer By similarity.
Subcellular location	Cytoplasm Potential.
Domain	Possesses a transit-like peptide, but it is proposed that this peptide is not removed and that therefore the enzyme stays in the cytoplasm instead of going to the chloroplast By similarity.
Sequence similarities	Belongs to the beta-class carbonic anhydrase family.
