title: Carbonic anhydrase from Camelia sinensis (tea) leaves.
abstract: Carbonic anhydrase (CA) (carbonate hydrolyase; E,C,4.2.1.1) from leaves of mature Camelia sinensis was purified and characterized. The purification level was 53 fold. The optimum temperature for maximal enzyme activity is 50 degrees C. The optimum pH was 6.8 and this pH varied between 6.5 and 7.5. Each enzyme molecule is a hexamer with an M(r) of 169,000 with subunits of M(r) = 28,000.
