Phosphatase activity in the sea
Did you know?
WebPhosphatase is a key-enzyme in the marine environment, although life in the sea is normally not P limited. Expression of phosphatase in algae is generally regulated by the prevailing external concentration of inorganic phosphate, but the internal N:P ratio may also play a role.
