The activity of the coral Stylophora pystillata secretory carbonic anhydrase STPCA has been tested in presence of amino acids and amines. All the investigated compounds showed a positive, activating effect on kcat and have been separated in weak (KA in the range of 21–126 μM), medium (10.1–19 μM) and strong enzyme activators (KA of 0.18–3.21 μM). D-DOPA was found to be the best coral enzyme activator, with an activation constant KA of 0.18 μM. This enhancement of STPCA activity, as well as previous enzyme inhibition results, might now be tested on living organisms to better understand the role played by these enzymes in the coral calcification processes.
