Variation in the metalloenzyme activity of reef-building corals from Palau
Corals are a diverse class of animals that associate with an endosymbiont (dinoflagellates from the family Symbiodiniaceae). They vary significantly depending on species, which is reflected in physiological functions, such as enzyme activity. This study investigates whether the activities of two metalloenzymes, Carbonic Anhydrase (CA) and SuperOxide Dismutase (SOD), are modulated by symbiont identity, host identity, reef zone, and if their activity was correlated with the metal contents of the Symbiodiniaceae. Fragments of reef-building corals from six species were collected from two different reef environments in Palau with markedly different thermal histories. The symbiont genetic identity, metal contents, CA and SOD activity were measured for all samples. Metalloenzyme activity did not vary between corals from different reef locations. Instead, we found many differences in metalloenzyme activity of corals from different species. For some coral species, metal contents were correlated with metalloenzyme activity. However, more research needs to be conducted in order to fully understand the extent to which metalloenzyme activities are modulated by host-symbiont species pairings and their trace metal needs.
