Tethya aurantia

Proteins papain/cathepsin-L protease fonily (Mar spicules of Tethya aurantia, Porif. from California Shimizu 1998 Land kidney of Mamm. and tropical fruits of Ang. MI). 

A further major breakthrough in silicon biochemistry came from recent studies with the common marine sponge Tethya aurantia. After dissolution of the silica with buffered hydrofluoric acid, these filaments can be isolated, purified, and resolved into three very similar silicon-free subunits, named silicatein (silica protein) a, p, and y. Analyses of the... 

We have now found that in those rare cases ( 1 %) in which the silica spicules made by Tethya aurantia exhibit a bifurcation or cruciform structural anomaly, the axial filament within the silica had first bifurcated, supporting the suggestion that the silicification reaction was directed by (and followed the course of) the protein filament.

Isopropyl alcohol extracts of the sponge Tethya aurantia were fractionated for a component with negative chronotropic and inotropic activity on isolated guinea pig atria 181). The bioactive substance was found to be adenosine. The extracts also contained allantoin (293), which is an intermediate in the purinolytic sequence. Dichloromethane and methanol extracts of a new species of the genus Echinodictyum showed strong activities on the isolated guinea-pig trachea 182). The active constituent was identified as 4-amino-5-bromopyrrolo[2,3-d]pyr-imidine (294).

The following ethers were isolated from phospholipids of the species Tethya aurantia collected in Galifomia (Smith and Djerassi, 1987) and Stelletta sp. in Korea (Lee et al, 2003b).
