Sponge microneedle powder Due to the particularity of its growth environment, Freshwater sponges gradually evolved the special bone, thats spongilla spicules. which is a siliceous spicules, very small, but has a stronger hardness, for supporting the sponge body and resisting the enemy's invasion. Spongilla spicules constituted by hard protein and heteronuclear hard protein, do not dissolve in any kind of organic solution, therefore, can be used as a kind of ideal natural materials in cosmetics and skin peeling. Freshwater sponges,usually attached to grow on the branches and corrupt leaves, the floating beings in the water and some parasitic algae, they will be salvaged with freshwater sponges together. But only the spongilla spicules are really will be used by. Other impurities are not beneficial to the skin, even cause skin allergies and infection.

spore photoproduct lyase This enzyme is a member of the 'AdoMet radical' (radical SAM) family. The enzyme binds a [4Fe-4S] cluster. The cluster is coordinated by 3 cysteines and an exchangeable SAM molecule. The 5'-deoxy-adenosine radical formed after electron transfer from the [4Fe-4S] cluster to the S-adenosyl-L-methionine, initiates the repair by abstracting the C-6 hydrogen of the spore photoproduct lesion. During the second part of the repair process the SAM molecule is regenerated. Group: Enzymes. Synonyms: SAM; SP lyase; SPL; SplB; SplG. Enzyme Commission Number: EC 4.1.99.14. CAS No. 37290-70-3.
