signal peptidase I The enzyme is found in bacterial membranes and in chloroplast thylakoid membranes. Unaffected by inhibitors of most serine peptidases, but site-directed mutagenesis implicates a Ser/Lys catalytic dyad in activity. Hydrolyses a single bond -Ala?Ala- in M13 phage procoat protein, producing free signal peptide and coat protein. Formerly included in EC 3.4.99.36. Eukaryote signal peptidases that may have somewhat different specificity are known from the endoplasmic reticulum membrane and mitochondrial inner membrane. Type example of peptidase family S26. Group: Enzymes. Synonyms: leader peptidase I; signal proteinase. Enzyme Commission Number: EC 3.4.21.89. CAS No. 65979-36-4. Storage: Store it at +4 ?C for short term.

Silica Amorphous silica is a solid substance (silicon dioxide) that occurs in various form in nature (e.g. sand, quartz, minerals). It comes as spherical shaped fine powder. The particles are porous in nature and improves the smoothness of powders while providing an excellent aesthetic feel. Particle size 2.0 - 15.0 microns. Purity 100%. Note: Silica is amorphous, not crystalline. Because of this, a Prop 65 warning is not required. Uses: Sun care products, skin care products, color cosmetics e.g. makeup & powders, hair care products.
