23S rRNA (adenine2503-C8)-methyltransferase
This enzyme is a member of the 'AdoMet radical' (radical SAM) family. S-Adenosyl-L-methionine acts as both a radical generator and as the source of the appended methyl group. It contains an [4Fe-S] cluster. Cfr is an plasmid-acquired methyltransferase that protects cells from the action of antibiotics. The enzyme methylates adenosine at position 2503 of 23S rRNA by a radical mechanism, transferring a CH2 group from S-adenosyl-L-methionine while retaining the hydrogen at the C-8 position of the adenine. Cfr first transfers an CH2 group to a conserved cysteine (Cys338 in Staphylococcus aureus), the generated radical from a second S-adenosyl-L-methionine then attacks the methyl group, exctracting a hydrogen. The formed radical forms a covalent intermediate with the adenine group of the tRNA. The enzyme will also methylate 2-methyladenine produced by the action of EC 2.1.1.192 [23S rRNA (adenine2503-C2)-methyltransferase]. Group: Enzymes. Synonyms: Cfr (gene name). Enzyme Commission Number: EC 2.1.1.224. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.

25-Hydroxy Vitamin D3 3, 3- (4-Maleimidopropanamide) propyl Ether is an analog of Vitamin D3 (V676045), a vitamin that mediates intestinal calcium absorbtion, bone calcium metabolism and probably, muscle activity. Occurs in and is isolated from fish liver oils. Vitamin D acts through a receptor that is a member of the ligand-dependent transcription factor superfamily. Modulates the proliferation and differentiation of both normal and cancer cells. Has antiproliferative and antimetastatic effects on breast, colon, and prostate cancer cells. Activated vitamin D receptors in intestine and bone maintain calcium absorbance and homeostasis. Group: Biochemicals. Grades: Highly Purified. Pack Sizes: 2.5mg, 25mg. Molecular Formula: C37H56N2O5, Molecular Weight: 608.85. US Biological Life Sciences.
Vitamin D3 analog. Calcifediol (INN), also known as calcidiol, 25-hydroxycholecalcifero l, or 25-hydroxyvitamin D (abbreviated 25(OH)D),[1] is a prehormone that is produced in the liver by hydroxylation of vitamin D3(cholecalciferol) by the enzyme cholecalciferol 25-hydroxylase which was isolated by Michael F. Holick. Physicians worldwide measure this metabolite to determine a patient's vitamin D status.[2] At a typical daily intake of vitamin D3, its full conversion to calcifediol takes approximately 7 days.[3] Calcifediol is then converted in the kidneys (by the enzyme 25(OH)D-1α-hydroxylase) into calcitriol (1,25-(OH)2D3), a secosteroid hormone that is the active form of vitamin D. It can also be converted into 24-hydroxycalcidiol in the kidneys via 24-hydroxylation.[4][5]. Group: Biochemicals.
