| 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.

| Metalloproteinase from Staphylococcus aureus | A metalloproteinase, or metalloprotease, is any protease enzyme whose catalytic mechanism involves a metal. An example of this would be meltrin which plays a significant role in the fusion of muscle cells during embryo development, in a process known as myogenesis.

The ligands co-ordinating the metal ion can vary with histidine, glutamate, aspartate, lysine, and arginine. The fourth coordination position is taken up by a labile water molecule. Treatment with chelating agents such as EDTA leads to complete inactivation. EDTA is a metal chelator that rem...tial for activity. They are also inhibited by the chelator orthophenanthroline.

| Methicillin Sodium, USP | Methicillin sodium is a narrow spectrum β-lactam antibiotic related to Penicillin. β-lactams interfere with PBP (penicillin binding protein) activity involved in the final phase of peptidoglycan synthesis. PBPs are enzymes which catalyze a pentaglycine crosslink between alanine and lysine residues providing additional strength to the cell wall. Without a pentaglycine crosslink, the integrity of the cell wall is severely compromised and ultimately leads to cell lysis and death. Resistance to β-lactams is commonly due to cells containing plasmid encoded β-lactamases. Methicillin is mostly resistant to β-lactamases. Methicillin targets primarily the cell wall of Gram positive organisms especially Staphylococcus aureus. Group: Biochemicals. Alternative Names: Sodium (2, 6-dimethoxyphenyl) penicillin; (2S, 5R, 6R) -6-[ (2, 6-Dimethoxybenzoyl) amino]-3, 3-dimethyl-7-oxo-4-thia-1-azabicyclo[3. 2. 0]heptane-2-carboxylic Acid Sodium Salt; Meticillin; Staphcillin.

| Native Staphylococcus aureus α-Hemolysin | α-Hemolysin is a 33 kDa extracellular protein secreted by most strains of pathogenic Staphylococcus aureus. It is selectively hemolytic and has a marked preference for rabbit red blood cells. It induces dermonecrosis, spastic muscle paralysis, and it is lethal for laboratory animals. The toxin must be in the monomeric form to initially bind to a membrane and specific receptors are not required for binding. Upon binding to biological membranes and/or artificial membranes, self-oligomerization occurs, resulting in ring structures (hexameric aggregates) believed to represent transmembrane pores, which are permeable to ions and small metabolites.

| Native Staphylococcus aureus Staphopain A | Staphopains A and B are part of the staphylococcal proteolytic cascade (SPC) and may contribute to tissue invasion and metastatic infections of Staphylococcus aureus. Staphopain A, along with Staphopain B, may contribute to septic shock through the release of bradykinin and S-kinin from human kininogens. This activity required proteolytically-active Staphopain A and was augmented by Staphopain B. Staphopain a is inhibited by staphostatin a, e-64, and heavy metal ions such as hg2+ and ag+. staphopain a is also inhibited by plasma α2-macroglobulin but not by human cystatin c. staphopain a and staphopain b, members of the peptidase c47 family, are the major cysteine proteases secreted by s. aureus.
