Enzymatic Activity in the M Band
Experiments which combined histochemistry and electron microscopy were performed in studying the sites of enzymatic hydrolysis of thiolacetic acid in the presence of lead ions in diaphragmatic and cardiac muscle. I t was found that in these striated muscles the electron opaque, final product of the histochemical reaction (PbS) was discretely deposited on the swelling of the thick elemental fila...

متن کاملThe M Band
The M band can be extracted from fibrils suspended in 5 mM Tris buffer, pH 8.0, for 15 min. The M band is completely removed only from fibrils of sarcomere lengths greater than 2.1 micro. Extraction does not alter the fluorescent antimyosin staining pattern of the A band, thus providing strong evidence that no alteration of the structural integrity of the thick filament has occurred. Fluorescen...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولThe enzymatic conjugation of m-aminophenol.
It has been demonstrated by many workers (l-5) that phenols may be conjugated with glucuronic acid or inorganic sulfate in vitro by liver slices and by cell-free preparations. By using a system developed in this laboratory, together with a modification of the analytical procedure described by Levvy and Storey (3), the synthesis of the conjugated sulfate, and possibly of the glucuronide, has bee...
