Abstract

Exponentially growing cells of the gram-negative bacterium Chromobacterium violaceum demonstrate invaginations of the cytoplasmic membrane with a high frequency. These invaginations conform to the ultrastructural appearance of mesosomes of gram-positive bacteria. As many as four mesosomes are observed per cell, each of which may increase the total membrane surface of the cell by 30%. Washing of cells in dilute tris(hydroxymethyl)aminomethane buffer effects a distension of the mesosome "neck" and/or cytoplasmic membrane clarifying the association of the mesosome to the cytoplasmic membrane. Plasmolysis effects an eversion of the mesosome into the plasmolysis vacuole.

The removal of the type-2 copper from Rhus vernicifera laccase.

We have studied the removal of the type-2 copper from tree laccase (Rhus vernicifera) by treatment with EDTA at pH 5.2 in the presence of a redox buffer containing ferri- and ferrocyanide. The efficiency with which the copper is removed depends on the Fe(CN) 6(4-)/Fe(CN) 6(3-) ratio. We have varied this ratio from approx. 2:1 to about 50:1 and the best results were obtained with the highest ratio, i.e., the most cathodic solution potential. Nevertheless, the presence of Fe(CN) 6(3-) is required for the procedure to be effective. Although we cannot exclude the possibility that a mixed-valence form of laccase is the reactive species, we believe the results are better explained by a model which assumes that the removal of the type-2 copper depends upon an ordered sequence of oxidation-reduction reactions. Specifically, we propose that the copper is released as the monovalent ion from previously reduced laccase and then reoxidized in solution and sequestered with EDTA. The reoxidation step drives the reaction because recombination with the protein is inhibited when copper is in the divalent form. In testing this model, we have also shown that the type-2 copper can be removed under strictly reducing conditions when 4,4'-dicarboxy-2,2'-biquinoline (BCA) is present to complex the copper(I) ion. Although the BCA method is effective, the reaction takes longer, perhaps because of the limited solubility of BCA at the pH values of interest. Finally, we have found that the best results are obtained with either method when a cyanometalate ion such as Fe(CN) 6(3-) or Co(CN) 6(3-) is present in the medium. The exact role of this factor has yet to be established, but there is no indication that free cyanide has a role in the process. The most likely interpretation is that some type of binding interaction with the protein facilitates copper release.

Determination of cetirizine in serum using reversed-phase high-performance liquid chromatography with ultraviolet spectrophotometric detection.

A method using reversed-phase high-performance liquid chromatography with ultraviolet detection for the determination of ceterizine in serum is described. The method is sensitive down to 50 ng/ml (250-microliter loop). Sample preparation involves only serum deproteination with perchloric acid and injection of the centrifuged supernatant. Elution is at pH 2.5 with acetonitrile-methanol-0.05 M phosphate buffer (33:9:58, v/v) on a 25 cm x 4.6 mm I.D. Spherisorb S5 ODS2 column. Detection is at 211 nm, its lambda max. For levels above 300 ng/ml the serum sample size is 100 microliter and a 200-microliter sample is necessary for concentrations less than 300 ng/ml. At the 2 micrograms/ml concentration the intra-assay relative standard deviation is better than 2.2%, whilst the inter-assay deviation is 2.6% over eight samples. At 200 ng/ml the intra-assay relative standard deviation is 6% over seven samples. Detector response is linear from 100 ng/ml to 10 micrograms/ml (100-microliter loop).

Regeneration of functional hemoglobin from iron(III) hemoglobin by reduction with hydrogen and a heterogeneous catalyst.

Functional hemoglobin was regenerated from partially autoxidized hemoglobin by reduction with molecular hydrogen in the presence of a heterogeneous catalyst consisting of elemental platinum embedded in an electroactive polymer. The visible spectrum of the regenerated hemoglobin was identical to that of native iron(II) hemoglobin. The regenerated hemoglobin displayed highly cooperative oxygen-binding characteristics. P50 values for oxidized-regenerated hemoglobin samples were not different from native hemoglobin. The Hill coefficients for regenerated hemoglobin were slightly lower than the controls, possibly because of small amounts of irreversibly oxidized hemoglobin arising during the initial autoxidation. The advantages of the reduction system include: (1) the heterogeneous catalyst avoids the problem of protein adsorption onto bare platinum, (2) catalyst and reducing agent are easily removed from the protein, and (3) the by-product H+ is buffered easily.
