Meristematic cells of pea cotyledonary buds blocked in G(0-1) state contain a small nucleolus with a large central clear area surrounded by a fibrillar rim. The nucleolar structure varies according to the cell cycle from the G(0-1)-blocked state until the first mitoses occurring between 24 and 27 h after removal of the main stem. In order to better identify and understand the role of the central area in the nucleolar function, its content was investigated by cytochemical and terminal deoxynucleotidyl transferase-immunogold methods. The central area showed the characteristics of a vacuole commonly constituted of the condensed chromatin, ribonucleoprotein granules, and lack of argyrophilic proteins. 3 h alter decapitation, a thickening of the fibrillar rim occurred, accompanied by an increase of granules in the vacuole. After 6 h, the unique vacuole broke up into two to four small vacuoles in which the granules are more abundant. After 12 h the nucleolus acquired compact structure with few minute vacuoles dispersed over the fibrillar component. During the whole cell cycle, the condensed chromatin is always observed in the vacuole. Our findings suggest that the appearance of the vacuoles is subsequent to the output of preribosomes from nucleolus. These vacuoles might play a role in condensation and decondensation of the chromatin. [less ▲]

LIKE various beta-lactamases, acylases and esterases1, the exocellular DD-carboxypeptidase-transpeptidase of Streptomyces R61 degrades benzylpenicillin and other beta-lactam antibiotics2-4. The R61 enzyme, however, markedly differs from the other penicillin-degrading enzymes in causing fragmentation of the penicillin nucleus. By using 8-14C-benzylpenicillin (benzyl labelled) as substrate, one of the fragments produced was shown to be 14C-phenylacetylglycine5. The reaction with the R61 enzyme is also peculiar in that it is a slow process. This is because of the long half life of the stoichiometnc complex transitorily formed between the antibiotic and the enzyme. Thus, for example, the value of the half life for the complex formed with benzylpenicillin is 80 min in 10 mM phosphate buffer (pH 7.0) and at 37 °C. As breakdown of the complex proceeds, however, phenylacetylglycine (when benzylpenicillin is used as substrate) is released and the enzyme concomitantly recovers its ability to bind penicillin. We have now characterised the fragment (hereby designated as the Y product) arising from the thiazolidine ring of penicillin as a result of the fragmentation of the antibiotic molecule by the R61 enzyme.

In order to measure Animal performance and, carcass and meat characteristics of Belgian Blue double-muscled culled females, a fattening trial was carried out on a total of 78 animals. Fifteen females were slaughtered at the beginning of the trial and 63 were fattened on a maize silage based diet. The initial average live weight was 571.2kg. The total fattening gain was 91.1 kg for a period of 91.4 days. At slaughter, the warm carcass weight was 405.9kg and the killing-out proportion 63.3%. The carcasses were characterised by a high proportion of muscles (67.6%) and rather low proportions of adipose tissue (18.2%) and bones (14.2%). The muscle and adipose tissue accretions were 36.0 and 28.2 kg. Meat was lean as indicated by high protein content (88.5%) and low fat content (6.6%) in dry matter. A high proportion of polyunsaturated fatty acids was also found (6.8 mol %). [less ▲]

A profile of free fatty acid (FFA) specificity in Acanthamoeba castellanii mitochondrial uncoupling is described. The FFA uncoupling specificity was observed as different abilities to stimulate resting respiration, to decrease resting membrane potential, and to decrease oxidative phosphorylation efficiency. Tested unsaturated FFA (C18-20) were more effective as uncouplers and protonophores when compared to tested saturated FFA (C8-18), with palmitic acid (C16:0) as the most active. As FFA efficiency in mitochondrial uncoupling is related to physiological changes of fatty acid composition (and thereby FFA availability) during growth of amoeba cells, it could be a way to regulate the activity of an uncoupling protein and thereby the efficiency of oxidative phosphorylation during a cell life of this unicellular organism.
