kinetic properties of serratia marcescens adenosine 5'-diphosphate glucose pyrophosphorylase.the regulatory properties of partially purified adenosine 5'-diphosphate-(adp) glucose pyrophosphorylase from two serratia marcescens strains (atcc 274 and atcc 15365) have been studied. slight or negligible activation by fructose-p2, pyridoxal-phosphate, or reduced nicotinamide adenine dinucleotide phosphate (nadph) was observed. these compounds were previously shown to be potent activators of the adpglucose pyrophosphorylases from the enterics, salmonella typhimurium, enterobacter aerogenes, e ...19766432
somatic antigens of shigella. structural investigation on the o-specific polysaccharide chain of shigella dysenteriae type 1 lipopolysaccharide.the o-specific polysaccharide obtained from the lipopolysaccharide of shigella dysenteriae type 1 (shigella shiga) by mild acid hydrolysis followed by fractionation on sephadex g-50 was found to be identical to that desribed by morgan's group and was composed of l-rhamnose, d-galactose and n-acetyl-d-glycosamine in a ratio 2:1:1. on the basis of methylation analysis data the polysaccharide was proved to be a linear chain of monosaccharide residues in pyranose forms substituted at position 3, exc ...19768314
new sugars from antigenic lipopolysaccharides of bacteria: identification and synthesis of 3-o-(r)-1-carboxyethyl-l-rhamnose, an acidic component of shigella dysenteriae type 5 lipopolysaccharide.a new acidic sugar, 3-o-(r)-1-carboxyethyl-l-rhamnose (1), has been identified as a constituent of the o-antigenic lipopolysaccharide of sh. dysenteriae type 5. the structure of 1 has been established by physico-chemical methods and by synthesis. alkylation of methyl 2,5-di-o-benzyl-alpha-l-rhamnofuranoside (6) with (s)- or (r)-2-chloropropionic acids, followed by removal of the protecting groups, afforded 3-o-(r)-1-carboxyethyl-l-rhamnose (9) and 3-o-(s)-1-carboxyethyl-l-rhamnose (10), respecti ...197612866
liver enzyme adaptation after lithium administration in handled and nonhandled rats.we have examined the interaction of lithium administration and the infant stimulation procedure of handling on hormonally regulated enzymes of liver. animals handled in infancy show an increased morning corticosterone level in response to lithium feeding and markedly elevated serum glucose during refeeding following a two day fast, when compared to non-handled control animals. lithium alters serum corticosterone both in response to the stress of fasting, and during the diurnal cycle following gl ...197721840
calf liver nuclear n-acetyltransferases. purification and properties of two enzymes with both spermidine acetyltransferase and histone acetyltransferase activities.calf liver contains two nuclear n-acetyltransferases which are separated by chromatography on hydroxylapatite. both acetyltransferase a and acetyltransferase b will transfer acetate from acetyl-coa to either histone or spermidine. the same protein catalyzes the reaction with both substrates; this is shown by a constant ratio of spermidine to histone activity over a 5,000-fold purification and identical heat denaturation kinetics for both spermidine and histone acetyltransferase activity with eac ...197822543

ultrastructural localization of viral antigens using the unlabeled antibody-enzyme method.employing the unlabeled antibody enzyme method at the ultrastructural level, a comparison was made between preembedding staining and postembedding staining for the detection of viral antigens. the bacteriophage p1 absorbed to the surface of shigella dysenteriae was used as a model system. preembedding staining resulted in the specific deposition of peroxidase-antiperoxidase (pap) complexes as an electron-dense coating around the viral heads. disadvantages of the preembedding staining method incl ...197657192
particulate cytochrome c in agrobacterium agrobacterium tumefaciens the main part of c-type cytochromes is tightly bound to the bacterial cell envelope structures. several techniques were attempted to solubilize these cytochromes. the highest yield of cytochromes released is obtained by treatment of particle suspensions with 5% triton x-100. further purification confirms that the proteins are not really solubilized, but still aggregated in small heterogeneous complexes. chromatography on a cm-cellulose column demonstrates that at lea ...197558606

studies on the pathogenesis of enteric infections caused by invasive bacteria.salmonellae, shigellae and some escherichia coli must invade the intestinal epithelial cell and multiply within the mucosa to cause disease. although the bacterial cell most likely possesses several properties essential to this invasive ability, the nature of the cell envelope complex is at present the only characteristic which has been implicated in this process. while a number of pathophysiological events result from invasion, some of our recent efforts have concerned the site and mechanism of ...197662646
sh. dysenteriae serotypes2,4,8-immunochemistry and phage receptor activity.among three analyzed serotypes of shigella dysenteriae, namely, the serotypes 2,4 and 8, the serotype 2 proved to be a strong immunogen in rabbits, inducing anti-polysaccharide antibodies as well as antiprotein antibodies in all the animals. in contrast, the serotypes 4 and 8 were weak immunogens and among the rabbits some have synthesized only anti-proteins while others had antibodies against the somatic conjugate. aside from the somatic antigens, large amounts of proteins were isolated from al ...197663197

pleiotropic effect of a rifampin-resistant mutation in bacillus subtilis.rifampin-resistant (rifr) mutants were isolated spontaneously from bacillus subtilis strain 168. a fraction of the mutants did not grow on a minimal medium. a high concentration of one of the l-amino acids (glutamic acid, glutamine, arginine, proline, aspartic acid, or asparagine) was required to restore their growth on the medium. further analysis of one of the mutants (strain rf 161) suggested that the mutant is unable to use ammonia as a nitrogen source and requires amino acids instead. activ ...197898517
