Resumen
ABSTRACT Analogues based on the insect cecropin–bee melittin hybrid peptide (CEME) were studied and analyzed for activity and salt resistance. The new variants were designed to have an increase in amphipathic α-helical content (CP29 and CP26) and in overall positive charge (CP26). The α-helicity of these peptides was demonstrated by circular dichroism spectroscopy in the presence of liposomes. CP29 was shown to have activity against gram-negative bacteria that was similar to or better than those of the parent peptides, and CP26 had similar activity. CP29 had cytoplasmic membrane permeabilizati

Resumen
ABSTRACT We previously demonstrated that ubiquitously expressed CP2c exerts potent erythroid-specific transactivation of α-globin through an unknown mechanism. This mechanism is reported here to involve specific CP2 splice variants and protein inhibitor of activated STAT1 (PIAS1). We identify a novel murine splice isoform of CP2, CP2b, which is identical to CP2a except that it has an additional 36 amino acids encoded by an extra exon. CP2b has an erythroid cell-specific transcriptional activation domain, which requires the extra exon and can form heteromeric complexes with other CP2 isoforms,

Resumen
CP26, CP29 and three different LHC II subcomplexes have been purified from a carnation photosystem II (PSII) preparation using non-denaturing isoelectric focusing in a vertical polyacrylamide slab gel. The identity of the fractions was established by absorption spectroscopy, SDS-PAGE and immunoblotting. CP26 comprised a single apoprotein of 26.6 kDa and CP29 contained two apoproteins of 28.8 and 28.5 kDa. LHC II subcomplex A consisted of Lhcb1 homotrimers, and subcomplexes B and C consisted of Lhcb1/Lhcb2 and Lhcb1/Lhcb3 heterotrimers, respectively. We discuss the data in relation to the organ

Resumen
ABSTRACT The genome of the type strain (B31) of Borrelia burgdorferi, the causative agent of Lyme disease, is composed of 12 linear and 9 circular plasmids and a linear chromosome. Plasmid content can vary among strains, but one 26-kb circular plasmid (cp26) is always present. The ubiquitous nature of cp26 suggests that it provides functions required for bacterial viability. We tested this hypothesis by attempting to selectively displace cp26 with an incompatible but replication-proficient vector, pBSV26. While pBSV26 transformants contained this incompatible vector, the vector coexisted with

Photosystem II (PS II) is a photosynthetic reaction center found in higher plants which has the unique ability to evolve oxygen from water. Several groups have formed two-dimensional PS II crystals or have isolated PS II complexes and studied them by electron microscopy and image analysis. The majority of these specimens have not been well characterized biochemically and have yielded relatively low resolution two-dimensional projection maps with a variety of unit cell sizes. We report the characterization of the polypeptide and lipid content of tubular crystals of PS II. The crystals contain t

Resumen
ABSTRACT We have inactivated the ospC, oppAIV, andguaB genes on the 26-kb circular plasmid of Borrelia burgdorferi (cp26) by allelic exchange. On several occasions following such transformations, the cp26 of transformants had an aberrant mobility through agarose gels. Characterization of these cp26 molecules showed that the plasmid had dimerized. These dimers were quite stable during either selective or nonselective passage. Subsequent transformations with dimer DNA supported the hypothesis that in B. burgdorferi, transforming cp26 DNA most likely does not displace the resident homologous plas

Photosystem II (PSII) in the thylakoid membranes of plants, algae, and cyanobacteria catalyzes light-induced oxidation of water by which light energy is converted to chemical energy and molecular oxygen is produced. In higher plants and most eukaryotic algae, the PSII core is surrounded by variable numbers of light-harvesting antenna complex II (LHCII), forming a PSII–LHCII supercomplex. In order to harvest energy efficiently at low–light-intensity conditions under water, a complete PSII–LHCII supercomplex (C2S2M2N2) of the green alga Chlamydomonas reinhardtii (Cr) contains more antenna subuni

ABSTRACTBorrelia burgdorferiis the tick-borne bacterium that causes the multistage inflammatory disease Lyme disease.B. burgdorferihas a reduced genome and lacks the enzymes required forde novosynthesis of purines for synthesis of RNA and DNA. Therefore, this obligate pathogen is dependent upon the tick vector and mammalian host environments for salvage of purine bases for nucleic acid biosynthesis. This pathway is vital forB. burgdorferisurvival throughout its infectious cycle, as key enzymes in the purine salvage pathway are essential for the ability of the spirochete to infect mice and crit

Abstract The relationship between the oral efficacy and the acute toxicity of hydroxypyridin-4-one iron chelators has been investigated to clarify structure-function relationships of these compounds in vivo and to identify compounds with the maximum therapeutic safety margin. By comparing 59Fe excretion following oral or intraperitoneal administration of increasing doses of each chelator to iron-overloaded mice, the most effective compounds have been identified. These have partition coefficients (Kpart) above 0.3 in the iron-free form with a trend of increasing oral efficacy with increasing Kp

Resumen
The new trifluoroethoxo phosphine complexes [Cp2M(?1-dppe)(CF3CH2O)]+ and [Cp2(CF3CH2O)M(?-dppe)MCp2(CF3CH2O)]2+ (M = Mo or W, Cp = ?-C5H5 and dppe = Ph2PCH2CH2PPh2) have been prepared by reaction of cationic di-?-hydroxo dinuclear complex of molybdenocene or tungstenocene [Cp2M(?-OH)2MCp2]2+ with dppe. From the 1H and 31P NMR data, the configurations of the products could be assigned. Furtheremore, X-ray crystallography was used to definitively identify one of the product [Cp2(CF3CH2O)Mo(?-dppe)MoCp2(CF3CH2O)]2+, which crystallizes in space group P21/c(#14) with a = 12.230(5) ?, b = 11.149(5)

Resumen
Heavy metal tolerant plants have phytoremediation potential for the recovery of contaminated soils, and the characterization of their metabolic adaptation processes is an important starting point to elucidate their tolerance mechanisms at molecular, biochemical and physiological levels. In this research, the effects of Cd and Pb on growth and protein carbonylation in tissues of Paspalum fasciculatum exposed to 30 and 50 mg·Kg-1 Cd and Pb respectively were determined. P. fasciculatum seedlings exposed to metals grew more than controls until 60 days of cultivation and limited their oxidative eff

Resumen
ABSTRACTThe strains ofXanthomonas axonopodispv. citri, the causative agent of citrus canker, are historically classified based on bacteriophage (phage) sensitivity. Nearly allX. axonopodispv. citri strains isolated from different regions in Japan are lysed by either phage Cp1 or Cp2; Cp1-sensitive (Cp1s) strains have been observed to be resistant to Cp2 (Cp2r) andvice versa. In this study, genomic and molecular characterization was performed for the typing agents Cp1 and Cp2. Morphologically, Cp1 belongs to theSiphoviridae. Genomic analysis revealed that its genome comprises 43,870-bp double-s

Resumen
SUMMARY Purpose To investigate the effect of a cervical cavity extending 1 mm apical to the cemento–enamel junction (CEJ) on fracture resistance and failure mode of maxillary central incisors that have been treated endodontically, present with complete and incomplete ferrules, and are restored with and without a fiber post. Methods and Materials 50 intact human maxillary central incisors were divided into five groups (n=10): CG (control group) 6-mm fer-rule height, no cervical cavity, and without post; (CO) 6-mm ferrule height without post, with a cervical cavity (access to root canal and cerv
