Structure and expression analysis of the cecropin-E gene from the silkworm, Bombyx mori. (1/14)

Cecropins belong to the antibacterial peptides family and are induced after injection of bacteria or their cell-wall components. By silkworm cDNA microarray analysis, a novel type of Cecropin family gene was identified as a cDNA up-regulated in early embryo, 1 day after oviposition. The cDNA isolated was 394 bp with 198 ORF translating 65 amino acids, encoding BmCecropin-E (BmCec-E). Using Southern hybridization and genome search analysis, the number of BmCec-E gene was estimated to be at least two per haploid, which consisted of two exons, as in other Cecropin family members. BmCec-E mRNA was expressed transiently 1 day after egg-laying (AEL, germ-band formation stage), and was specifically expressed in the degenerating intestine during the pre-pupal and pupal stages, unlike other Cecropin family genes. Immune challenge analysis showed that BmCec-E gene expression was more strongly induced by Escherichia coli (gram-negative) than by Micrococus luteus (gram-positive), and not by virus injection. By bacterial challenge, expression of BmCec-E mRNA was induced 12 h after injection, and was maintained for 24 h. Expression of BmCec-E after immune challenge was observed strongly in excretory organs, such as hindgut and malphigian, slightly in fat body, skin, and midgut.  (+info)

Anionic C-terminal proregion of nematode antimicrobial peptide cecropin P4 precursor inhibits antimicrobial activity of the mature peptide. (2/14)

Recently, an anionic proregion was found to be conserved at the C terminus of the antimicrobial peptide, nematode cecropin. Our results suggest that the antimicrobial activity of mature peptide is suppressed by the proregion in its precursor and is released from inhibition after processing. Inhibition is not likely to be due to direct suppression of membrane disruption.  (+info)

TY - JOUR. T1 - Improvement of outer membrane-permeabilizing and lipopolysaccharide- binding activities of an antimicrobial cationic peptide by C-terminal modification. AU - Piers, K. L.. AU - Brown, M. H.. AU - Hancock, Robert. PY - 1994/1/1. Y1 - 1994/1/1. N2 - Antimicrobial cationic peptides have been discovered in many different organisms and often possess a broad range of activity. In this study, we investigated the mechanisms of actions of melittin and two synthetic peptides, CEME (a cecropin-melittin hybrid) and CEMA, against gram-negative bacteria. CEMA was produced by recombinant DNA procedures and is an analog of CEME with a modified C terminus resulting in two additional positive charges. All three peptides showed good antimicrobial activity against four different gram-negative bacteria, but only CEMA was able to somewhat augment the activity of some conventional antibiotics in synergy studies. Studies using the bacteria Pseudomonas aeruginosa and Enterobacter cloacae showed that the ...

We suggest that both the multiplicity of AMPs and the specific mechanisms of action of the complex constituents are equally important for resistance prevention. C. vicina AMP complexcomprises four major cationic AMP families, which kill bacteria directly: defensins, cecropins,diptericins and proline-rich peptides. Calliphora defensin, as well as defensins of other insectsand vertebrates, is a peptide with a 3D structure containing α-helix/β-sheet elements coordi-nated by 3 disulfide bridges and is predominantly active against Gram-positive bacteria. Alldefensins cause bacterial cell wall disruption/permeabilization although inhibition of the cellwall biosynthesis was demonstrated as well [, ]. Calliphora cecropin is a linear amphi-pathic α-helical peptide particularly active towards Gram-negative bacteria. All insect cecro-pins are known to have pore-forming and cell membrane permeabilizing activity Calliphora diptericins are members of a glycine-rich AMP family selectively toxic to ...

Although substrate-specific CYP6B1 and CYP6B3 enzymes in Papilio polyxenes contribute to specialization on furanocoumarin-containing host plants, CYP6B4 and CYP6B17 enzymes in the polyphagous Papilio glaucus and Papilio canadensis have a broader range of substrates. Papilio multicaudatus, an oligophage with one furanocoumarin-containing host, is putatively ancestral to polyphagous Papilio species. Furanocoumarin-inducible CYP6B33-CYP6B37 and CYP6AB6 were characterized from this species. Heterologous expression of CYP6B33 revealed furanocoumarin metabolism resembling that of CYP6B4-CYP6B17 enzymes from P. glaucus and P. canadensis. Molecular models of CYP6B33 and CYP6B4 indicate that seven conserved aromatic side chains stabilize their hydrophobic catalytic sites and that a Lys484-Ser484 substitution enlarges the CYP6B4 active site pocket to increase the predicted distance between the substrate and reactive oxygen relative to CYP6B1. Loss of specialization in this lineage may have resulted from ...
Hybrid Peptide Design. Hydrogen Bonded Conformations in Peptides Containing the Stereochemically Constrained γ-Amino Acid Residue, Gabapentin
The mosquito has multiple lines of defense against invading pathogens, but the most potent is found in its blood, called hemolymph. Parasites migrate through the gut epithelium in order to escape the harsh digestive conditions of the gut lumen. Here they come into contact with the hemolymph. Two leucine-rich repeat (LRR) containing proteins, LRIM1 and APL1C, are essential for mosquito immune defense in this compartment. We recently found that these proteins circulate in the mosquito hemolymph in a disulfide-bonded multimeric complex [1]. If either LRIM1 or APL1C is knocked-down by RNAi, the entire complex is lost and parasite survival is increased. Before parasites are killed, the complement-like protein TEP1 is localized on their surface, marking them for destruction. The LRIM1/APL1C complex interacts with TEP1 and is required for its localization to parasites during midgut invasion. When the LRIM1/APL1C complex is knocked-down, TEP1 fails to localize and the invading parasites are not killed. ...

1D9M: NMR structural characterization of cecropin A(1-8) - magainin 2(1-12) and cecropin A (1-8) - melittin (1-12) hybrid peptides.
abstract = {During the development of Plasmodium sp. within the mosquito midgut, the parasite undergoes a series of developmental changes. The elongated ookinete migrates through the layers of the midgut where it forms the oocyst under the basal lamina. We demonstrate here that if Aedes aegypti or Anopheles gambiae, normally susceptible to Plasmodium gallinaceum and P. berghei, respectively, are immune activated by the injection of bacteria into the hemocoel, and subsequently are fed on an infectious bloodmeal, there is a significant reduction in the prevalence and mean intensity of infection of oocysts on the midgut. Only those mosquitoes immune activated prior to, or immediately after, parasite ingestion exhibit this reduction in parasite development. Mosquitoes immune activated 2-5 days after bloodfeeding show no differences in parasite burdens compared with naive controls. Northern analyses reveal that transcriptional activity for mosquito defensins is not detected in the whole bodies of Ae. ...

Many insect species have a well-developed visual system with the capacity to see colour, i.e. objects in their environment are discriminated by their spectral content. Butterflies are considered to be highly visual animals and are generally believed to possess colour vision. Nevertheless, definitive evidence for colour vision was only recently obtained for two papilionid species, the Japanese yellow swallowtail Papilio xuthus (Kinoshita et al., 1999) and the Australian orchard butterfly Papilio aegeus (Kelber and Pfaff, 1999). In the classical example of insect colour vision, the honeybee Apis mellifera, three photoreceptors form the standard set of photoreceptors underlying colour vision, with spectral sensitivities in the ultraviolet, blue and green, respectively (Menzel and Backhaus, 1989), corresponding well with the absorption spectra of three identified rhodopsins (Townson et al., 1998). These rhodopsins are assumed to be expressed in anatomically well-defined photoreceptors (Menzel and ...
Dear group, I have some H.papilio, a Dutch strain, which are blooming now. While I read on Thad Howards and the recent Veronica Reads books this species carries 2-3 flowers per scape, the first one of mine has 4 and 6 and a third scape is still growing; all the other bulbs have 2 or 3 scape emerging too. But the shape of flowers is different and they dont have those two wide tepals as shown on the photos on those books and from photos of all US folks, but they look rather like the cybister hybrid Lima. On the other hand, this hybrid isnt thought to be so vigorous, according on V.Read. I wonder if it is the true species or an hybrid now. The seller is a reputable source and the bulbs where extra large (28cm+ girt) and they also listed Lima among the hybrids, but papilio was listed separately. Last year I got a papilio and Lima from an Italian retail company, but I thought I had mixed the labels when I saw this flower. http://pacificbulbsociety.org/pbswiki/files/… Oh, BTW this photo ...
