Crystal structures of penicillin-binding protein 6 from Escherichia coli.
Penicillin-binding protein 6 (PBP6) is one of the two main DD-carboxypeptidases in Escherichia coli, which are implicated in maturation of bacterial cell wall and formation of cell shape. Here, we report the first X-ray crystal structures of PBP6, capturing its apo state (2.1 A), an acyl-enzyme intermediate with the antibiotic ampicillin (1.8 A), and for the first time for a PBP, a preacylation...
متن کاملThe Location of the Photoperiodic Receptors in the Aphid Megoura Viciae Buckton.
Although the photoperiodic reactions of insects and mites have been studied quite extensively (Lees, 1955; de Wilde, 1962), the site of the photoreceptors is still unknown. The light pathway does not seem to involve the eyes. Thus Tanaka (1950) observed that the photoperiodic control of diapause in the silkworm Antheraea pernyi was not affected by cauterizing the lateral ocelli of the 4th-insta...
متن کاملRole of the aphid species and their feeding locations in parasitization behavior of Aphelinus abdominalis, a parasitoid of the lettuce aphid Nasonovia ribisnigri
Aphid species feeding on lettuce occupy distinct feeding sites: the lettuce aphid Nasonovia ribisnigri prefers to feed on heart leaves, whereas the potato aphid Macrosiphum euphorbiae feeds only on outer leaves. The aphid parasitoid Aphelinus abdominalis, known to be able to regulate M. euphorbiae on many crops, has recently been indicated as a promising biocontrol candidate also for use agains...
متن کاملThe Organization of Flight Muscle in an Aphid, Megoura Viciae (homoptera)
The organization of the indirect flight muscle of an aphid (Hemiptera-Homoptera) is described. The fibers of this muscle contain an extensive though irregularly disposed complement of T system tubules, derived as open invaginations from the cell surface and from the plasma membrane sheaths accompanying the tracheoles within the fiber. The sarcoplasmic reticulum is reduced to small vesicles appl...
متن کاملOdorant binding and conformational changes of a rat odorant-binding protein.
Odorant-binding proteins (OBPs) are lipocalins secreted in the nasal mucus of vertebrates, which convey odorants to their neuronal receptors. We compared the binding properties of a recombinant rat OBP (OBP-1F) using a set of six odorants of various chemical structures. We examined the binding properties by both fluorescent probe competition and isothermal titration calorimetry. OBP-1F affinity...
