FhuA-mediated phage genome transfer into liposomes: A cryo-electron tomography study (2001)

Böhm, J., Lambert, O., Frangakis, A. S., Letellier, L., Baumeister, W., Rigaud, J. L.

Background: The transfer of phage genomes into host cells is a well established but only dimly understood process. Following the irreversible phage binding to a receptor in the bacterial outer...

Grain Boundary Segregation in Nickel Base Superalloys Astroloy: An Atom-Probe Study. (1998)

Letellier, L., Chambreland, S., Duval, P., Blavette, D.

Two types of grain boundaries, straight and serrated, of the Ni-based alloy, Astroloy, are examined in this paper. The properties are studied by means of TEM and atom-probe techniques.

Mode of action of nisin Z against Listeria monocytogenes Scott A grown at high and low temperatures. (1994)

Abee, T., Rombouts, F.M., Hugenholtz, J., Guihard, G., Letellier, L.

Nisin Z, a natural nisin variant, was recently isolated from Lactococcus lactis subspecies lactis NIZO 22186. The gene for this lantibiotic, designated nisZ, has been cloned, and its nucleotide...

Kinetic studies of the action of Lactacin F, a bacteriocin produced by Lactobacillus johnsonii that forms poration complexes in the cytoplasmic membrane. (1994)

Abee, T., Klaenhammer, T.R., Letellier, L.

The bacteriocin lactacin F is bactericidal against Lactobacillus delbrueckii, Lactobacillus helveticus, and Enterococcus faecalis. Activity against L. delbrueckii was recently shown to be dependent...

Role of acidic lipids in the translocation and channel activity of colicins A and N in Escherichia coli cells (1993)

Van Der Goot, F. G., Didat, N., Pattus, F., Dowhan, W., Letellier, L.

Colicins A and N are pore-forming bacterial toxins that kill Escherichia coli cells. Their mode of action involves three steps; binding to specific receptors located in the outer membrane,...

Structure-activity analysis of thanatin, a 21-residue inducible insect defense peptide with sequence homology to frog skin antimicrobial peptides.

Fehlbaum, P, Bulet, P, Chernysh, S, Briand, J P, Roussel, J P, Letellier, L, ...

Immune challenge to the insect Podisus maculiventris induces synthesis of a 21-residue peptide with sequence homology to frog skin antimicrobial peptides of the brevinin family. The insect and frog...

In vivo properties of colicin A: channel activity is voltage dependent but translocation may be voltage independent.

Bourdineaud, J P, Boulanger, P, Lazdunski, C, Letellier, L

The kinetics of K+ efflux caused by colicin A in Escherichia coli-sensitive cells have been investigated by using a K(+)-selective electrode. The order of magnitude of the rate of K+ efflux per...

Quantification of group A colicin import sites.

Duché, D, Letellier, L, Géli, V, Bénédetti, H, Baty, D

Pore-forming colicins are soluble bacteriocins which form voltage-gated ion channels in the inner membrane of Escherichia coli. To reach their target, these colicins first bind to a receptor located...

Kinetic studies of the action of lactacin F, a bacteriocin produced by Lactobacillus johnsonii that forms poration complexes in the cytoplasmic membrane.

Abee, T, Klaenhammer, T R, Letellier, L

The bacteriocin lactacin F is bactericidal against Lactobacillus delbrueckii, Lactobacillus helveticus, and Enterococcus faecalis. Activity against L. delbrueckii was recently shown to be dependent...

Release of respiratory control in Escherichia coli after bacteriophage adsorption: process independent of DNA injection.

Letellier, L, Labedan, B

Adsorption of phages T4, T5, and BF23 to previously starved Escherichia coli cells triggered the immediate release of respiratory control. A similar stimulation of respiration was induced after T4...

Involvement of envelope-bound calcium in the transient depolarization of the Escherichia coli cytoplasmic membrane induced by bacteriophage T4 and T5 adsorption.

Letellier, L, Labedan, B

We previously showed that adsorption of bacteriophages T4 and T5 to their respective outer membrane receptors induced a partial depolarization of the cytoplasmic membrane. As these membrane potential...

Depolarization-induced Ca2+ increase in isolated neurosecretory nerve terminals measured with fura-2.

Brethes, D, Dayanithi, G, Letellier, L, Nordmann, J J

The free Ca2+ concentration in isolated rat neurohypophysial nerve endings was measured using the Ca2+ indicator fura-2. Depolarization with high K, veratridine, or electrical stimulation induced an...

Membrane potential changes during the first steps of coliphage infection.

Labedan, B, Letellier, L

Immediately after adsorption, phages T4 and T5 induce a partial depolarization of the host cytoplasmic membrane. Infected bacteria respond to this phage-induced effect by a repolarization that leads...

Lipid and protein segregation in Escherichia coli membrane: morphological and structural study of different cytoplasmic membrane fractions.

Letellier, L, Moudden, H, Shechter, E

Lipid and protein segregations can be induced in E. coli cytoplasmic membranes by conformational transitions of their lipid hydrocarbon chains from a disordered to an ordered state. For E. coli...

FhuA, a transporter of the Escherichia coli outer membrane, is converted into a channel upon binding of bacteriophage T5.

Bonhivers, M, Ghazi, A, Boulanger, P, Letellier, L

The Escherichia coli outer membrane protein FhuA catalyzes the transport of Fe3+(-)ferrichrome and is the receptor of phage T5 and phi 80. The purified protein inserted into planar lipid bilayers...

Colicin A unfolds during its translocation in Escherichia coli cells and spans the whole cell envelope when its pore has formed.

Bénédetti, H, Lloubès, R, Lazdunski, C, Letellier, L

The addition of the pore forming colicin A to Escherichia coli cells results in an efflux of cytoplasmic potassium. This efflux is preceded by a lag time which is related to the time needed for the...

Androctonin, a hydrophilic disulphide-bridged non-haemolytic anti-microbial peptide: a plausible mode of action.

Hetru, C, Letellier, L, Oren, Z, Hoffmann, J A, Shai, Y

Androctonin is a 25-residue non-haemolytic anti-microbial peptide isolated from the scorpion Androctonus australis and contains two disulphide bridges. Androctonin is different from known native...
