Daou, Dania. "Intégration de moteurs moléculaires photoactivables dans des gels supramoléculaires." Electronic Thesis or Diss., Strasbourg, 2024. http://www.theses.fr/2024STRAF021.
Full textThis thesis explored the integration of light-driven synthetic molecular motors in supramolecular gel networks. The main goal was to achieve reversible macroscopic motion by exploiting both the unidirectional rotation of molecular motors and the reversible nature of supramolecular interactions. Highly functionalized molecular motors have been synthesized and integrated as crosslinking units in supramolecular gel networks of diphenylalanine and poly(γ- benzyl-L-glutamate) peptides, as well as DNA oligonucleotides. Activation of the unidirectional rotation of molecular motors by light, allowed the production of nanomechanical work which is sufficient to disrupt supramolecular interactions in peptide-based gel networks leading to contraction or melting of the gel material at the macroscopic scale. Thanks to the reversible supramolecular interactions, the initial gel material was recovered in the dark, either spontaneously or by applying a thermal stimulus. The systems studied in this thesis represent a novel class of materials operating in dissipative out-of-equilibrium conditions, holding promise of applications in various fields such as biology, medicine and material science

Full textThe nanometric field raises a lot of questions. One of them concerns molecular motors. Is it possible to design a device capable of moving itself inside an environment ? If so how can we characterise its motion ? Does it influence the environment ? Does the environment influence the motor’s motion ? We took an interest here to the study of several parameters such as the ratio of the motor’s relative length to the environment’s molecule length, the ratio of the motor’s relative mass to the environment’s molecule mass, the motor’s folding frequency, thetemperature’s influence, the motor’s orientation, the different time configurations. We showed that the motor’s relative length ratio to the environment’s molecule length, as well as the motor’s relative mass ratio to the environment’s molecule mass, have an influence on the motor’s displacement. Every motor presenting one hinge, is subject to the scallop theorem introduced by E.M. Purcell. We found a way to break this theorem by playing on the motor’s folding frequency. Then we altered our motor in order for it to possess to hinges. We studied the effect of different time configuration on the motor’s displacement. Finally we wanted to give a privileged direction to our motor by submitting it to an electrical field

Full textCilia are evolutionary conserved and ultra-specialized cell differentiations. Primary ciliary dyskinesia (PCD) are rare autosomal recessive respiratory disorders, due to abnormalities of motile cilia. PCD are associated in ~50% of the cases with situs inversus. A detailed update is made on the components (microtubule doublets, dynein arms, radial spokes, central complex) of the cytoskeleton (the 9 +2 axoneme) of the motile cilia. To date, mutations of 24 genes explain the disease in half of the patients with PCD from the National Center for Rare Respiratory Diseases cohort (313 independent families), on which the work was focused. The goal was to progress in the molecular etiology of PCD. The approaches, combining candidate-genes approach, homozygosity mapping and whole exome sequencing in six independent families, allowed us to involve three new genes: (i) in PCD without dynein arms, LRRC6, which plays a role in the pre-assembly of these structures; (ii) in PCD associated with central complex abnormalities, RSPH1 and HYDIN, which encode a protein of the radial spoke head and a protein of the axoneme central sheath, respectively. The identification of new PCD genes allows the establishment of a definitive diagnosis of PCD, improves genetic counseling and therapeutic care, and also enables a better understanding of the mechanisms involved in the proper building and function of motile cilia in humans

Full textThe development of molecular machines is a topic of current interest. The main challenge in this area is to impose the directionality of the movement. Also, the aim of this thesis is the development of new porphyrins based rotary molecular machines bearing at their periphery different recognition sites. In a first part, we describe the synthesis and the study, mainly by NMR spectroscopy, of several tin (IV) handle-porphyrin based molecular turnstiles. The “opened” and “closed” states are characterized and different studies dealing with the “opening-closing” process and the switch between one station to another are performed and discussed. In the second part, we introduce a new type of motor based on bridged-porphyrin. In this case, the rotor is directly attached through a covalent bond to the porphyrin backbone. This type of architectures is developed in order to avoid the collapse of the system due to the low stability of the Sn-O bond in acidic media. Different bridged porphyrins were synthesized and, as for the molecular turnstiles, different “opened” and “closed” states could be reached and characterized

Full textMicrotubules (MTs) are cytoskeletal filaments that are essential for many different cellular functions including cell division, intracellular transport and cell motility. Polyglutamylation is a post-translational modification that targets alpha- and beta-tubulin, the building blocks of MTs. This modification is present on the C-terminal tail of the tubulins, which is a main domain of interaction between MTs and MAPs (MTs associated proteins). Tubulin polyglutamylation is a complex modification that can generate long side chains of glutamates on a single modified residue of the protein. My first focus was to characterize the enzymatic properties of the polyglutamylases of the family of TTLLs (Tubulin Tyrosine Ligase Like proteins). I found that each enzyme has a specificity toward initiation or elongation of the side chains and for preferentially modifying alpha or beta tubulin. The polyglutamylation level on MTs varies during the cell cycle: interphase MTs are almost not glutamylated whereas spindle and midbody MTs are strongly modified. This suggests that tubulin polyglutamylation plays a specific role during mitosis. I demonstrated that the glutamylation pattern present on mitotic MTs regulates the localisation and activity of MAPs. I found that the mitotic MAP (TPX2) is recruited specifically to glutamylated MTs and that polyglutamylated tubulin activates the MT-severing activity of two proteins, katanin and spastin
