Full textCette prédiction se base avec une méthode bayésienne qui permet de comprendre l'importance des acides aminés de maniè;re simple. Pour améliorer cette prédiction, nous nous sommes bases sur deux concepts : (i) 1 repliement local -> n séquences et (ii) 1 séquence -> n repliements. Le premier concept signifie que plusieurs types de séquences peuvent être associes a la même structure et le second qu'une séquence peut-être associée a plusieurs type de repliements. Ces deux aspects sont développés en se basant sur la recherche d'un indice de fiabilité lie a la prédiction locale, pour trouver des zones de fortes probabilités. Certains mots, i.e. successions de blocs protéiques apparaissent plus fréquemment que d'autres. Nous avons donc défini au mieux quelle est l'architecture de ces successions, les liens existants entre ces différents mots.
Du fait de cette redondance qui peut apparaìtre dans la structure protéique, une méthode de compactage qui permet d'associer des structures structurellement proches sur le plan local a été mise au point. Cette approche appelée "protéine hybride" de conception simple permet de catégoriser en classes "structurellement dépendantes" l'ensemble des structures de la base de données protéiques. Cette approche, en plus du compactage, peut être utilisée dans une optique différente, celle de la recherche d'homologie structurale et de la caractérisation des dépendances entre structures et séquences.

Full textI based my work on a representation of proteins developed in the laboratory: the structural alphabet of Protein Blocks (PBs). This alphabet is used to describe and study the local conformations of protein structures. With this representation I have firstly studied the structural irregularities observed in the 13 sheets, the β-bulges. They are described in the literature as conserved among protein families and impacting the structure and function of proteins. I tried to answer the question: are the β-bulges actually conserved within homologs folds? In a second time, I studied the post-translational modifications (PTMs), which essentially correspond to very different modifications of the protein residues. These PTMs are increasingly studied in the structural context, and their impact on the flexibility is more pointed. I have developed a database that curates the structures containing annotated modifications as PTMs. With this data I have tried to answer the question: Did the PTMs affect protein structure? This effect is global or local in protein structure? Finally in the last part of my thesis, I studied the correlation between local conformations and flexibility of the polypeptide backbone. Through numerous molecular dynamics simulations, I have attempted to quantify this correlation, systematically, and in view of the presence of β-bulges and PTMs sites. These works bring a new look on the prediction method developed in the laboratory flexibility

Full textFor structure calculation, the main source of information from Nuclear Magnetic Resonance (NMR experiments is the Nuclear Overhauser Effects (NOEs), which provide information about the distance between some protons of the molecule studied. The ARIA software package (for "Ambiguous Restraints for Iterative Assignment") is used to analyse and interpret NMR data, to determine a set of three-dimensional structures consistent with experimental data. ARIA uses the above measures in the form of distance constraints imposed, in silico, on the molecule. To impose these distances, the software used so far the "Soft Square" potential which presents a window of tolerance around the target distance measured experimental in order to take into account the uncertainties on the experimental data. A Recent analysis has shown the NOE errors follow a log-normal distribution, suggesting the use of a new log-harmonic potential. The aim of my thesis has been to show the effectiveness of the log-harmonic potential in improving the quality of structures determined by NMR. The first part of my thesis focuses on studying the behaviour of the potential with some examples of structures well known and whose data have been manually prepared. In second part, the recalculation of 398 NMR structures has demonstrated the overall improvement of the qualit of structures calculated with the log-harmonic potential. Finally, in a third part, the study of two protein allowed identifying the properties of the log-harmonic potential for error detection in structures

Full textBackground. Few high-resolution structures of integral membranes proteins are available, as crystallization of such proteins needs yet to overcome too many technical limitations. Nevertheless, prediction oftheir transmembrane (TM) structure by bioinformatics tools provides interesting insights on the topology of these proteins.Method. We describe here how to extract new information from the analysis of hydrophobicity variations or hydrophobic pulses (HPulses) in the sequence of integral membrane proteins using the Hydrophobic Pulse Predictor, a new tool we developed for this purpose. To analyze the primary sequence of 70 integralmembrane proteins we defined two levels of analysis : G1-HPulses for sliding windows of n=2 to 6 andG2-HPulses for sliding windows of n=12 to 16.Results. The G2-HPulse analysis of 541 transmembrane helices allowed the definition of the new conceptof transmembrane unit (TMU) that groups together transmembrane helices and segments with potentialadjacent structures. In addition, the G1-HPulse analysis identified helix irregularities that correspondedto kinks, partial helices or unannotated structural events. These irregularities could represent key dynamicelements that are alternatively activated depending on the channel status as illustrated by the crystalstructures of the lactose permease in different conformations. Our results open a new way in the understanding of transmembrane secondary structures : hydrophobicity through hydrophobic pulses stronglyimpacts on such embedded structures and is not confined to define the transmembrane status of aminoacids
