To be infectious, most of the viruses require viral envelope glycoprotein maturation by host cell endoproteases. In spite of the strong variability of primary sequences observed within different viral envelope glycoproteins, the endoproteolytical cleavage occurs mainly in a highly conserved domain at the carboxy terminus of the basic consensus sequence (Arg-X-Lys/Arg-Arg↓). The same consensus sequence is recognized by the kexin/subtilisin-like </span>serine proteinases (so called convertases) in many cellular substrates such as prohormones, proprotein of receptors, </span>plasma proteins<span><span>, growth factors and bacterial toxins. Therefore, several groups of investigators have evaluated the implication of convertases in viral envelope glycoprotein cleavage. Using the </span>vaccinia virus<span> overexpression system, furin was first shown to mediate the proteolytic maturation of both human immunodeficiency virus (HIV-1) and influenza virus envelope glycoproteins. </span></span></span>In vitro studies<span><span> demonstrated that purified convertases directly and specifically cleave viral envelope glycoproteins. Although these studies suggested the participation of several enzymes belonging to the convertases family, recent data suggest that other protease families may also participate in the HIV envelope glycoprotein processing. Their role in the physiological maturation process is still hypothetical and the molecular mechanism of the cleavage is not well documented. Crystallization of the hemagglutinin precursor (HA0) of influenza virus allowed further understanding of the </span>molecular interaction<span> between viral precursors and the cellular endoproteases. Furthermore, relationships between differential pathogenicity of influenza strains and their susceptibility to cleavage are molecularly funded. Here we review the most recent data and recent insights demonstrating the crucial role played by this activation step in virus infectivity<span>.

These fluctuations degrade the higher order diffraction data in a way that, if unrecognized, leads to erroneous conclusions regarding bilayer structure. Diffraction measurements at high instrumental resolution provide a measure of these fluctuations. In addition to providing better structural determination, this opens a new window on interactions between bilayers, so the experimental determination of interbilayer interaction parameters is reviewed briefly. We introduce a new structural correction based on fluctuations that has not been included in any previous studies. Updated measurements, such as for the area compressibility modulus, are used to provide adjustments to many of the literature values of structural quantities. Since the gel (</span><em>L</em><sub>β</sub>′) phase is valuable as a stepping stone for obtaining fluid phase results, a brief review is given of the lower temperature phases.

In mammals complex changes in the plasma membrane of the sperm cell are involved in this process. Sperm cells have unusual membranes compared to those of somatic cells. After leaving the testes, sperm cells cease plasma membrane lipid and </span>protein synthesis<span><span>, and vesicle mediated transport. Biophysical studies reveal that lipids and proteins are organized into lateral regions of the sperm head surface. A delicate reorientation and modification of plasma membrane molecules take place in the female tract when sperm cells are activated by so-called capacitation factors. These surface changes enable the sperm cell to bind to the extra cellular matrix of the egg (zona pellucida, ZP). The ZP primes the sperm cell to initiate the acrosome reaction, which is an exocytotic process that makes available the enzymatic machinery required for </span>sperm penetration through the ZP. After complete penetration the sperm cell meets the plasma membrane of the egg cell (oolemma). A specific set of molecules is involved in a disintegrin–integrin type of anchoring of the two </span></span>gametes which is completed by fusion of the two gamete plasma membranes. The fertilized egg is activated and zygote formation preludes the development of a new living organism. In this review we focus on the involvement of processes that occur at the sperm plasma membrane in the sequence of events that lead to successful fertilization. For this purpose, dynamics in adhesive and fusion properties, molecular composition and architecture of the sperm plasma membrane, as well as membrane derived signalling are reviewed.</p></div>","PeriodicalId":100168,"journal":{"name":"Biochimica et Biophysica Acta (BBA) - Reviews on Biomembranes","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0304-4157(00)00018-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21890955","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although differences in the biophysical properties of hydrophobins have not yet been related to differences in primary structure<span> it has been established that the N-terminal part, at least partly, determines wettability of the hydrophilic side of the assemblage, while the eight conserved cysteine residues that form four disulphide bridges prevent self-assembly of the hydrophobin in the absence of a hydrophilic–hydrophobic interface. Three conformations of class I hydrophobins have been identified: the monomeric state, which is soluble in water, the α-helical state, which is the result of self-assembly at a hydrophobic solid, and the β-sheet state, which is formed during self-assembly at the water–air interface. Experimental evidence strongly indicates that the α-helical state is an intermediate and that the β-sheet state is the end form of assembly.
