Abstract
Avian infectious bronchitis virus grown in ovo was purified by differential centrifugation and isopycnic sedimentation in density gradients. The purified virus was analysed by SDS polyacrylamide gel electrophoresis and found to comprise up to sixteen polypeptides, four of which were glycopeptides. Bromelain treatment of the particles removed three polypeptides and two glycopeptides.

Abstract
Three morphologically distinct structures, inner core, envelope, and surface projections, were observed in purified Japanese encephalitis virus virions by electron microscopy. The average diameter of each structure was 29.8 +/- 2.5, 44.8 +/- 3.2, and 53.1 +/- 4.5 nm, respectively. Double staining with uranyl acetate and phosphotungstic acid preserved these structures well. Treatment of virions with proteolytic enzymes resulted in the loss of hemagglutinating activity, surface projections, and the major polypeptide band in polyacrylamide gel electrophoresis, which corresponds to glycoprotein, one of the three virion polypeptides. Surface projections were purified by cesium chloride density gradient centrifugation after treatment of virions with Nonidet P-40. The purified materials had a density of 1.256 g/cm(3) and were composed of only glycoprotein, as revealed by polyacrylamide gel electrophoresis. Purified surface projections carried hemagglutinating activity, as well as neutralizing antibody-blocking activity, and induced neutralizing antibody in mice.

Abstract
Analysis of the protein composition of tomato spotted wilt virus (TSWV), purified by an improved procedure, by polacrylamide gel electrophoresis, revealed three major structural proteins (of MW 84,000, 50,000, and 29,000d) and a minor one of MW 220,000d. The three major proteins constitute about 98% of the total viral protein and all three were shown to be glycoproteins. One of the major proteins (MW 29,000d) and the minor protein were shown to be associated with subviral particles isolated by treatment of virus with the nonionic detergent Nonidet P-40. Only traces of the other two proteins were detected in the subviral particles. Synthesis of virus-induced proteins in TSWV-infected tobacco leaves was studied by labeling infected and healthy tissue with [3H]and [14C]valine, respectively. The labeled tissues were then fractionated into crude subcellular fractions and protein patterns of healthy and infected tissues were compared by coelectrophoresis on polyacrylamide gels. Only one virus-specific protein (of MW 49,000d) was detected in the virus-enriched fractions; this corresponded with the viral structural protein of MW 50,000d.

Abstract
Influenza B/LEE/40, B/Rome/1/67, B/Hong Kong/8/73, and B/Victoria/98926/70 viruses have a similar polypeptide composition as analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis. These viruses are composed of six or seven polypeptides, depending on whether one or two high-molecular-weight polypeptides are resolved, ranging in molecular weights from 27,000 to 90,400. Three of these polypeptides, namely the heavy and light hemagglutinin chains and the neuraminidase, have attached carbohydrate. Highly purified influenza B/LEE/40 and B/Rome/1/67 virus preparations have RNA-dependent RNA polymerase activity equivalent to the incorporation of 100 and 30 pmol, respectively, of (3)H-UMP per mg of virus protein per h at 37 C, which is demonstrated only in detergent-treated virus suspensions. However, no RNA-dependent DNA polymerase enzyme activity was detected in the two viruses although virus suspensions were "activated" by heat, alpha-chymotrypsin, and detergents. Other enzymatic activities were associated with purified preparations of influenza B virus and were attributed to minor contamination of virus with host cell enzymes. Thus, nucleoside and deoxynucleoside phosphohydrolase enzymes were active in the absence of detergents and catalyzed the release of 1,200 and 1,800 nmol of P(i) per mg of virus protein in 30 min at 37 C from ATP and dATP substrates. Thin-layer chromatography indicated that the products of the phosphohydrolase enzymes of influenza B/LEE/40 were mainly nucleoside diphosphate and monophosphate. The latter enzymes were tightly bound to influenza B/LEE/40 virus and could not be removed completely by repeated centrifugation, including centrifugation of the virus to equilibrium in density gradients of 25 to 40% (wt/vol) cesium chloride. A low degree of RNase (approximately 0.01 mug% contamination) and phosphatase (10-30 nmol of P(i) released per mg of virus protein per 30 min) activity was detected in some, but not all, influenza B/LEE/40 virus preparations.

Abstract
Structures with RNA polymerase activity were isolated from influenza virus-infected cells, and consisted of ribonucleoprotein (RNP) complexes, similar in morphology to the viral internal component or nucleocapsid. The isolation procedure involved fractionation of infected cells in a discontinuous sucrose gradient, in which enzyme activity was concentrated in a fraction of intermediate density which contains both smooth and rough cytoplasmic membranes. The RNPs with polymerase activity were further purified in a velocity gradient, after which the peak fractions showed a 35-fold purification of the polymerase activity when compared with cytoplasmic extracts. The NP polypeptide, which is the subunit of the virion RNP, was the only virus-specific polypeptide detected in these RNP structures.

Abstract
This chapter discusses lipids in viruses. Lipid forms an integral part of many viruses and exists either in the form of a continuous envelope or in lipoprotein complexes that surround a nucleoprotein core or helix. In general, the envelope can be described as a molecular container for the genetic material of the virus. Viruses are obligate intracellular parasites and are not known to carry genetic coding for enzymes involved in lipid synthesis. Hence, they generally contain the same classes of lipid as are found in the host cell or their membrane of assembly. Lipids make up 20–35% by weight of most viruses; however, there are exceptions such as vaccinia virus, which has only 5% lipid despite having a complex multimembrane envelope structure. Naked herpesvirus capsids closely resemble non-lipid-containing viruses such as adenovirus or polyoma virus, which are also assembled in the nucleus but show full infectivity without any envelope. Both naked and enveloped herpesvirus particles are found in infected cells; however, only enveloped particles are found in extracellular fluids.

Abstract
The virion ribonucleic acid (RNA) polymerase of influenza strain A(0)/WS transcribed at least 81% of the viral genome in vitro. The polymerase is shown to be associated with each of the major size classes of the virion RNA-ribonucleoprotein complexes. Under optimal in vitro conditions, at least 45% of the RNA contained in a population of influenza virions was involved in a repetitive transcription process. The detectable proteins associated with enzymatically active complexes containing RNA, ribonucleoprotein, and polymerase have been identified by polyacrylamide gel electrophoresis.
