Abstract
Phage phi29 is a nonisometric virus producing several types of morphological variants in normal infections. The study of these variants by electron microscopy, and their comparison with those from T-even phages, suggest that the capsid of phage phi29 is a prolate icosahedron. Phage phi29 capsid consists of a major protein, p8, and an additional protein, p8.5, making up the fibers. We have determined the number of subunits of each structural protein per viral particle taking into account the phage molecular weight (between 28 and 29.6 x 10(6)), the molecular weight of each structural protein, and the mass percentage of each protein with respect to the total protein mass of the phage. These values, together with the results obtained from chemical crosslinking of the structural proteins on the phage, suggest that the capsid contains protein p8 dimers clustered in trimers.

Abstract
Dystrophin is purified as a complex with several proteins from the digitonin-solubilized muscle cell membrane. Most of dystrophin-associated proteins (DAPs) are assumed to form a large oligomeric transmembranous glycoprotein complex on the sarcolemma and link dystrophin with a basement membrane protein, laminin. In the present study, we found that the purified dystrophin-DAP complex was dissociated into several groups by n-octyl-beta-D-glucoside treatment. In particular, we found that the glycoprotein complex stated above was dissociated into two distinct groups: one composed of 156DAG and 43DAG (A3a) and the other composed of 50DAG, 35DAG and A3b. We confirmed by crosslinking and immunoaffinity chromatography that these two groups existed in a complexes. We thus concluded that the glycoprotein complex consists of these two subcomplexes. Furthermore, A3b and 43DAG, which had been formerly treated simply as the 43DAG doublets due to their similar electrophoretic mobilities in SDS/PAGE, were shown to be present in two different subcomplexes. Based on the analyses by two-dimensional gel electrophoresis, peptide mapping and immunoblotting, we concluded that A3b is a novel DAP different from 43DAG.

Abstract
Hepatocyte growth factor (HGF) is a heparin-binding polypeptide mitogen for a variety of cell types including hepatocytes. HGF also has cytotoxic activity on some tumor cell lines as well as scattering activity on epithelial cells. In this study, recombinant human HGF was used to identify HGF-binding cell surface receptors on Meth A cells, whose growth is inhibited by HGF. Scatchard analysis of binding data indicated that there were two classes of binding sites with high affinity (Kd = 17 pM) and low affinity (Kd = 6.7 nM) and the average numbers were 6600 and 2,600,000 per cell, respectively. Affinity cross-linking of 125I-HGF to Meth A cells resulted in a major and a minor specifically labeled complex. Competition analysis followed by cross-linking indicated that the HGF-binding proteins were involved in the formation of the high-affinity binding. The existence of the two HGF-binding surface proteins was confirmed by HGF-dependent immunoprecipitation of the binding proteins with an anti-HGF polyclonal antibody. The molecular masses of the major and the minor surface proteins were 160 kDa and 130 kDa, respectively. The 160-kDa protein was autophosphorylated in vitro on tyrosine residue and was immunoprecipitated with an antiserum against the c-met proto-oncogene product. These results indicate that the 160-kDa HGF-binding surface protein on Meth A cells is the c-met protein. Furthermore, tyrosine phosphorylation of the c-met protein was stimulated by HGF treatment of Meth A cells, suggesting that it may be involved in the signal transduction of the growth inhibition of Meth A cells by HGF.

Abstract
Three complementary two-dimensional systems for the analysis of cereal prolamins are described. These are electrophoresis at pH 3.1 followed by electrophoresis at pH 9.2, isoelectric focusing (IEF) followed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and SDS-PAGE under non-reducing conditions followed by SDS-PAGE with reduction. They together give information on the pIs, Mrs and charge properties of the individual prolamin components, and on their interactions to form oligomers stabilized by inter-chain disulphide bonds. The three systems are then compared for their effectiveness in analysing unreduced prolamin I fractions from wheat and rye, and the IEF/SDS-PAGE system for analysing reduced and pyridylethylated prolamin fractions from all the major cereals. Finally, applications of the systems in biochemical and genetic studies are discussed and illustrated with three examples: analysis of the structural relationships of the S-rich prolamins (B hordeins and gamma-type hordeins) of barley, determination of the interactions of wheat and rye prolamin subunits in a 2RS/2BL translocation line, and the mapping of genes for alpha-type prolamins in the wild grass Haynaldia villosa.

Abstract
The reversible crosslinked protein complex L13-L21 was isolated from Escherichia coli ribosomes in milligram amounts. Tight couples (70 S) were crosslinked with the bifunctional reagent diepoxybutane. The reacted ribosomes were separated into their subunits by sucrose gradient centrifugation in the presence of 1 mM magnesium. The crosslinked subunits were analyzed by symmetrical two-dimensional gel electrophoresis. One crosslinked protein complex detected within the large subunit was purified by salt extraction, acidic acid extraction, and ion-exchange chromatography. Two-dimensional gel electrophoresis and immunological results established L13 and L21 as the components of this crosslink.

Abstract
Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) of unreduced total protein extracts from the endosperm of hexaploid wheat revealed three high molecular weight protein bands (triplet bands) in a zone of heavy background streaking. Electrophoretic examination of 135 hexaploid cultivars showed at least five different patterns of these triplet bands. Nine durum wheat cultivars showed a single band only. Analysis of nullisomic-tetrasomic and ditelocentric lines of 'Chinese Spring' wheat revealed that the slowest moving band (Tri-1) of the triplet was controlled by gene(s) on chromosome arm 1DS and the fastest moving band (Tri-3) by 1AS. The band with intermediate mobility (Tri-2) was found to be a hybrid aggregate of the subunits controlled by 1DS and 1AS. Using a non-reducing/reducing form of 2-dimensional (2-D) electrophoresis, these triplet bands were shown to be heterotetramers of four subunits designated D (M.W. 58,000), δ (22,000), A (52,000) and α (23,000) where Tri-1=DδDδ, Tri-2 = DδAα and Tri-3 = AαAα. With very low concentrations of 2-mercaptoethanol (ME), the tetramers dissociated into dimeric subunit pairs (Dδ, Aα), the monomers being observed with higher concentrations of ME. The structure of these subunit pairs resembles that of the subunit pairs in the globulin storage proteins of oats and some legumes. The 2-D method employed in this study was useful also for separating low molecular weight (LMW) subunits of glutenin from the monomeric gliadins which have similar electrophoretic mobility in 1-D separation. It was shown that at least four of these LMW glutenin subunits are controlled by genes on 1DS and 1AS and at least one subunit is controlled by gene(s) on 1BS. This electrophoretic separation method has proven useful in understanding the aggregation behaviour of the seed proteins of wheat.

Abstract
Using a mild iodination method for protein radioactive labeling, it has been shown that elongation factor G, when bound to the ribosome as EFG-GDP-fusidic acid complex, protects protein S4 from labeling. The results indicate that protein S4 is probably near the ribosomal EFG binding site.

Abstract
The reactivity of protein S4-specific antibody preparations with 30 S ribosomal subunits and intermediates of in vitro subunit reconstitution has been characterized using a quantitative antibody binding assay. Anti-S4 antibody preparations did not react with native 30 S ribosomal subunits; however, they did react with various subunit assembly intermediates that lacked proteins S5 and S12. The inclusion of proteins S5 and S12 in reconstituted particles resulted in a large decrease in anti-S4 reactivity, and it was concluded that proteins S5 and S12 are primarily responsible for the masking of S4 antigenic determinants in the 30 S subunit. The effect of S5 and S12 on S4 accessibility is consistent with data from a variety of other approaches, suggesting that these proteins form a structural and functional domain in the small ribosomal subunit.

Abstract
The location of protein S4 in the small ribosomal subunit has been identified by immunoelectron microscopy. Although intact small subunits are not reactive with antibodies directed against protein S4, subribosomal particles reconstituted without proteins S5 and S12 are reactive. By using these "incomplete" subparticles, we have mapped the position of S4. It is located at a single site on the exterior (cytoplasmic) side of the subunit, at the partition that separates the one-third, or head, from two-thirds, or base, of the subunit. In this location, protein S4 is "beneath" proteins S5 and S12. All three proteins are members of a complex on, or near, the external surface of the small ribosomal subunit that plays an important role in regulation of translational fidelity.

Abstract
Flash irradiation of the reconstituted troponin of thin filament complex in which one of their components, troponin C, was modified with a heterobifunctional photosensitive reagent before reconstitution of the troponin complex resulted in the formation of cross-links between troponin C and other components in contact with it. Quantitative analysis of the cross-linked products by gel electrophoresis has revealed interesting features of the quaternary structure of troponin. When the reconstituted troponin was photo-cross-linked with a xenon flash, an appreciable amount of cross-linking was detected between troponin C and troponin I and also between troponin C and troponin T. No effect of calcium on the cross-linking could be detected. This arrangement of components was found to change when troponin was complexed with F-actin-tropomyosin. The arrangement of troponin components in the thin filament complex was sensitive to calcium and magnesium; maximum cross-linking of troponin C and troponin I was observed when the thin filament was cross-linked in the presence of calcium and magnesium, while an appreciable decrease in the extent of the cross-linking was detected when calcium alone or calcium and magnesium were removed from the cross-linking medium. The cross-linking of troponin C and troponin T remained marginal irrespective of the concentration of calcium and magnesium.

Abstract
This topographical model of the proteins of the 30 S subunit of the Escherichia coli ribosome was built to be consistent with the 37 published spectroscopic and chemical experiments that indicate proximity and with the two neutron diffraction experiments that indicate S3 and S7 as well as S2 and S5 to be separated by 110 A. The model is quite consistent with the protein arrangement suggested by assembly pathways, the various RNA binding sites, and the streptomycin-associated proteins, This consistency is encouraging since none of these data were considered during the construction of the model. The model differs significantly from those proposed by Traut et at. ((1974) Ribosomes 271-308) and by Tischendorf et al. ((1975) Proc. Natl. Acad. Sei. U.S. 72, 4820-4824).

Abstract
A component of the high-affinity histidine transport system in Salmonella typhimurium, the periplasmic histidine-binding protein J, interacts with another transport component, the P protein. A mutant J protein, with a defective interaction site but intact histidine-binding site, can function in histidine transport if an appropriate compensating mutation is introduced in the P protein. The interaction between the J and P proteins is an obligatory step in transport. The significance of this interaction and of the involvement of the P protein in multiple transport functions is discussed.
