Abstract
In order to detect the structural proteins linked with disulfide bonds, CIV was solubilized and electrophoresed under nonreducing conditions in the first dimension and then under reducing conditions in the second dimension. The viral polypeptides linked originally with disulfide bonds were separated into subunits. The complexes were trimers (P′50) or dimers (P60 and P10). The apparent molecular weights of P81, P53, and P49 changed significantly according to the composition of the lysis buffer used, suggesting that the differences in their molecular weights were due to conformational changes produced by reduction of their intramolecular disulfide bonds. Sulfhydryl-containing polypeptides (P′50-P50, P60, P100, and P33) were detected by N-[14C]ethylmaleimide, and the accessibility of these residues was analyzed after successive stripping of the CIV particle. Radioiodination of external polypeptides by [125I]iodosulfanilic acid shows only one intensively labeled spot corresponding to the P50 polypeptide, whereas P′50 was only slightly labeled. Six viral polypeptides P81, P60, P31, P17, P13, and P10 were revealed to possess high affinity for CIV DNA. A structural model of CIV is proposed and discussed.

Abstract
Analytical procedures are elaborated for the sequential allotment of azobenzene arsonate binding sites in proteins and peptides. The reaction of diazotized arsanilic acid with proteins leads to covalent modification of tyrosine, histidine and, in part, lysine residues. Synthetic peptides containing these amino acids were modified with diazotized arsanilic acid and subjected to N-terminal sequence analysis. The amino acid derivatives phenylthiohydantoin(Pth)-azobenzene-arsonate-tyrosine, Pth-azobenzene-arsonate-histidine, and alpha-Pth-epsilon-hydroxycaproic acid are recovered upon Edman degradation of selected peptides. Phenylthiohydantoins of modified and nonmodified amino acids are fully separated by reverse-phase HPLC on a Zorbax-PTH column. For identification purposes, phenylthiohydantoins of azobenzene arsonate-labeled amino acids have been synthetized. They are characterized with respect to spectral absorption characteristics and retention times on reverse-phase supports.

Abstract
We investigated the effect of membrane splitting on the primary structure of human erythrocyte membrane polypeptides. Monolayers of intact, chemically unmodified cells were freeze-fractured and examined by one-dimensional SDS PAGE. Silver-stained gels revealed all major polypeptides that stain with Coomassie Blue as well as all bands that stain with periodic acid Schiff's reagent. Both nonglycosylated and glycosylated membrane polypeptides could be detected at concentrations of only a few nanograms per band. Membrane splitting had no effect on the position or number of bands. Monolayers of intact erythrocytes that had been enzymatically radioiodinated with lactoperoxidase were examined by electrophoresis, fluorography, and liquid scintillation counting. Radioactivity was quantified before and after monolayer formation and splitting, and at several stages of gel staining, drying, and fluorography. Although overexposed fluorographs revealed several minor radioiodinated bands in addition to band 3 and the glycophorins, no new bands were detected in split membrane samples derived from intact cells. These observations support the conclusion that neither the band 3 anion channel nor the glycophorin sialoglycoproteins are fragmented during freeze-fracturing. Although both band 3 and glycophorin partition to the cytoplasmic side of the membrane, preliminary quantitative observations suggest an enrichment of glycophorin in the split extracellular "half" membrane. We conclude that the process of membrane splitting by planar monolayer freeze-fracture does not cleave the covalent polypeptide backbone of any erythrocyte membrane protein, peripheral or integral.

Abstract
Alpha 1-proteinase inhibitor (alpha 1-PI) has been prepared as a concentrate in quantities large enough for clinical testing of its safety and efficacy in the treatment of emphysema and other disorders. The alpha 1-PI was purified from Cohn fraction IV-1 paste by polyethylene glycol precipitation and DEAE-Sepharose chromatography. The methods used in the purification are gentle and the resulting product behaves almost identically to the alpha 1-PI from plasma. The protein has been heat treated (60 degrees C, 10 h) to lower the risk of transmission of plasma-borne diseases. This resulted in some aggregation of the protein, but did not cause the generation of new antigenic sites. Half-life studies in animals showed that the protein behaved normally (catabolic t1/2 of 68 h).

Abstract
A developmentally regulated carbohydrate-binding protein from the capture organs of Arthrobotrys oligospora, not present on hyphae, was isolated and partially characterized. Surface structures of A. oligospora were radiolabeled with [125I]iodosulfanilic acid. The fungus was homogenized, and the homogenate was passed over an affinity column containing N-acetyl-D-galactosamine immobilized to Sepharose 6B. The bound radiolabeled protein was eluted from the affinity column with a glycine-hydrochloride buffer (pH 3.0), concentrated, and chromatographed on a metal chelate affinity gel containing Ca2+. EDTA was used as an eluant for the radiolabeled protein. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis in combination with autoradiography revealed a molecular weight for the carbohydrate- and cation-binding polypeptide of ca. 20,000.

Abstract
Porous membranes were fabricated from collodion and impregnated with papain, inhomogeneously through the thickness of the membrane. These membranes were placed between reservoirs containing N-alpha-benzoyl arginineamide, a substrate for the enzyme papain. The progress of the reaction was monitored by sampling the reservoirs on each side for ammonia, a reaction product. From these data the diffusion coefficient, enzyme activity, and distribution of enzyme activity of the membrane were estimated. The limitations of this approach are discussed in the context of the analysis of biological transport systems.

Abstract
Adult schistosomes have been labelled with 125I using the lactoperoxidase-catalysed technique modified to cause minimal worm damage. After surface membrane removal and characterization, at least 13 labelled proteins were identified together with a large amount of labelled glycolipids, free fatty acids and phospholipids, especially phosphatidyl ethanolamine. Cationised ferritin has been used to stimulate surface membrane turnover of iodinated worms and the shedding of covalently bound 125I-counts used as an index of turnover. Finally worms have been iodinated before and after stimulation of membrane turnover in chemically defined media and the patterns of labelled proteins were compared.

Abstract
1. The influence of various substances on the uptake of [3H]ATP and [14C]-noradrenaline into isolated bovine chromaffin granules was investigated. The carrier-mediated [3H]ATP uptake is specifically inhibited by SO42-, PO43- and phosphoenolpyruvate. Compounds with carboxylic acid or sulphonic acid groups had no significant inhibitory effects on either uptake. 2. 35SO42-, 32PO43- and phosphoenol[14C]pyruvate are taken up into chromaffin granules by a temperature-dependent process that is inhibited by atractyloside, uncouplers of oxidative phosphorylation and lipid-permeant anions. The apparent Km of 35SO42- uptake is 0.4 mM. 3. These results indicate that the nucleotide carrier in chromaffin granules has a broad specificity, transporting compounds with two strong negative charges. 4. Amino acid probes influence the uptake of ATP and catecholamines differently. Pyridoxal phosphate inhibits both uptake processes, 4,4'-di-isothiocyanostilbene-2,2'-disulphonic acid preferentially blocks ATP uptake, whereas phenylglyoxal blocks only ATP transport. It is suggested that the nucleotide carrier possesses arginine residues in a functionally important position. 5. The significance of these results obtained on isolated granules for the function of chromaffin granules within the cell is discussed.

Abstract
A new methodology was developed to study the cell-surface glycoproteins of cultured human skin fibroblasts. This was based on the binding of a variety of biotinyl-lectins to nitrocellulose electrophoretic transfers of total fibroblast lysates after separation in sodium dodecyl sulphate/polyacrylamide gels, followed by reaction with avidin-biotinyl-peroxidase complexes and detection with 3,3'-diaminobenzidine. The technique proved to be very sensitive and a large number of glycoproteins were detected by binding of concanavalin A and wheat-germ agglutinin. Binding of peanut agglutinin and to a lesser extent of Ricinus communis agglutinin I were found to be dependent on prior removal of sialic acid residues from the glycoproteins. Since by treatment of intact viable cells with neuraminidase only external sialic acid residues were removed, peanut agglutinin and Ricinus communis agglutinin I could thus be utilized for selective detection of cell-surface glycoproteins. Also, because peanut agglutinin was known to bind preferentially to oligosaccharides of the O-glycosidic type, and Ricinus communis agglutinin I to those of the N-glycosidic type, the two lectins were complementary in displaying the surface glycoproteins and in providing information about their oligosaccharide composition.

Abstract
The related probes phenylisothiocyanate and p-sulfophenylisothiocyanate possess comparable reactivity with nucleophiles but are dissimilar in their solubility characteristics. The reagents are utilized to topologically characterize the sites of covalent interaction with the Ca2+-stimulated ATPase of sarcoplasmic reticulum membranes. The hydrophobic probe phenylisothiocyanate binds covalently to the membrane-integrated protein. The extent of covalent interaction of this probe is reduced to a limited level of label incorporation by either preincubation with p-sulfophenylisothiocyanate or by exposing the labeled protein to alkaline reductive conditions. With respect to the chemical nature a dual interaction of phenylisothiocyanate is postulated. Phenylisothiocyanate modifies the Ca2+-ATPase hydrophobically. In addition, aqueous-exposed nucleophiles (cysteine thiols) interact with both arylisothiocyanates. Inhibition of the Ca2+-stimulated ATPase activity is effected by either probe.

Abstract
The asymmetric distribution of carbohydrate on biological membranes has provided the basis for the development of lectin-affinity methodology which permits the isolation of sealed, inside-out membrane fractions from heterogeneous populations of vesicles. Optimal conditions for these separations have been assessed employing purified right-side-out and inside-out vesicles derived from the plasma membrane of human erythrocytes as a model system. In this special case, homogeneous populations of defined polarity can be produced by varying the ionic conditions during formation of the vesicles. Surface-specific enzymic markers exist also for monitoring the integrity and orientation of a given population. Multivalent lectins such as wheat germ agglutinin and soya bean agglutinin which induce direct agglutination of erythrocyte membrane fragments containing accessible carbohydrate residues, selectively remove more than 90% of right-side-out and non-sealed membrane from a mixed population, a reaction which is inhibited by GluNAc or GalNAc, respectively. Non-agglutinating lectins, e.g. concanavalin A, immobilized on an inert matrix such as Sepharose 4B, may be employed to adsorb out specifically vesicles with exposed glycopeptides on their surface. In this technique, it is necessary normally to remove the non-sealed membranes on Dextran density gradients prior to the final preparation of inside-out vesicles on Con A-Sepharose. Finally, selective immunoprecipitation of fragments with accessible sugars may also be achieved after treatment with a non-agglutinating lectin (concanavalin A) followed by incubation with anti-concanavalin A IgG which promotes rapid aggregation of membrane containing exposed receptors for the lectin. These procedures should prove generally suitable for the isolation of tightly-sealed, inside-out membrane populations in a variety of biological systems. Pure populations of vesicles, exhibiting reversed polarity, are valuable in surface-labelling studies for investigating the structure, function and transmembrane distribution of integral membrane proteins/glycoproteins.

Abstract
Previous histochemical and biochemical localizations of alkaline phosphatase in Bacillus licheniformis MC14 have shown that the membrane-associated form of the enzyme is located on the inner surface of the cytoplasmic membrane, and soluble forms are located in the periplasmic space and in the growth medium. The distribution of salt-extractable alkaline phosphatase on the surfaces of the cytoplasmic membrane of B. licheniformis MC14 was determined by using lactoperoxidase-125I labeling techniques. Cells harvested during rapid alkaline phosphatase production were converted to protoplasts or lysed protoplasts and labeled. Analysis of the data obtained indicated that 30% of the salt-extractable, membrane-associated alkaline phosphatase was located on the outer surface of the cytoplasmic membrane, whereas 70% of the membrane-associated enzyme was localized on the inner surface. Controls for protoplast integrity (release of tritiated thymidine or examination of cytoplasmic proteins for label content) indicated excellent protoplast stability. Controls indicated that chemical labeling was not a factor in the apparent distribution of alkaline phosphatase on the membrane. These results support the previously reported histochemical localization of alkaline phosphatase on the membrane inner surface. The presence of alkaline phosphatase on the membrane outer surface is reasonable, considering the soluble forms of the enzyme found in the periplasmic region and in the culture medium.

Abstract
This and the companion article are aimed at surveying the methods used for the study of membrane asymmetry. The techniques employed for the assessment of the asymmetric distribution and orientation of membrane proteins are reviewed in this article, whereas those pertaining to the unequal distribution of lipids are detailed in the companion paper. The use of immunological techniques and lectins, functions of proteins and their perturbations, chemical reagents, enzymatic isotopic labeling and enzymatic cleavage of membrane proteins and physical techniques are discussed and illustrated using recent examples of their application. Whenever appropriate, problems involving crypticity and non-availability or non-reactivity of functional sites, relevant chemical functions or protein fragments to appropriate ligands, reagents or modifying enzymes are envisaged and possible modification of the exposure of proteins during preparation of ghosts and other drawbacks are discussed, the use of different techniques and control experiments in conjunction is recommended for a more realistic assessment of the distribution and orientation of proteins.

Abstract
Surface proteins and glycoproteins of intact human red blood cells were labelled with 125I by the lactoperoxidase method. The radioactive proteins were then separated in each of the Fairbanks and Laemmli one-dimensional polyacrylamide gel electrophoresis systems. The radioactive polypeptides had different mobilities in the two systems, largely due to the anomalous migration of glycoproteins in polyacrylamide gels. A two-dimensional system was therefore developed using the Fairbanks and Laemmli buffer systems to exploit these anomalies. This procedure clearly resolved radioactive glycoproteins and proteins and enabled the identification of many more surface components than had previously proved possible.

Abstract
The indirect immunoferritin labeling method was used to localize the membrane-bound respiratory nitrate reductase in membrane vesicles and protoplasts or sphereplasts of Bacillus licheniformis and Klebsiella aerogenes, respectively. For a comparison of the labeling of the various vesicle preparations, which differed not only in size but also in the percentage of inside-out orientation, a quantification of the results was needed to circumvent the problem of non-specifically bound ferritin. From the results of sidedness of the nitrate reductase in the cytoplasmic membrane of the above-mentioned bacteria was determined as being cytoplasmic in B. licheniformis and as transmembranous in K. aerogenes.

Abstract
The injection of [2,3-3H]N-succinimidyl propionate ([3H]N-SP) into the rat sciatic nerve was used to covalently label both intra- and extra-axonal proteins. While extra-axonal proteins (e.g., myelin proteins) remained in the injection site, the intra-axonal proteins were transported in both the anterograde and retrograde directions. The mobile labeled proteins appeared to move by normal axonal transport processes because: (a) autoradiographic studies showed that they were localized exclusively within the axon at considerable distances from the injection site, (b) specific and identifiable proteins (by SDS gel electrophoresis) moved at expected rates in the anterograde direction, and (c) an entirely different profile of proteins moved in the anterograde vs. retrograde direction. This novel experimental approach to axonal transport, which is independent of de novo protein synthesis, provided a unique view of slow anterograde transport, and particularly of retrograde transport of endogenous proteins. A large quantity of a 68,000 mol wt proteins, moving at approximately 3-6 mm/day, dominated the retograde transport profile. [3H]N-SP, therefore, represents a new and unique "vital stain" which may find many applications in cell biology.

Abstract
Extracellularly applied N-succinimidyl [2,3-3H]propionate was used in vivo to covalently label intra-axonal proteins in the rat sciatic nerve. This technique permitted a unique view of axonal transport of proteins independent of biosynthesis. The proteins detected in slow anterograde transport (1 to 2 millimeters per day) correspond to cytoskeletal proteins described in previous papers. The slowly retrogradely transported component (3 to 6 millimeters per day) was composed primarily of a single protein with a molecular weight of 68,000.

Abstract
1. The distribution of phosphatidylethanolamine, the major lipid of Erwinia carotovora, was investigated in intact bacteria, spheroplasts and outer- and inner-membrane preparations, with the amino-group reagent 2,4,6-trinitrobenzenesulphonic acid. Only 4% was found on the external surface of the outer membrane with 30% on the internal surface, whereas the inner membrane had 27 and 38% on its external and internal surfaces respectively. Some comparative studies were made with three other bacteria. 2. The fluidity of the membranes of E. carotovora was studied by using the fluorescent probe 1,6-diphenylhexa-1,3,5-triene. Results were consistent with the hydrocarbon region of the outer membrane bilayer being less fluid than that of the inner one. 3. On the basis of these and other results a model for the outer- and inner-membrane structures of E. carotovora is proposed.

Abstract
Erythrocyte and HeLa cell plasma membranes were isolated on polylysine-coated polyacrylamide beads and the transbilayer disposition of their proteins was investigated. When membranes of intact erythrocytes were isolated on beads and then labelled by lactoperoxidase-catalysed iodination, their labelling pattern was similar to that of inside-out vesicles in solution. When the membranes of intact HeLa cells were isolated on beads and then labelled by galactose oxidase-[3H]borohydride treatment, no glycoprotein or glycolipid sugars were accessible. On the other hand, when the HeLa cell membranes were isolated on beads and then labelled by the lactoperoxidase-catalysed iodination, all of the major membrane proteins were iodinated. These experiments confirmed for HeLa cell membranes what had previously been shown for erythrocyte membranes: when the membranes of intact cells are isolated on beads, the accessibility of their surfaces to enzymatic probes is the same as would be expected of inside-out vesicles in suspension. Double-label experiments, in which the HeLa cell membranes were labelled first on the intact HeLa cells and again after isolation on beads, identified several proteins which may span the membrane.

Abstract
During growth of the ovarian follicle, the mammalian oocyte becomes surrounded by an acellular coat called the zona pellucida. Whether the zona pellucida originates from the oocyte, surrounding follicle cells, or both has remained an unresolved issue. In experiments described here, denuded and follicle-enclosed mouse oocytes at various stages of growth were isolated and cultured in vitro in the presence of either [(35)S]methionine or [(3)H]fucose in order to determine the site of synthesis of the three, recently identified, zona pellucida proteins, ZP1, ZP2, and ZP3 [Bleil, J. D. & Wassarman, P. M. (1980) Dev. Biol., in press]. Approximately 1.5% of the [(35)S]methionine, and as much as 45% of the [(3)H]fucose, that was incorporated into trichloroacetic acid-insoluble material by denuded or follicle-enclosed oocytes during a 12-hr culture period was found associated with zonae pellucidae removed from the cultured oocytes. Incorporation of [(35)S]methionine into zona pellucida proteins was depressed to less than 1/50th when denuded oocytes were cultured in the presence of puromycin, and secretion of zona pellucida proteins by denuded oocytes was demonstrated by pulse-chase experiments. Sodium dodecyl sulfate/polyacrylamide gel electrophoresis of [(35)S]methionine- and [(3)H]fucose-labeled proteins present in oocytes, zonae pellucidae, and follicle cells revealed that denuded oocytes synthesize and secrete zona pellucida proteins, whereas no evidence was obtained to suggest that follicle cells synthesize these proteins. Denuded oocytes, ranging in diameter from 48 to 68 mum, incorporated both [(35)S]methionine and [(3)H]fucose into zona pellucida proteins during culture in vitro, whereas zonae pellucidae removed from fully-grown oocytes (85 mum) were not radiolabeled to a significant extent. After culture of denuded or follicle-enclosed oocytes for 12 hr, more than 95% of the [(3)H]fucose incorporated into oocyte proteins was found in ZP1, ZP2, and ZP3, indicating that the zona pellucida proteins are the major class of proteins glycosylated during oocyte growth. These results provide biochemical evidence supporting the idea that the zona pellucida originates from the mammalian oocyte itself, rather than from the surrounding follicle cells.

Abstract
A membrane fraction with sarcolemmal properties was purified from the smooth muscle layers (myometrium) of rat uterus by successive differential and equilibrium centrifugation in sucrose. The putative sarcolemmal fraction was identified by iodination with [125I]iodosulfanilic acid, had an equilibrium density of 1.15, and was enriched in enzyme activities usually associated with the plasma membrane including 5'-nucleotidase (EC 3.1.3.5) and (Na+ + K+) ATPase (EC 3.6.1.3). These membranes were free of mitochondrial or nuclear membrane contamination, suggesting the relative enrichment of sarcolemmal membranes in the fraction. Proteins of the membranes were heterogeneous with respect to molecular weight, but only a few were labelled when intact muscle was radioiodinated. Uniform resistance of sarcolemmal proteins to trypsin digestion and salt extraction suggested many are tightly bound or intrinsic membrane proteins and was a further indication of the homogeneity of membranes in this fraction.

Abstract
1. Diazotized 2,6-diiodosulfanilic acid (DDISA) appears to have properties suitable to serve as an artificial, non-penetrating label of cell surface membranes. Therefore, the conditions for selective labeling of cell surface membranes as compared to intracellular proteins as well as a method for its chemical determination were explored in the present study. 2. DDISA reacts with alpha-naphthol at neutral pH to produce a compound (1-hydroxy-4-(2,6-diiodo-4-sulfo-1-phenylazo-(naphthylene)), DSPN) with a characteristic spectrum in the visible range (Amax 430 nm). The absorbance of the reaction product, DSPN, is linearly proportional to the concentration of DDISA and can be used as a method for the colorimetric determination of DDISA. Reaction of DDISA with a molar excess of alpha-naphthol was also used as a method for inactivating unreacted DDISA to terminate labeling prior to cell fractionation. 3. [125I]DDISA reacts avidly with a variety of basic, neutral and acidic proteins as well as with cell membranes to form an acid-stable covalent azo linkage. 4. Effectiveness of labeling of the surface membrane of intact erythrocytes after incubation with [125I]DDISA was assessed by th ratio of 125I incorporated into membrane proteins compared to intracellular proteins. When intact erythrocytes were exposed to [125I]DDISA, the optimal labeling of membranes occurred at 37 degrees C after 20 min of incubation time and at a concentration of 10(-4) M [125I]DDISA in the incubation media. Under these conditions the ratio of the specific activity (cpm 125I/mg protein) of the membrane fraction to the specific activity of the soluble protein fraction (membrane/supernatant ratio) was greater than 500. When incubations were conducted at 4 degrees C this ratio was less than 50. However, when osmotically lysed erythrocytes were incubated with [125I]DDISA the majority of the label reacted with the soluble protein fraction resulting in a membrane/supernatant ratio of 0.14. 5. The results thus suggest that [125I]DDISA used under the appropriate incubation conditions, including the inactivation and removal of [125I]DDISA by washing with alpha-naphthol, can serve as a highly selective membrane label with minimal incorporation into intracellular soluble proteins. The general applicability of this method for other cell types remains to be explored.

Abstract
A method is described for detecting 3H-labelled proteins in immunoelectrophoretic systems performed on agarose gels. The method is based on the incorporation of a polyacrylamide gel into the agarose gel after the electrophoresis. This mixed gel has the characteristics of a polyacrylamide gel, making it possible to use fluorography as has been described for polyacrylamide gels. The applicability of the fluorography method is demonstrated by analyzing 3H-labelled human serum albumin and 3H-labelled pig intestinal brush border proteins by quantitative immunoelectrophoresis.
