Abstract
We investigated the effect of salinity on the relationship between Na(+)-K(+)-ATPase and sulfogalactosyl ceramide (SGC) in the basolateral membrane of rainbow trout (Oncorhynchus mykiss) gill epithelium. SGC has been implicated as a cofactor in Na(+)-K(+)-ATPase activity, especially in Na(+)-K(+)-ATPase rich tissues. However, whole-tissue studies have questioned this role in the fish gill. We re-examined SGC cofactor function from a gill basolateral membrane perspective. Nine SGC fatty acid species were quantified by tandem mass spectrometry (MS/MS) and related to Na(+)-K(+)-ATPase activity in trout acclimated to freshwater or brackish water (20 ppt). While Na(+)-K(+)-ATPase activity increased, the total concentration and relative proportion of SGC isoforms remained constant between salinities. However, we noted a negative correlation between SGC concentration and Na(+)-K(+)-ATPase activity in fish exposed to brackish water, whereas no correlation existed in fish acclimated to freshwater. Differential Na(+)-K(+)-ATPase/SGC sensitivity is discussed in relation to enzyme isoform switching, the SGC cofactor site model and saltwater adaptation.

Abstract
The P3 murine monoclonal antibody (MAb) was generated by immunizing BALB/c mice with NeuGcGM3 included into liposomes. The specificity of this MAb was defined by an enzyme-linked immunosorbent assay and immunostaining on thin-layer chromatograms. P3 MAb binds to NeuGc-containing gangliosides and was shown also to react with sulfated glycolipids. A preliminary immunohistochemical study showed that the P3 MAb was able to recognize antigens expressed in human breast tumors.

Abstract
A significant improvement has been made in the desulfation step of our previously published HPLC determination of cerebrosides, sulfatides, and monogalactosyl diacylglycerols (Nonaka, G. and Kishimoto, Y., Biochim. Biophys. Acta 572 (1978) 423-431). Instead of the original two-phase reaction, a solution of trifluoroacetic acid in ethyl acetate is used for the solvolysis in the new method. The revised method was used to determine the levels of cerebrosides and sulfatides in rat kidney. Among four individual glycosphingolipids studied, hydroxysulfatide was present at the highest level (0.7-1.3 nmol/mg of dry tissue), followed by nonhydroxysulfatide (0.3-0.8 nmol/mg of dry tissue). Hydroxycerebroside (0.09-0.16 nmol/mg of dry tissue) and nonhydroxycerebroside (0.03-0.09 nmol/mg of dry tissue) were present in smaller quantities. There appear to be no significant differences between male and female animals of different ages (30-120 days), although the amounts decreased slightly in older animals and there was a higher concentration in female than in male kidney. Tissue size was significantly smaller in females. The homolog composition of rat kidney sulfatide was studied by reverse-phase HPLC, and was found to be significantly different from that reported in human kidney. Rat sulfatides contained fatty acids with a higher degree of saturation and longer chain length. Preliminary studies indicated that rat kidney contained unusually large quantities of C25:1 and C27:1 fatty acids and also that there was more C26:1 than C24:1 acid. In brain of the same animals the ratio of nonhydroxy to hydroxysulfatide decreased with age (1.5:1 in 30-day-old brain; 1:1 at 90 days).

Abstract
Sodium efflux was studied in 22Na-loaded red blood cells in the presence of arylsulfatase, an enzyme that specifically hydrolyzes sulfatide. Sodium efflux was inhibited in proportion to the amount of arylsulfatase present. Maximum inhibition was almost as high as the efflux obtained in medium with K+ absent. At maximum inhibition 83.2% of the sulfatide content of the fragmented red blood cell membranes was hydrolyzed and ouabain-sensitive (Na+ + K+)-ATPase activity was inhibited by 100%. Sodium efflux, sulfatide content, and (Na+ + K+)-ATPase activity were unaffected with arylsulfatase in the presence of a high concentration of sulfatide. These results indicate that sulfatide plays a specific role in sodium and potassium ion transport. They also suggest that most sulfatide is localized externally in the red blood cell membrane.

Abstract
(1) (Na+ + K+)-ATPas from the rectal glands of Squalus acanthias, solubilized in octaethylene glycol dodecyl monoether (2 mg detergent/mg protein), retains its activity for days when stored at 0 degrees C both with and without 20% glycerol. Glycerol protects partially against inactivation at higher temperatures. (2) Solubilization leads to a decrease in the amount of lipids bound per mg protein. 50 mol phospholipids and 40 mol cholesterol are bound per 265 000 g protein. 90% of the phospholipid is phosphatidylcholine (72%) and phosphatidylethanolamine (18%) and there is about 1 mol acidic phospholipid per 265 000 g. In addition, the protein has about 27 000 g carbohydrate as hexose, hexosamine and sialic acid bound per 265 000 g. (3) The calculation of the molecular weight from an In C vs. r2 plot obtained by sedimentation equilibrium centrifugaton in the presence of 560 microM detergent gives a molecular weight of the protein part of the active solubilized enzyme of 265 000 using the measured values for bound detergent, lipid (phospholipid + cholesterol) and carbohydrate. The sedimentation coefficient (S20,w) is 10.1 S, giving a Stokes' radius of 77 A. (4) An increase in detergent concentration to 56 mM dissociates the 10.1 S particle into particles with a sedimentation coefficient of 5.8 S and a molecular weight of 139 000 (Stokes' radius, 66 A). In the presence of this detergent concentration the enzyme is inactive. (5) The molecular weights of the soijm dodecyl sulphate-solubilized, isolated alpha- and beta-chains are found to be 106 000 and 40 000, respectively. (6) It is concluded that the active solubilized enzyme is an (alpha beta)2 structure and that it dissociates into an enzymatically inactive alpha beta structure when the detergent-to-protein ratio is increased.

Abstract
Cholesteryl sodium sulphate (CS) crystallizes as the dihydrate, the crystal structure of which is known. On heating the dihydrate, solid state phase transitions are observed at 65 degrees C and 95 degrees C and melting occurs at 165 degrees C. The structure of the high temperature phase has not been determined. Cholesteryl dihydrogen phosphate (CP) is not isostructural with any phases of CS. It undergoes a phase transition at 50 degrees C and melts at 190 degrees C. In systems with water CS is unstable whereas it was possible to determine the phase diagram of CP. In most of the composition range a crystalline hydrate is in equilibrium with a gel-phase. The latter has remarkable properties in that lamellar order exists with the 46 A lipid bilayer interleaved with water layers up to 1000 A. The monofilm behaviour of CS and CP at different pH levels is also reported.

Abstract
1. The presence of concanavalin A binding sugars in the glycoprotein component of a partially purified (Na++K+) ATPase preparation from dog fish salt gland was demonstrated by binding of a Triton X-100 extract of the enzyme and isolated glycoprotein to concanavalin A-Sepharose, and by binding of membrane-associated enzyme to free concanavalin A. 2. The binding of concanavalin A to the glycoprotein in both membrane-associated enzyme and a Lubrol extract of the enzyme had no effect on (Na++K+)-ATPase activity. Binding was completely inhibited by methyl-alpha-mannoside. Also, enzyme activity was not affected by removal of 50% of glycoprotein sialic acid by neuraminidase. These results suggest that the carbohydrate moiety of the glycoprotein does not play a catalytic role in the (Na++K+)-ATPase. 3. When a Triton X-100 extract of (Na++K+)-ATPase was chromatographed on concanavalin A-Sepharose, 37% of total protein was bound to the column and eluted by methyl-alpha-mannoside. The bound fraction was free of lipid, and contained not only the glycoprotein but also the large protein which is the catalytic subunit of the enzyme, and small amounts of other membrane derived proteins. The ratio of large protein to glycoprotein, as measured by the relative Coomassie blue absorbance of the two proteins separated by gel electrophoresis, was the same in the bound fraction as in the membrane. These results suggest that the glycoprotein and lareg protein are either associated together in the membrane or become associated during lipid replacement by Triton.

Abstract
The lipophilic components of choline phosphoglycerides and ethanolamine phosphoglycerides obtained from the salt gland of herring gull and eider duck and from the rectal gland of spiny dogfish were investigated by means of thin-layer chromatography, gas chromatography, and gas chromatography-mass spectrometry. All phospholipids analyzed were shown to contain small amounts of plasmalogens, and mainly C16, C18, and C18:1 aldehyde was detected. The fatty acids were composed of saturated, unsaturated, straight chain, and branched chain types, ranging between 14-22 carbon atoms. The lipophilic composition of the rectal gland phospholipids showed a higher degree of unsaturation and the presence of more branched chain fatty acids than that of the birds, possibly related to body temperature.
