Binding of Griffonia simplicifolia I lectin to rat pulmonary alveolar macrophages and its use in purifying type II alveolar epithelial cells
(Elsevier, 1986-01-23)
We report that the isolectin Griffonia simplicifolia I-B4 isolated from G. simplicifolia seeds binds to rat alveolar macrophages present in frozen sections of lung tissue or bronchoalveolar lavage fluid. G. simplicifolia ...
Properties of diacylglycerol kinase in adult and fetal rat lung
(Elsevier, 1982-12-13)
Diacylglycerol kinase activity is found in both adult and fetal lung. Approximately 27 and 52% of the total activity is found in microsomes and cytosol, respectively. The activity is maximal at pH 7.4. The apparent Km for ...
Structural studies of capsular polysaccharide of type XII diplococcus pneumoniae
(Elsevier, 1974-10)
The capsular polysaccharide of Diplococcus pneumoniae Type XII contains residues of -glucose and -galactose in a molar ratio of 2:1. The methylated polysaccharide yielded upon hydrolysis 2,3,4,6-tetra- and 3,4,6-tri-O-me ...
Structure of a water-insoluble -glucan isolated from a streptococcal organism
(Elsevier, 1983-08-16)
The structure of the extracellular polysaccharide (water-insoluble -glucan) from an anaerobic, Gram-positive coccus organism (Streptococcus) has been investigated. Acid hydrolysis of the methylated glucan yielded 2,3,4,6-tetra-, ...
Evidence for a regulatory role of CTP : Choline phosphate cytidylyltransferase in the synthesis of phosphatidylcholine in fetal lung following premature birth
(Elsevier, 1981-07-24)
The sequence of reactions which function to incorporate choline into phosphatidylcholine was investigated in lung from fetuses following premature delivery. The rate of [methyl-14C]choline incorporation by rat lung slices ...
D-Glucuronic acid: A non-inhibitor of the concanavalin A system
(Elsevier, 1972-06-22)
D-Glucuronic acid is demonstrated not to inhibit the concanavalin A system; previous claims to the contrary are shown to be due to a pH effect. Concanavalin A does not precipitate biopolymers containing nonreducing, terminal ...
The content of diacylglycerol, triacylglycerol and monoacylglycerol and a comparison of the structural and metabolic heterogeneity of diacylglycerols and phosphatidylcholine during rat lung development
(Elsevier, 1981-04-23)
The content of diacylglycerol in fetal rat lung is approx. 36% of the adult and rapidly increases to adult levels by 1 day after birth. Triacylglycerol content is also low (23%) and increases to adult levels between 1 and ...
Tritium exchange reactions catalyzed by 2-oxo-4-hydroxyglutarate aldolase from Escherichia coli K-12
(Elsevier, 1979-05-10)
Tritiated water and tritiated substrates have been used to study exchange reactions catalyzed by Escherichia coli 2-oxo-4-hydroxyglutarate aldolase (4-hydroxy-2-oxoglutarate glyoxylate-lyase, EC 4.1.3.16, 2-oxo-4-hydroxyglutarate ...
An "extension" of the carbohydrate binding specificity of concanavalin A
(Elsevier, 1973-08-30)
Evidence based on the quantitative precipitin method and hapten inhibition technique demonstrates that concanavalin A may interact with internal 2-O-linked [alpha]--mannopyranosyl residues as may occur in glycoproteins and ...
Soluble cytochrome b5 reductase from human erythrocytes
(Elsevier, 1972-07-12)
1. An enzyme that catalyzes the reduction of erythrocyte cytochrome b5 has been isolated from the supernatant fraction of erythrocyte hemolysates by chromatography on DEAE-cellulose, Amberlite CG-50, and Bio-Gel P-60.2. ...
