Chemical modification studies on the [alpha]--galactopyranosyl binding lectin from the seeds of Bandeiraea simplicifolia
(Elsevier, 1976-07-19)
The role of amino, carboxyl and sulfhydryl groups in the binding of carbohydrate ligands to the [alpha]--galactopyranosyl binding lectin from Bandeiraea simplicifolia has been evaluated using specific chemical modification ...
Carbohydrate-binding specificity of the daffodil (Narcissus pseudonarcissus) and amaryllis (Hippeastrum hybr.) bulb lectins
(Elsevier, 1990-06)
The carbohydrate binding specificity of the daffodil (Narcissus pseudonarcissus; NPA) and amaryllis (Hippeastrum hybr.; HHA) lectins, isolated from extracts of their bulbs by affinity chromatography on immobilized mannose, ...
Protein-carbohydrate interaction : V. Further inhibition studies directed toward defining the stereochemical requirements of the reactive sites of concanavalin A
(Elsevier, 1967-07)
Inhibition studies on the concanavalin A-dextran interaction have been extended using as inhibitors the members of the maltose-, isomaltose-, and methyl [alpha]-isomaltoside series, amino and N-acetyl amino sugars, and a ...
Biphasic kinetic plots and specific analogs distinguishing and describing amino acid transport sites in S37 ascites tumor cells
(Elsevier, 1975-06-25)
Curve-fitting procedures indicated that exo-2-amino-bicyclo-(2,2,1)-heptane-2-carboxylic acid (BCH) modified V and Km for one of two systems serving for histidine transport into the S37 ascites tumor cells. When this system ...
Studies on the estimation of deoxyribonucleic acid and ribonucleic acid in rat brain
(Elsevier, 1963)
A method for the estimation of DNA and RNA in rat brain is described. The principal modifications of preexisting methods involve initial lipid extraction with chloroform-methanol and continuous stirring during alkaline ...
Equilibrium dialysis and carbohydrate-binding studies on the 2-acetamido-2-deoxy--glucopyranosyl-binding lectin from Bandeiraea simplicifolia seeds
(Elsevier, 1978-03)
The carbohydrate-binding specificity of Bandeiraea simplicifolia lectin II (BS II lectin) has been studied by quantitative precipitin and hapten-inhibition analysis. The BS II lectin precipitated biopolymers having nonreducing ...
Reinvestigation of the structure of 1-aminocyclohexane-1-carboxylic acid hydrochloride (C 7 H 14 ClNO 2 )
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1975-09)
Studies in molecular structure, symmetry and conformation II
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Company Limited ; Springer Science+Business Media, 1971-04)
1-Aminocycloheptanecarboxylic acid hydrobromide monohydrate crystallizes in space group P 2 1 2 1 2 1 with cell dimensions a = 25·69, b = 6·85 and c = 6·61 Å. The structure was solved in the hk 0 and h 0 l projections, and ...
Seed germination studies II. Pathways for starch degradation in germinating pea seedlings
(Elsevier, 1966-07-06)
Amylase activity is present in extracts of the axis tissue of etiolated pea seedlings. Several lines of evidence establish that this starch-hydrolyzing activity is due to the presence of a [beta]-amylase ([alpha]-1,4-glucan ...
Immunocytochemistry of sequence-related neuropeptides in Drosophila
(Elsevier, 1993-06)
Based on structure, activity, and expression, the Drosophila drosulfakinin I peptide (DSK I; FDDY(OSO3H)GHMRFamide) is similar to the vertebrate peptide, cholecystokinin.1 Dromyosuppressin (DMS; TDVDHVFLRFamide) is an ...
