The reaction of aldolase with 2-methylmaleic anhydride.
1. The reaction of rabbit muscle aldolase with 2-methylmaleic anhydride is described. All the protein amino groups can be reversibly blocked. 2. As the reaction proceeds, the enzyme activity decreases until, at about 50% citraconylation of amino groups, the enzyme is completely inhibited. At this stage, little or no dissociation of the enzyme tetramer is observed and 75% of the activity is reco...
متن کاملModification of Sugarcane Bagasse with Acetic Anhydride and Butyric Anhydride in Ionic Liquid 1-butyl-3-methylimidazolium Chloride
Bagasse acetate butyrates were prepared homogeneously in 1-butyl-3methylimidazolium chloride ([C4mim]Cl) ionic liquid from ball-milled sugarcane bagasse by acylation with acetic anhydride and butyric anhydride. The parameters, including reaction temperature, reaction time, feeding method of adding anhydrides, the dosage of total anhydrides to SCB, and the molar ratio of acetic anhydride to buty...
متن کاملLabeling of high density lipoproteins with [3H] acetic anhydride.
Rat serum HDL was labeled by reaction with [3H] acetic anhydride at pH 7.2 for 30 min at room temperature by a modification of the method of Montelaro and Rueckert (1975. J. Biol. Chem. 250: 1413). Protein specific activities of 60 dpm/ng were achieved. Seven percent of the label was in lipid, of which 92 percent was recovered in phospholipid. The labeled HDL migrated as a single band as seen b...
متن کاملReaction of myoglobin with 3,3-tetramethyleneglutaric anhydride.
1. The extent of reaction of the protein with 3,3-tetramethyleneglutaric anhydride was measured by determining the loss of lysine and the equivalent appearance of 3,3-tetramethyleneglutarimidolysine in the hydrolysate at various time-intervals. Of the 19 lysine residues in sperm-whale myoglobin, three did not react with 3,3-tetramethyleneglutaric anhydride. Also, the N-terminal valine did not r...
متن کاملhe reaction rate of phithalic anhydride with urea in the presence of acetic acid from the freezing curve
antranilic acid is an intermediate material which we can produce by hofmann's rearrangement reaction. in this process phithalimide is a main reactant. one procedure for produceing phthalimide is the reaction of phithalic anhydride with urea in the presence of acetic acid. in this research, the kinetics of this reaction was studied at 115 c. we found that the reaction of phthalic anhydride ...
