Process for the enzymatic hydrolysis of a D- alpha -amino-acid amide to the corresponding D- alpha -amino-acid, wherein an aqueous solution of the D- alpha -amino-acid amide is contacted with an aminoacylamidase-containing preparation obtained from a culture of Rhodococcus erythropolis or a ...
(Fig. 4A). The release of the EVs from non-cross-linked hydrogel, as well as cross-linked hydrogel in the presence andabsenceof UV/blue light was studied, whose differences are depicted inFig. 4B. The mechanism of release is based on the hydrolysis of the polymeric network, as well as...
The transporting α-subunit contains many membrane-spanning regions, and the sites for proton and potassium binding and translocation as well as ATP hydrolysis. The smaller β-subunit, on the other hand, only passes through the membrane a single time, and does not possess any catalytic or ...
Process for the enzymatic hydrolysis of a D-α-amino-acid amide to the corresponding D-α-amino-acid, wherein an aqueous solution of the D-α-amino-acid amide is contacted with an aminoacylamidase-containing preparation obtained from a culture of Rhodococcus erythropolis or a mutant thereof and...
The regioselective and chemoselective hydrolysis of an &agr;- ester group of an amino acid diester using pig liver esterase enzyme (PLE) is disclosed. The amino acid diesters may be either N-protected or unprotected and the diester groups may be the same or different. In particular, the prepa...
all proteins upon theirhydrolysisyield a class of simplercompounds, the building blocks of proteins, called amino acids. The simplest amino acid is calledglycine, named for its sweet taste (glyco, “sugar”). It was one of the first amino acids to be identified, having been isolated from the...
Our results demonstrate that absent pseudoallylic strain, a 1,3-diaxial interaction of an amide with a carboxylic acid leads to only a 2400-fold increase in the rate of amide bond cleavage as compared with the rate of hydrolysis of an unactivated peptide bond....
Fatty-acid amide hydrolase (FAAH) is an intracellular serine enzyme that catalyzes the hydrolysis of bioactive fatty-acid ethanolamides such as anandamide ... D Fegley,S Gaetani,A Duranti,... 被引量: 5发表: 2004年 The fatty-acid amide hydrolase inhibitor URB597 inhibits MICA/B shedding ...
The enantioselective hydrolysis of p-nitrophenyl esters of alpha-amino acids (Phe, Leu, Ala) was accomplished in micelles formed with the surfactants bearing one or two sugar-amide headgroups. The effect of structural variations in such sugar-amide surfactants on the rates and enantioselectivity (kD...
Synthesis of diglygolic acid functionalized nanoparticles (FGA-1) Preparation of Fe3O4nanoparticles (F-1) The magnetite (Fe3O4) nanoparticles were prepared by a slightly modified previous method named oxidative hydrolysis26. Firstly, FeSO4.7H2O (26 mmol) was dissolved in deionized water (24...
