A PREVIOUS investigation1 has shown that enzymes from Chœtomium globosum are able to hydrolyse wheat straw xylan to xylose with the formation of a series of intermediates, designated a,b,c, … g, which appear on paper-chromatograms with regularly decreasing RF-values, and which are believed to be oligosaccharides with regularly increasing xylose units ...

The enzymatic hydrolysis of folate analogues
Biochemical Pharmacology, 1968Abstract The enrichment culture technique has been used to isolate bacteria which contain enzymes for the hydrolysis of the terminal amino acid in various folate analogues. Each of the three purified enzymes is specific for the hydrolysis of only one of the following compounds : 4-amino-4-deoxypteroylalanine, 4-amino-4-deoxypteroyl-aspartate and 4 ...

Semicontinuous enzymatic hydrolysis of lignocelluloses
Biotechnology and Bioengineering, 1991AbstractLignocelluloses (steamed hardwood and hardwood kraft pulp) were semicontinuously hydrolyzed on a large scale [2‐2. 5 kg of substrate vs. 20, 000 IU filter paperase (FPase)] using a 10‐L hydrolysis reactor with an ultrafiltration unit for the recovery and reuse of cellulases.

Mechanisms of enzymatic glycoside hydrolysis
Current Opinion in Structural Biology, 1994The determination of a large number of three-dimensional structures of glycosidases, both free and in complex with ligands, has provided valuable new insights into glycosidase catalysis, especially when coupled with results from studies of specifically labelled glycosidases and kinetic analyses of point mutants.

The enzymatic acylation and hydrolysis of lysolecithin
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1965The present experiments show that lysolecithin is converted to lecithin by ratliver preparations which are free from cell particles. In this process lysolecithin is esterfied directly rather than being degraded to simpler compounds which are subsequently incorporated into lecithin. Two separate reactions are postulated whereby lysolecithin is converted

Enzymatic hydrolysis of prolyl- and hydroxyprolylnaphthylamides
Archives of Biochemistry and Biophysics, 1956Abstract 1. 1. Two chromogenic iminopeptides, l -prolyl- and hydroxy- l -prolyl-β-naphthylamides, were prepared, and the kinetics of hydrolysis of the prolyl compound were investigated. 2. 2. Attempts to employ these substrates histochemically with frozen-dried tissues were unsuccessful. 3. 3.

Enzymatic hydrolysis of nucleoside phosphoramidates
Life Sciences, 1973Abstract The nucleoside phosphoramidate thymidine-5′-phospho-α-naphthylamidate and thymidine-3′-phospho-α-naphthylamidate were prepared as fluorogenic substrates for the study of enzymatic hydrolysis of the PN bond. With these new substrates, the rate and specificity of hydrolysis of the PN bond of the nucleoside phosphoramidate by snake venom and ...

Enzymatic Hydrolysis of Atracurium In Vivo
Anesthesiology, 1985Inactivation of atracurium in vivo has been postulated to proceed along two pathways: Hofmann elimination and ester hydrolysis. Since an end product of Hofmann elimination (acrylate) may be potentially toxic, the authors conducted a study to determine the extent of degradation via enzyme-catalyzed hydrolysis relative to that via Hofmann elimination ...

Kinetics of the enzymatic hydrolysis of cellulose
Biotechnology and Bioengineering, 1984AbstractEnzymatic hydrolysis of cellulose for sugar production offers advantages of higher conversion, minimal by‐product formation, low energy requirements, and mild operating conditions over other chemical conversions. The development of a kinetic model, based on observable, macroscopic properties of the overall system, is helpful in design and ...
