Enzymic hydrolysis of steroid phosphates
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1968Abstract Steroid phosphates were used as substrates for alkaline and acid phospliatases from different sources to determine the structural specificity of the compounds that undergo enzymic hydrolysis. The steroid 21-, 3β- and 3α-phosphates were hydrolyzed by the acid and alkaline phosphatases tested.

An improved enzymic hydrolysis of collagen
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1971Abstract A peptidase mixture was prepared from hog-kidney microsomes which contained aminopeptidase, prolidase, prolinase, carboxypeptidase-P, and X-prolyl-aminopeptidase activity. The sequential addition of collagenase, papain, and the peptidase mixture to collagen samples resulted in the hydrolysis of 90% of the peptide bonds.

Hydrolysis of peptide esters by different enzymes
International Journal of Peptide and Protein Research, 1992The combined use in peptide synthesis of the Fmoc‐group with methyl, benzyl or p‐nitro benzyl esters is not practical because of the elimination of the Fmoc‐group under basic conditions and by catalytic hydrogenation. Nevertheless the solution synthesis of peptides requires those combinations in some cases.

Enzymic hydrolysis of N:N-dimethylcarbamoyl fluoride
Biochemical Pharmacology, 1959Abstract The hydrolysis ofN:N-dimethylcarbamoyl fluoride by rabbit tissues and by various vertebrate plasmata has been studied. The hydrolysis of this compound by rabbit liver and kidney homogenates involves an enzyme distinct from that hydrolysing di iso propoxyphosphoryl fluoride.

Enzymic hydrolysis of sphingolipids. Hydrolysis of ceramide glucoside by an enzyme from ox brain
Biochemical Journal, 1966Ceramide glucoside (1-O-glucosido-2-N-acyl-sphingosine) was hydrolysed to ceramide (N-acyl-sphingosine) and glucose by beta-glucosidase from ox brain. The reaction was stimulated by the non-ionic detergent, Triton X-100, or by the anionic detergents, cholate or taurocholate.

Hydrolysis of organophosphorus compounds by microbial enzymes
Applied Microbiology and Biotechnology, 2010There are classes of microbial enzymes that have the ability to degrade harmful organophosphorus (OP) compounds that are present in some pesticides and nerve agents. To date, the most studied and potentially important OP-degrading enzymes are organophosphorus hydrolase (OPH) and organophosphorus acid anhydrolase (OPAA), which have both been ...

Enzymic hydrolysis of sphingolipids. Hydrolysis of ceramide lactoside by an enzyme from rat brain
Biochemical Journal, 1966Ceramide lactoside [1-O-(galactosido-4-beta-glucosido)-2-N-acyl-sphingosine] was hydrolysed to ceramide glucoside and galactose by beta-galactosidase of rat brain. The reaction was not reversible, required cholate or taurocholate, had optimum pH5.0 and K(m) 2.2x10(-5)m.

The hydrolysis of ochratoxin a by some proteolytic enzymes
Biochemical Pharmacology, 1969Ochratoxin A, a metabolite produced by a strain of Aspergillus ochraceus and causing enteritis, renal necrosis, an increase of glycogen in the liver when given to rats, as well as inhibiting the phosphorylase enzyme in vitro, is found to be hydrolyzed in vivo to an iso-coumarin derivative (ochratoxin a).

The hydrolysis of xylan and xylooligosaccharides by ruminal enzymes
Archives of Biochemistry and Biophysics, 1957Abstract Xylan is hydrolyzed to a mixture of xylooligosaccharides by enzymes in the rumen of the bovine. A random hydrolysis of the xylosidic bonds of xylan, xylotetraose, xylotriose, and xylobiose is effected. Several bacterial cultures obtained from the rumen contents were shown to produce xylan-hydrolyzing enzymes.

Accessory Enzymes Involved in the Hydrolysis of Xylans
1991Xylans are heteropolysaccharides which are depolymerized by β-1,4-D-endoxylanases. Due to the abundance and variety of substituents in native xylans, different accessory enzymes are also needed for the total hydrolysis of xylan. The knowledge of α-glucuronidase, α-arabinosidase, and acetyl xylan- and feruloyl esterases has increased considerably in ...
