Designing Hydrolytic Zinc Metalloenzymes
Zinc is an essential element required for the function of more than 300 enzymes spanning all classes. Despite years of dedicated study, questions regarding the connections between primary and secondary metal ligands and protein structure and function remain unanswered, despite numerous mechanistic, structural, biochemical, and synthetic model studies. Protein design is a powerful strategy for r...
متن کاملProstacyclin Modulates Cholesteryl Ester Hydrolytic
our previous experiments indicated that smooth muscle cells (SMC) in neointima of injured rabbit aorta (a) acquire the capacity to produce PGI2 and (b) have increased lysosomal CE hydrolytic (acid cholesteryl ester hydrolase [ACEH])activity. Using cultured SMC from rabbit thoracic aorta, we demonstrated that PGI2, 6-keto-PGF1,, and 6-keto-PGE, enhanced ACEH activity fourfold. No significant eff...
متن کاملHydrolytic Reactions of Esters and
The hydrolytic reactions of esters and amides of thiosulphurous acid ate investigated in a homogeneous medium. The esters are hydrolysed by alkali to gire sulphide, sulphite and thiosulphate whereas the amides are resistant towards alkali. Both the esters and amides are hydrolysed by acids giving hydrogen sulphide, sulphur dioxide, polythionates and elemental sulphur. The hydrolysis of these es...
متن کاملHydrolytic enzymes of Moraxella bovis.
Certain strains of Moraxella bovis produce tissue-damaging enzymes which may initiate or potentiate infectious bovine keratoconjunctivitis. Thirteen reference strains of this species were characterized physiologically and screened for production of various enzymes by some conventional biochemical tests and the API ZYM system (Analytab Products, Plainview, N.Y.). All 13 strains were hemolytic. A...
متن کاملProduction of Hydrolytic Depolymerising Pectinases
Polygalacturonases (PGases) or hydrolytic depolymerases are enzymes involved in the degradation of pectic substances. They have a wide range of applications in food and textile processing, degumming of plant rough fibres and treatment of pectic wastewaters. Bacteria, yeasts and fungi under both submerged (SmF) and solid-state fermentation (SSF) conditions produce these enzymes. Bacteria produce...
