the present study was carried out to investigate the effects of different levels of canola meal eithr with or without phytase addition on laying hen's performance. a number of 288 layer hens (the strains of hy-line w36) at the 60th week of age, selected as based on the same egg production percentage and body weight were, assigned to a factorial arrangement with a completely randomized desi...

In this research, the interaction of hexadecyl trimahyl ammonium bromide (HTAB) with enzyme ureasehas been investigated comprehensively at different experimental conditions such as ionic strength, proteinconcentration using ion selective membrane electrode of surfactants. The obtained binding isotherms frompotentiometnc studies have been analyzed by different theories such as Wyman binding pote...

The effect of supplementing two commercial multienzyme to diets included two barley cultivars (Sararood [71.99%] and Valfajr [66.39%]) on performance, egg quality, and blood parameters of laying hens was investigated in an 8-wk (65 to 73 wk of age) experiment.  The commercial multienzymes were Grindazym™ (with mainly β-glucanase and xylanase activity) and Hemicell® (with mainly β-mannanase acti...

copper amine oxidases (caos) catalyse the oxidative de-amination of biogenic amines which are ubiquitous compounds essential for cell growth and proliferation. the enzymes are homodimers containing both topaquinone and a cu(ii) ions as cofactors at the active site of each subunit. after extraction and purification of chickpea (cicer arietinum) amine oxidase by chromatoghraphy, km and vmax of th...

CYP719A14 structure analysis and its interaction with ligands via bioinformatic methods. Methods. Homologous modeling of three-dimensional enzyme. Molecular docking. Results. enzyme, which shows cheilanthifoline synthase activity, model was build based on results homologous modeling. Interaction built possible substrates – benzylisoquinoline compounds: (S)-Scoulerine, (S)-Cheilanthifoline, (S)-...

One of the most significant tasks for proteomic research and industrial applications, is the preparation of recyclable enzyme reactor. Herein, a novel recyclable enzyme reactor has been developed based on monodispersed spherical poly(quaternary ammonium ionic liquid)s particles immobilized trypsin. A new quaternary ammonium ionic liquids functional monomer was first synthesized. The ionic l...

a 2 × 3 factorial experiment was conducted to investigate the effect of enzyme endofeed w (eew) at 0 and 0.05%, thyme essential oil (teo), probiotic primalac® (pp) and non-feed additive, on intestinal histomorphology of broilers fed wheat-based diet. each of the 6 dietary treatments was replicated 4 times with 12 chicks each from 0 to 42 days of age. there was no interaction between enzyme and ...
