The aim of this study was to determine the inhibitory effects of feed ingredients on protease activities of Argyrosomus regius larvae using in vitro techniques. A. regius larvae fed on a commercial feeding procedure were sampled thirteen times, during the sampling period (from 3 to 32 days after hatching (DAH)). The differences observed in protease activities of meagre larvae during the samplin...

ω-Transaminases display complicated inhibitions by ketone products and both enantiomers of amine substrates. Here, we report the first example of ω-transaminase devoid of such inhibitions. Owing to the lack of enzyme inhibitions, the ω-transaminase from Ochrobactrum anthropi enabled efficient kinetic resolution of α-methylbenzylamine (500 mM) even without product removal.

1. Chromatography on silica gel, combined with infrared spectrometry, has been used to analyse mixtures of bile acids. 2. The results obtained by applying this method to an ox bile-salt preparation are described. Methyl lithocholate (methyl 3-hydroxycholanate) (1.8 mg.), methyl deoxycholate (methyl 3:12-dihydroxycholanate) (38 mg.), methyl chenodeoxycholate (methyl 3:7-dihydroxycholanate) (0-6 ...

Beta-1,3-glucanases are enzymes that hydrolyze beta-1,3-glucans, and they essential for the metabolism of seaweed, plants fungi. These also participate in digestion herbivore fungivore animals. Because importance these enzymes in insects, beta-1,3-glucanase inhibitors may be used development new control strategies against agricultural pests disease vectors. Beta-1,3-glucanase inhibito...

Despite an extensive literature on the brain substrates of response inhibition, it still remains to be determined which is the best functional comparison to tease apart neural activity underlying this cognitive process. Here we aimed to shed light on this issue be recording event-related potentials while participants performed a modified stop-signal task that allowed us to compare the following...
