ENZYMATIC BREAKDOWN OF THREONINE BY THREONINE ALDOLASE [PDF]
Journal of General Physiology, 1954 1. The enzyme which splits threonine to acetaldehyde and glycine has been partially purified from rat liver (five- to sixfold purification) and the name threonine aldolase proposed for it. 2. The general properties of threonine aldolase have been studied. The enzyme is unstable to a pH below 5. The pH optimum of the enzyme reaction is at

Threonine Requirement and Threonine Imbalance in Broiler Chickens
Poultry Science, 1994 Three experiments were conducted to determine the effect of excess dietary protein on threonine requirement of broiler chicks to 14 d of age (Experiments 1 and 2) and to determine the threonine requirement from 16 to 28 d of age (Experiment 3). Two dietary protein levels were used in Experiments 1 and 2:20% CP in a threonine-limiting basal diet ...

Stereochemistry of the Conversions of
European Journal of Biochemistry, 1980 dl[3‐2H]Threonine, l‐[3‐2H]threonine, (2RS,3S)‐2‐amino[3‐2H1] butanoic acid, (2RS,3S) 2‐amino[3‐3H1]butanoic acid and dl‐2‐amino[3‐14C]butanoic acid were synthesised. l‐[3‐2‐H]Threonine was converted into l‐[4‐2H1]isoleucine by Serratia marcescens strain IHr313.

USING THREONINE, CANTHAXANTHINAND SODIUM SULPHATE AS DIETARY SUPPLEMENTATION FOR IMPROVING EGG PRODUCTION IN LAYING HENS IN POST PEAK PERIOD [PDF]
Egyptian Poultry Science, 2021 This study examines the hypothesis that threonine(THR),canthaxanthin (CAN)and sodium sulphate (SS)supplementation can improve the performance of commercial Lohmann Brown (LB) laying hens in late egg production period (44 – 56 wks).A total number of ...

A study on L-threonine and L-serine uptake in Escherichia coli K-12 [PDF]
, 2023 In the current study, we report the identification and characterization of the yifK gene product as a novel amino acid carrier in E. coli K-12 cells. Both phenotypic and biochemical analyses showed that YifK acts as a permease specific to L-threonine and,
