The structure of thioredoxin from Alicyclobacillus acidocaldarius (previously named Bacillus acidocaldarius ) (BacTrx) and from Escherichia coli ( E. coli Trx) was studied by Fourier-transform IR spectroscopy. Two mutants of BacTrx [Lys(18)-->Gly (K18G) and Arg(82)-->Glu (R82E)] were also analysed. The data revealed similar secondary structures in all proteins, but BacTrx and its mutants showed...
Alicyclobacillus acidoterrestris (A. acidoterrestris) is a bacillus-type spore former that causes significant alterations in fruit products. It is highly resistant to typical pasteurization regimes; thus, this work explored the use of high-pressure CO₂ (HPCD) for its deactivation in apple cream. The assays were conducted in a high-pressure apparatus where the cream was placed in an agitated ves...
The stability of two thermophilic esterases, AFEST from Archaeoglobus fulgidus and EST2 from Alicyclobacillus acidocaldarius, against the denaturing action of urea and guanidine hydrochloride has been investigated by means of steady-state fluorescence and circular dichroism measurements. Experimental results indicate that the two enzymes, even though very resistant to temperature and urea, show...
BACKGROUND Conceptually, multi-functional enzymes are attractive because in the case of complex polymer hydrolysis having two or more activities defined by a single enzyme offers the possibility of synergy and reduced enzyme cocktail complexity. Nevertheless, multi-functional enzymes are quite rare and are generally multi-domain assemblies with each activity being defined by a separate protein ...
