Here we report a comprehensive analysis through alanine-scanning mutagenesis of the contribution of surface ion pairs to the thermal stability of Alicyclobacillus acidocaldarius esterase 2 (EST2). We produced 16 single mutants, 4 double mutants corresponding to selected ion pairs R31/E118, E43/K102, R58/D130, D145/R148, 2 double mutants (R63A/R98A and E50A/D94A) involving residues of a large io...
The chimeric proteins viz. CBM3-Cel9A, CBM4-Cel9A and CBM30-Cel9A, are constructed by fusion of family 3, 4, and 30 cellulose binding modules (CBMs) to N-terminus of family 9 endoglucanase (Cel9A) from Alicyclobacillus acidocaldrious. The chimeric enzymes were successfully expressed in Escherichia coli and purified to homogeneity. The chimeric enzymes showed significant increase in Avicel (8-12...
A 1341 bp sequence of the 16S rDNA of an undescribed species of Pasteuria that parasitizes the soybean cyst nematode, Heterodera glycines, was determined and then compared with a homologous sequence of Pasteuria ramosa, a parasite of cladoceran water fleas of the family Daphnidae. The two Pasteuria sequences, which diverged from each other by a dissimilarity index of 7%, also were compared with...
The definition of food quality may differ for processors and consumers, but generally organoleptic characteristics, such as flavour, odour and appearance, as well as extended shelf life are among the most important of its attributes. Spoilage of food by microbial contamination may occur at any point during production, altering any one or all of these characteristics renders the product unusable...
