Improved substrate specificity for D-galactose of L-arabinose isomerase for industrial application
Biochimica Et Biophysica Acta - Proteins and Proteomics, 2018L-Arabinose isomerase isolated from Geobacillus stearothermophilus (GSAI) was modified to improve its substrate specificity for D-galactose for the production of D-tagatose, a potential reduced-energy sweetener. Among the selected residues, mutation at residue 18 produced a mutant strain, H18T, which exhibited increased activity for D-galactose ...

The double-site variant (C450S-N475K) L-arabinose isomerase (L-AI) from Geobacillus thermodenitrificans catalyzes the isomerization of D-galactose to D-tagatose, a functional sweetener. Using a substrate-docking homology model, the residues near to D-galactose O6 were identified as Met186, Phe280, and Ile371.

Characterization of an L-arabinose isomerase from Bacillus subtilis
Applied Microbiology and Biotechnology, 2009An isolated gene from Bacillus subtilis str. 168 encoding a putative isomerase was proposed as an L-arabinose isomerase (L-AI), cloned into Escherichia coli, and its nucleotide sequence was determined. DNA sequence analysis revealed an open reading frame of 1,491 bp, capable of encoding a polypeptide of 496 amino acid residues.

l -arabinose isomerases: Characteristics, modification, and application
Trends in Food Science & Technology, 2018Abstract Background d -Tagatose, a ketose isomer of d -galactose, is a kind of rare sugar existing in nature. The sweetness of d -tagatose is comparable to that of sucrose, but d -tagatose has a relatively lower energy content, indicating that it is an ideal substitute for sucrose in daily life.
